<strong><br />
Quick Answer</strong>
</p>
<p>
	Choose หรือ manage the certificate based on the hostnames you need to protect, the validation level, the server platfหรือm และ whether you control <span class="caps">DNS</span>. Keep the private key secure, complete validation, install the full certificate chain และ verify the live <span class="caps">HTTPS</span> connection befหรือe relying on the<span class="widont">&nbsp;</span>certificate.
</p>
<p>
	<strong><br />
Befหรือe You Begin</strong>
</p>
<ul>
	<li>
		Identify every hostname the certificate must cover.
	</li>
	<li>
		ยืนยัน that you control DNS หรือ the required validation channel.
	</li>
	<li>
		Generate และ securely retain the private key when a CSR is required.
	</li>
</ul>

This guide will help you configure <span class="caps">SSL</span>/<span class="caps">TLS</span><span class="widont">&nbsp;</span>cหรือrectly.
</p>
<ol>
	<li>
		<p>
			What is HTTPS? HTTPS (Hypertext Transfer Protocol Secure) encrypts data between ของคุณ website และ its visitหรือs. It ก่อนหน้าents eavesdropping และ ensures data integrity.
		</p>
	</li>
	<li>
		<p>
			Obtaining an ใบรับรอง SSL NICENIC provides trusted SSL certificates. You can learn mหรือe และ ซื้อ/configure a certificate ที่นี่: <a href="https://nicenic.com/ssl-certificates/" target="_blank" rel="nofollow noopener">https://nicenic.com/ssl-certificates/</a>
		</p>
	</li>
	<li>
		<p>
			Installing the ใบรับรอง SSL ติดตาม ของคุณ web server's instructions to install the certificate. Common servers include: Apache: <a href="https://httpd.apache.org/docs/current/ssl/ssl_howto.html" target="_blank" rel="nofollow noopener">https://httpd.apache.org/docs/current/ssl/ssl_howto.html</a> Nginx: <a href="https://nginx.org/en/docs/http/configuring_https_servers.html" target="_blank" rel="nofollow noopener">https://nginx.org/en/docs/http/configuring_https_servers.html</a> IIS (Windows): <a href="https://docs.microsoft.com/en-us/iis/manage/configuring-security/how-to-set-up-ssl-on-iis" target="_blank" rel="nofollow noopener">https://docs.microsoft.com/en-us/iis/manage/configuring-security/how-to-set-up-ssl-on-iis</a>
		</p>
	</li>
	<li>
		<p>
			Enfหรือce HTTPS Once ของคุณ certificate is installed: Redirect all HTTP traffic to HTTPS. Update internal links และ resources to use HTTPS. Verify that ของคุณ website is fully accessible via HTTPS.
		</p>
	</li>
	<li>
		<p>
			Keep ใบรับรอง อัปเดตแล้ว SSL certificates have expiration dates. Ensure certificates are renewed befหรือe they expire และ check ของคุณ website regularly to maintain uninterrupted secure connections.
		</p>
	</li>
</ol>
<p>
	<strong><br />
How to Verify</strong>
</p>
<p>
	เปิด the <span class="caps">HTTPS</span> site from a clean browser session และ inspect the certificate subject, <span class="caps">SAN</span> hostnames, issuer, validity dates และ chain. Test every hostname covered by the certificate และ confirm that <span class="caps">HTTP</span> redirects behave as<span class="widont">&nbsp;</span>intended.
</p>
<p>
	<strong><br />
Troubleshooting</strong>
</p>
<ul>
	<li>
		DNS validation recหรือds are missing, incหรือrect หรือ added at the wrong DNS provider.
	</li>
	<li>
		The certificate does not include the hostname being opened.
	</li>
	<li>
		The private key does not match the certificate หรือ CSR.
	</li>
	<li>
		The server is missing an intermediate certificate หรือ is still presenting the old certificate.
	</li>
</ul>
<p>
	<strong><br />คำถามที่พบบ่อย </strong>
</p>
<p>
	<strong>Can I reuse the same certificate after moving<span class="widont">&nbsp;</span>servers?</strong>
</p>
<p>
	Often the certificate can be reinstalled if you still have the matching private key และ the certificate remains valid. Reissue it when the key, <span class="caps">CSR</span> หรือ certificate details must<span class="widont">&nbsp;</span>change.
</p>
<p>
	<strong>Why does the browser still show the old<span class="widont">&nbsp;</span>certificate?</strong>
</p>
<p>
	The server หรือ load balancer may still present the old certificate, another virtual host may be selected, หรือ an intermediate cache may not have reloaded the<span class="widont">&nbsp;</span>configuration.
</p>
<p>
	<strong>When should I submit a<span class="widont">&nbsp;</span>ticket?</strong>
</p>
<p>
	ส่ง a ticket when validation remains pending after the published recหรือds are visible, หรือ when the NiceNIC หรือder does not provide the expected certificate<span class="widont">&nbsp;</span>files.

<![CDATA[
	<strong><span style="font-size:16px;">How to Set Up และ Troubleshoot DNSSEC fหรือ Your โดเมน?</span></strong><br />
<br />
<span style="font-size:16px;"> DNSSEC helps protect ของคุณ โดเมน’s DNS recหรือds from being tampered with during DNS resolution. It adds a layer of verification so that DNS resolvers can confirm the DNS response really comes from the cหรือrect source.</span><br />
<br />
<strong><span style="font-size:16px;">ที่ NiceNIC, DNSSEC usually involves two sides:</span></strong><br />
<span style="font-size:16px;"> Your DNS provider หรือ nameserver provider generates the DNSSEC recหรือds.</span><br />
<span style="font-size:16px;"> NiceNIC, as ของคุณ โดเมน registrar, helps submit the DS recหรือds to the registry when the TLD suppหรือts DNSSEC.</span><br />
<br />
<span style="font-size:16px;"> หาก DNSSEC is not configured cหรือrectly, ของคุณ โดเมน may show DNSSEC errหรือs, หรือ in mหรือe serious cases, some users may not be able to access ของคุณ website.</span><br />
<br />
<strong><span style="font-size:16px;">What Is DNSSEC?</span></strong><br />
<span style="font-size:16px;"> DNSSEC stและs fหรือ ชื่อโดเมน System Security Extensions.</span><br />
<span style="font-size:16px;"> In simple terms, DNSSEC helps verify that the DNS answer fหรือ ของคุณ โดเมน has not been changed หรือ fหรือged during the lookup process.</span><br />
<span style="font-size:16px;"> Fหรือ example, when someone visits ของคุณ website, DNS is used to find the cหรือrect server IP address. DNSSEC helps make sure that the DNS result is authentic และ has not been replaced with false data.</span><br />
<span style="font-size:16px;"> DNSSEC does not replace SSL, website security, hosting security, หรือ email security. It only helps protect the DNS resolution process.</span><br />
<br />
<strong><span style="font-size:16px;">When Do You Need DNSSEC?</span></strong><br />
<ol>
	<li>
		<span style="font-size:16px;">You may want to enable DNSSEC if:</span> 
	</li>
	<li>
		<span style="font-size:16px;">Your website hและles sensitive user infหรือmation.</span> 
	</li>
	<li>
		<span style="font-size:16px;">You run business email, login systems, payment pages, หรือ customer pหรือtals.</span> 
	</li>
	<li>
		<span style="font-size:16px;">You want stronger โดเมน security.</span> 
	</li>
	<li>
		<span style="font-size:16px;">Your DNS provider suppหรือts DNSSEC.</span> 
	</li>
	<li>
		<span style="font-size:16px;">Your โดเมน extension suppหรือts DNSSEC.</span> 
	</li>
</ol>
<span style="font-size:16px;">หาก you are not familiar with DNS management, we recommend confirming with ของคุณ DNS provider befหรือe enabling DNSSEC.</span><br />
<span style="font-size:16px;"> Incหรือrect DNSSEC settings may affect โดเมน resolution.</span><br />
<br />
<strong><span style="font-size:16px;">Impหรือtant DNSSEC ระยะเวลาs</span></strong><br />
<strong><span style="font-size:16px;">DNSKEY:&nbsp;</span></strong><span style="font-size:16px;">A DNSKEY recหรือd is generated by ของคุณ DNS provider. It is used as part of the DNSSEC validation process.</span><br />
<strong><span style="font-size:16px;">DS Recหรือd:&nbsp;</span></strong><span style="font-size:16px;">A DS recหรือd connects ของคุณ โดเมน’s DNSSEC setup with the parent registry zone.&nbsp;In most cases, ของคุณ DNS provider gives you the DS recหรือd, และ you need to add it through ของคุณ registrar.</span><br />
<strong><span style="font-size:16px;">ชื่อserver:&nbsp;</span></strong><span style="font-size:16px;">Your nameservers decide wที่นี่ ของคุณ โดเมน’s DNS recหรือds are managed. หาก you change nameservers, ของคุณ DNSSEC recหรือds may also need to be updated.</span><br />
<br />
<strong><span style="font-size:16px;">How to Enable DNSSEC fหรือ Your โดเมน</span></strong><br />
<span style="font-size:16px;"><strong>Befหรือe You Begin</strong><strong>: Back Up Your DNS Recหรือds</strong></span><br style="font-size:16px;" />
<span style="font-size:16px;">Befหรือe enabling DNSSEC, save a copy of ของคุณ current DNS recหรือds, especially impหรือtant A, AAAA, CNAME, MX, TXT, และ CAA recหรือds. Enabling DNSSEC does not nหรือmally change these recหรือds, but keeping a backup makes it easier to verify หรือ restหรือe ของคุณ DNS configuration if you also change nameservers หรือ DNS providers.</span><br style="font-size:16px;" />
<span style="font-size:16px;">หาก needed, see: How to Back Up DNS Recหรือds Befหรือe Changing โดเมน Settings.<br />
</span><br />
<strong><span style="font-size:16px;">Step 1: ตรวจสอบ Whether Your DNS Provider Suppหรือts DNSSEC</span></strong><br />
<span style="font-size:16px;"> เข้าสู่ระบบ to the platfหรือm wที่นี่ ของคุณ DNS is managed.</span><br />
<span style="font-size:16px;"> This may be:</span><br />
<span style="font-size:16px;"> Your โดเมน registrar, ที่นี่ is&nbsp;NiceNIC</span><br />
<span style="font-size:16px;"> Your hosting provider</span><br />
<span style="font-size:16px;"> Your DNS provider</span><br />
<span style="font-size:16px;"> Your own DNS server</span><br />
<span style="font-size:16px;"> Another third-party DNS บริการ</span><br />
<span style="font-size:16px;"> Make sure DNSSEC is suppหรือted และ enabled tที่นี่.<br />
<strong>Impหรือtant</strong>: Enable DNSSEC และ DNSSEC signing at ของคุณ current DNS provider first. Only add the DS recหรือd at NiceNIC after ของคุณ DNS provider has generated the DNSSEC infหรือmation และ is publishing the cหรือresponding DNSKEY. เพิ่มing a DS recหรือd befหรือe the DNS provider is ready may cause DNSSEC validation to fail.</span><br />
<br />
<strong><span style="font-size:16px;">Step 2: รับ the DS Recหรือd from Your DNS Provider</span></strong><br />
<span style="font-size:16px;"> After enabling DNSSEC, ของคุณ DNS provider should provide DNSSEC infหรือmation such as:</span><br />
<span style="font-size:16px;"> Key Tag</span><br />
<span style="font-size:16px;"> Algหรือithm</span><br />
<span style="font-size:16px;"> Digest ประเภท</span><br />
<span style="font-size:16px;"> Digest</span><br />
<span style="font-size:16px;"> DS Recหรือd</span><br />
<span style="font-size:16px;"> Please copy the infหรือmation exactly as provided.</span><br />
<span style="font-size:16px;"> Even one incหรือrect character may cause DNSSEC validation failure.</span><br />
<br />
<strong><span style="font-size:16px;">Step 3: เพิ่ม the DS Recหรือd in Your NiceNIC Account</span></strong><br />
<span style="font-size:16px;"> เข้าสู่ระบบ to ของคุณ NiceNIC account และ go to ของคุณ โดเมน management page.</span><br />
<span style="font-size:16px;"> Then add the DS recหรือd provided by ของคุณ DNS provider.</span><br />
<span style="font-size:16px;"> หาก you are not sure wที่นี่ to add it, please contact our suppหรือt team และ provide the DS recหรือd from ของคุณ DNS provider.</span><br />
<br />
<strong></strong><strong><span style="font-size:16px;">Step 4: Wait fหรือ DNSSEC Propagation</span></strong><br />
<span style="font-size:16px;"> After the DS recหรือd is added, it may take some time fหรือ the update to propagate.</span><br />
<span style="font-size:16px;"> During this period, DNSSEC check results may not update immediately.</span><br />
<br />
<strong><span style="font-size:16px;">Step 5: Verify DNSSEC สถานะ</span></strong><br />
<span style="font-size:16px;"> After propagation, you may check ของคุณ โดเมน’s DNSSEC status using a DNSSEC checking tool หรือ by contacting our suppหรือt team.</span><br />
<span style="font-size:16px;"> หาก DNSSEC is cหรือrectly configured, the DNSSEC validation result should show a valid chain of trust.</span><br />
<br />
<strong><span style="font-size:16px;">When Should You Disable หรือ ลบ DNSSEC?</span></strong><br />
<span style="font-size:16px;"> You may need to remove หรือ update DNSSEC recหรือds if:</span><br />
<ul>
	<li>
		<span style="font-size:16px;">You changed ของคุณ nameservers.</span> 
	</li>
	<li>
		<span style="font-size:16px;">You moved DNS management to another provider.</span> 
	</li>
	<li>
		<span style="font-size:16px;">Your DNS provider disabled DNSSEC.</span> 
	</li>
	<li>
		<span style="font-size:16px;">Your DS recหรือd no longer matches the current DNSKEY.</span> 
	</li>
	<li>
		<span style="font-size:16px;">Your website หรือ email has DNS resolution issues after a DNS change.</span> 
	</li>
</ul>
<span style="font-size:16px;"><strong>Impหรือtant:</strong> หาก you are moving to a new DNS provider หรือ changing authหรือitative nameservers while DNSSEC is enabled, check fหรือ existing DS recหรือds befหรือe making the change.<br />
หาก the old DS recหรือd will no longer match the new DNS provider, remove the old DS recหรือd first และ wait fหรือ its full TTL to expire at the parent zone befหรือe changing nameservers. Keep DNSSEC signing active at the old DNS provider during this waiting period.<br />
After the new nameservers are active และ DNSSEC signing is enabled at the new DNS provider, obtain the new DS recหรือd และ add it through NiceNIC.<br />
Changing nameservers while resolvers still have the old DS recหรือd cached may cause DNSSEC validation failures และ SERVFAIL responses.</span><span style="font-size:16px;"><br />
<br />
<strong>Why Does My โดเมน ย้อนกลับ SERVFAIL After Enabling DNSSEC?</strong><br />
<strong>SERVFAIL </strong>can occur when DNSSEC validation fails. Common causes include:<br />
<ul>
	<li>
		<span style="font-size:16px;">An old หรือ stale DS recหรือd from a ก่อนหน้าious DNS provider</span> 
	</li>
	<li>
		<span style="font-size:16px;">A DS recหรือd that does not match the DNSKEY published by the current DNS provider</span> 
	</li>
	<li>
		<span style="font-size:16px;">Multiple DS recหรือds wที่นี่ one หรือ mหรือe no longer match an active DNSSEC key</span> 
	</li>
	<li>
		<span style="font-size:16px;">DNSSEC signing is not active หรือ the required DNSKEY/RRSIG recหรือds are not being published cหรือrectly</span> 
	</li>
	<li>
		<span style="font-size:16px;">ชื่อservers were changed befหรือe the ก่อนหน้าious DS recหรือd had fully expired from DNS caches</span> 
	</li>
</ul>
หาก ของคุณ โดเมน resolves without DNSSEC validation but returns SERVFAIL through validating resolvers, this is a strong indication of a DNSSEC configuration problem.<br />
ตรวจสอบ the current nameservers, all DS recหรือds published fหรือ the โดเมน, และ the DNSKEY infหรือmation from ของคุณ active DNS provider. ลบ หรือ replace a DS recหรือd only after confirming that it is outdated หรือ incหรือrect. หาก you are unsure, contact ของคุณ DNS provider หรือ NiceNIC Suppหรือt befหรือe making changes.<br />
</span><br />
<strong><span style="font-size:16px;">Why Does My โดเมน Show "DNSSEC Infหรือmation Is Currently Unavailable"?</span></strong><br />
<span style="font-size:16px;"> You may see this message:</span><br />
<span style="font-size:16px;"> DNSSEC infหรือmation is currently unavailable fหรือ this โดเมน.</span><br />
<span style="font-size:16px;"> This can happen fหรือ several reasons:</span><br />
<ul>
	<li>
		<span style="font-size:16px;">DNSSEC has not been enabled fหรือ this โดเมน.</span> 
	</li>
	<li>
		<span style="font-size:16px;">ไม่ DS recหรือd has been added at the registrar level.</span> 
	</li>
	<li>
		<span style="font-size:16px;">The โดเมน's current nameservers do not suppหรือt DNSSEC.</span> 
	</li>
	<li>
		<span style="font-size:16px;">The โดเมน recently changed nameservers.</span> 
	</li>
	<li>

<br />
<strong><span style="font-size:16px;">คำถามที่พบบ่อย เกี่ยวกับเรา DNSSEC</span></strong><br />
<br />
<strong><span style="font-size:16px;">1. Is DNSSEC required fหรือ every โดเมน?</span></strong><br />
<span style="font-size:16px;"> ไม่. DNSSEC is not required fหรือ every โดเมน.</span><br />
<span style="font-size:16px;"> However, it is recommended fหรือ โดเมนs that need stronger DNS security, especially business websites, email บริการs, login systems, financial บริการs, และ customer pหรือtals.</span><br />
<span style="font-size:16px;"> หาก you are not sure whether you need DNSSEC, please confirm whether ของคุณ DNS provider suppหรือts it และ whether you are comfหรือtable managing DNSSEC recหรือds.</span><br />
<br />
<strong><span style="font-size:16px;">2. </span></strong><strong><span style="font-size:16px;">Is DNSSEC the same as SSL?</span></strong><br />
<span style="font-size:16px;"> ไม่.</span><br />
<span style="font-size:16px;"> SSL protects the connection between the user’s browser และ ของคุณ website.</span><br />
<span style="font-size:16px;"> DNSSEC protects DNS resolution by helping verify that DNS responses have not been tampered with.</span><br />
<span style="font-size:16px;"> Fหรือ better security, many websites use both SSL และ DNSSEC, but they are different technologies.</span><br />
<br />
<strong><span style="font-size:16px;">3. </span></strong><strong><span style="font-size:16px;">Can NiceNIC generate DNSSEC recหรือds fหรือ me?</span></strong><br />
<span style="font-size:16px;"> In most cases, DNSSEC recหรือds are generated by ของคุณ DNS provider, not by the registrar.</span><br />
<span style="font-size:16px;"> NiceNIC can help submit the DS recหรือd to the registry when the โดเมน extension suppหรือts DNSSEC.</span><br />
<span style="font-size:16px;"> หาก you use a third-party DNS provider, please enable DNSSEC tที่นี่ first และ then provide us with the DS recหรือd.</span><br />
<br />
<strong><span style="font-size:16px;">4. What should I check after changing nameservers, DNS providers, หรือ transferring my โดเมน?</span></strong><br />
<span style="font-size:16px;">Changing nameservers หรือ DNS providers can affect DNSSEC because the existing DS recหรือd may no longer match the DNSKEY published by the new DNS provider.<br />
A registrar transfer by itself does not necessarily mean that ของคุณ DNSSEC configuration must change. หาก ของคุณ nameservers และ DNS provider remain the same, first check whether the existing DS recหรือd is still present และ still matches the current DNSKEY.<br />
หาก you also changed nameservers หรือ DNS providers, check fหรือ old DS recหรือds และ follow the DNSSEC migration steps above befหรือe publishing a new DS recหรือd.<br />
Do not assume that DNSSEC was automatically removed during a โดเมน transfer. Always verify the โดเมน’s current DS และ DNSKEY status.</span><br />
<br />
<strong><span style="font-size:16px;">5. </span></strong><strong><span style="font-size:16px;">What happens if the DS recหรือd is wrong?</span></strong><br />
<span style="font-size:16px;"> หาก the DS recหรือd does not match the DNSKEY published by ของคุณ current DNS provider, DNSSEC validation may fail.</span><br />
<span style="font-size:16px;"> This may cause some DNS resolvers to reject the DNS response.</span><br />
<span style="font-size:16px;"> As a result, ของคุณ website, email, หรือ other บริการs may become unreachable fหรือ some users.</span><br />
<br />
<strong><span style="font-size:16px;">6. </span></strong><strong><span style="font-size:16px;">I do not use DNSSEC. Do I need to do anything?</span></strong><br />
<span style="font-size:16px;"> หาก you do not use DNSSEC และ ของคุณ โดเมน has no DS recหรือds, usually no action is needed.</span><br />
<span style="font-size:16px;"> However, if ของคุณ โดเมน has old DS recหรือds from a ก่อนหน้าious DNS provider, you should remove them to avoid DNSSEC validation problems.</span><br />
<br />
<strong><span style="font-size:16px;">7. </span></strong><strong><span style="font-size:16px;">Why does my DNSSEC status still show an errหรือ after I updated the recหรือd?</span></strong><br />
<span style="font-size:16px;"> DNSSEC updates may take time to propagate.</span><br />
<span style="font-size:16px;"> หาก you recently added, removed, หรือ changed DS recหรือds, please wait fหรือ DNS propagation และ check again later.</span><br />
<span style="font-size:16px;"> หาก the issue continues, please contact suppหรือt และ provide ของคุณ โดเมน name, current nameservers, และ DS recหรือd.</span><br />
<br />
<strong><span style="font-size:16px;">8. Can DNSSEC cause my website to stop wหรือking?</span></strong><br />
<span style="font-size:16px;"> ใช่, if DNSSEC is incหรือrectly configured.</span><br />
<span style="font-size:16px;"> Common causes include:</span><br />
<ul>
	<li>
		<span style="font-size:16px;">Wrong DS recหรือd</span> 
	</li>
	<li>
		<span style="font-size:16px;">Old DS recหรือd after nameserver change</span> 
	</li>
	<li>
		<span style="font-size:16px;">Missing DNSKEY</span> 
	</li>
	<li>
		<span style="font-size:16px;">DNS provider not publishing DNSSEC recหรือds cหรือrectly</span> 
	</li>
	<li>
		<span style="font-size:16px;">หมดอายุd หรือ invalid DNSSEC signatures</span> 
	</li>
</ul>
<span style="font-size:16px;">หาก ของคุณ website stops wหรือking after DNSSEC changes, please contact suppหรือt immediately.</span><br />
<br />
<strong><span style="font-size:16px;">9. </span></strong><strong><span style="font-size:16px;">Should I remove DNSSEC befหรือe changing nameservers?</span></strong><br />
<span style="font-size:16px;"> In many cases, yes.</span><br />
<span style="font-size:16px;"> หาก you are moving to a new DNS provider และ you are not sure how to migrate DNSSEC safely, removing the old DS recหรือd befหรือe changing nameservers can reduce the risk of DNSSEC validation failure.</span><br />
<span style="font-size:16px;"> After the new nameservers are active และ DNSSEC is enabled at the new DNS provider, you can add the new DS recหรือd again.</span><br />
<br />
<strong><span style="font-size:16px;">10. </span></strong><strong><span style="font-size:16px;">What should I do if I see “Failure to get DNSSEC info”?</span></strong><br />
<span style="font-size:16px;"> This usually means the system could not retrieve valid DNSSEC infหรือmation fหรือ the โดเมน.</span><br />
<span style="font-size:16px;"> Please check:</span><br />
<ul>
	<li>
		<span style="font-size:16px;">Whether DNSSEC is enabled</span> 
	</li>
	<li>
		<span style="font-size:16px;">Whether the DS recหรือd has been added</span> 
	</li>
	<li>
		<span style="font-size:16px;">Whether the nameservers suppหรือt DNSSEC</span> 
	</li>
	<li>
		<span style="font-size:16px;">Whether the DS recหรือd matches the DNSKEY</span> 
	</li>
	<li>
		<span style="font-size:16px;">Whether you recently changed nameservers</span> 
	</li>
</ul>
<span style="font-size:16px;">หาก you are not sure, please contact NiceNIC suppหรือt และ provide ของคุณ โดเมน name และ DNSSEC details from ของคุณ DNS provider.</span><br />

	<h2>
		<strong>How to Transfer ชื่อ เซิร์ฟเวอร์ During a โอนย้ายโดเมน?</strong>
	</h2>
<strong><br />
Quick Answer</strong>
</p>
<p>
	A successful โดเมน transfer depends on the โดเมน's eligibility, lock status, authหรือization method, registrant access และ registry rules. Prepare the โดเมน befหรือe หรือdering the transfer, keep the existing <span class="caps">DNS</span> active, และ monitหรือ the transfer until<span class="widont">&nbsp;</span>completion.
</p>
<p>
	<strong><br />
Befหรือe You Begin</strong>
</p>
<ul>
	<li>
		ยืนยัน the โดเมน และ registrant email are accessible.
	</li>
	<li>
		Recหรือd the current nameservers และ DNS recหรือds.
	</li>
	<li>
		ตรวจสอบ the โดเมน's expiry date, lock status และ any TLD-specific transfer rule.
	</li>
</ul>
<p>
	<strong><br />
NiceNIC Instructions</strong>
</p>
<p>
	Transferring nameservers During a โอนย้ายโดเมน หาก you're just transferring the โดเมน registration, ของคุณ hosting บริการ will be unaffected, และ tที่นี่ will be no need to change nameservers. Although the nameservers should be transferred as part of the process, it's always a good idea to have a recหรือd of them. หาก you wish to specify the nameservers to the default <span class="caps">DNS</span> servers as provided by NiceNIC you can reset the nameservers after the transfer has been completed. Steps เข้าสู่ระบบ to ของคุณ account. Select the ชื่อโดเมน tab. Select the โดเมน that you want to change nameservers<span class="widont">&nbsp;</span>fหรือ.
</p>
<p>
	From within the <span class="caps">DNS</span> เซิร์ฟเวอร์ section click on แก้ไข <span class="caps">DNS</span> Server. Change the nameservers as required, leaving any of the fields blank will retain the หรือiginal <span class="caps">DNS</span> server. The nameservers are not actually changed until the transfer process is complete. หาก you wish to make an immediate change to the nameservers, you may do so with the ผู้รับจดทะเบียน you are transferring<span class="widont">&nbsp;</span>from.
</p>
<p>
	<strong><br />
How to Verify</strong>
</p>
<p>
	ตรวจสอบ the transfer status in NiceNIC, confirm the registrar of recหรือd after completion, verify the authหรือitative nameservers, และ test website และ email resolution. Do not treat payment alone as proof that the transfer<span class="widont">&nbsp;</span>completed.
</p>
<p>
	<strong><br />
Troubleshooting</strong>
</p>
<ul>
	<li>
		The โดเมน is locked, too new, recently transferred หรือ otherwise restricted by policy.
	</li>
	<li>
		The EPP/Auth code is missing, expired หรือ copied incหรือrectly.
	</li>
	<li>
		The approval email cannot be received หรือ the registrant data is under verification.
	</li>
	<li>
		The โดเมน หรือ related DNS บริการ expires while the transfer is pending.
	</li>
</ul>
<p>
	<strong><br />คำถามที่พบบ่อย </strong>
</p>
<p>
	<strong>Does a transfer change my<span class="widont">&nbsp;</span>nameservers?</strong>
</p>
<p>
	A registrar transfer nหรือmally keeps the current nameservers, but you should recหรือd และ verify them befหรือe และ after the<span class="widont">&nbsp;</span>transfer.
</p>
<p>
	<strong>Can I edit the โดเมน while a transfer is<span class="widont">&nbsp;</span>pending?</strong>
</p>
<p>
	Some settings may be restricted during a pending transfer. Avoid unnecessary ownership, lock หรือ <span class="caps">DNS</span> changes until the transfer<span class="widont">&nbsp;</span>completes.
</p>
<p>
	<strong>When should I submit a<span class="widont">&nbsp;</span>ticket?</strong>
</p>
<p>
	ส่ง a ticket when the status is unclear, a <span class="caps">TLD</span> uses a special transfer process, หรือ the transfer remains blocked after you cหรือrect the stated<span class="widont">&nbsp;</span>issue.

	<h2>
		<strong>How to ตรวจสอบ Whether a โดเมน Is Eligible fหรือ Transfer</strong>
	</h2>
<strong><br />
Quick Answer</strong>
</p>
<p>
	Befหรือe starting a transfer, confirm that the โดเมน is active, unlocked, not restricted by a transfer lock หรือ dispute, และ eligible under the registry's rules. Make sure you can receive approval messages และ obtain the <span class="caps">EPP</span>/Auth code when the <span class="caps">TLD</span> requires<span class="widont">&nbsp;</span>one.
</p>
<p>
	<strong><br />
Befหรือe You Begin</strong>
</p>
<ul>
	<li>
		ยืนยัน the โดเมน และ registrant email are accessible.
	</li>
	<li>
		Recหรือd the current nameservers และ DNS recหรือds.
	</li>
	<li>
		ตรวจสอบ the โดเมน's expiry date, lock status และ any TLD-specific transfer rule.
	</li>
</ul>
<p>
	<strong><br />
NiceNIC Instructions</strong>
</p>
<p>
	Befหรือe purchasing the transfer of any gTLD (e.g.,.<span class="caps">COM</span> /.<span class="caps">NET</span> /.<span class="caps">หรือG</span> /.<span class="caps">BIZ</span> /.<span class="caps">INFO</span> etc.) หรือ new gTLD (e.g..<span class="caps">CLUB</span> /.<span class="caps">CLOUD</span> /.<span class="caps">TRADE</span> /.<span class="caps">TOP</span> etc.), make sure ของคุณ โดเมน meets the following<span class="widont">&nbsp;</span>conditions:
</p>
<ol>
	<li>
		<p>
			Your โดเมน was จดทะเบียนed หรือ transferred at least 60 days ago;
		</p>
	</li>
	<li>
		<p>
			The โดเมน is unlocked at the current ผู้รับจดทะเบียน (its WHOIS status should be OK หรือ Active). Also,you need to request an up-to-date Auth/EPPcode fหรือ the โดเมน at ของคุณ current ผู้รับจดทะเบียน. หาก all criteria are met, you should be able to complete the transfer successfully. Still, some ccTLDs (.ES และ.UK) have additional transfer requirements และ/หรือ exclude some points from the list above.
		</p>
	</li>
</ol>
<p>
	NOTE: Make sure the โดเมน status is active, not expired. หาก you wish to transfer an expired โดเมน to NiceNIC, please contact our Suppหรือt Team email <a href="/th/rss/support/mailto:support@nicenic.net">suppหรือt@nicenic.net</a> fหรือ further assistance.
</p>
<p>
	<strong><br />
How to Verify</strong>
</p>
<p>
	ตรวจสอบ the transfer status in NiceNIC, confirm the registrar of recหรือd after completion, verify the authหรือitative nameservers, และ test website และ email resolution. Do not treat payment alone as proof that the transfer<span class="widont">&nbsp;</span>completed.
</p>
<p>
	<strong><br />
Troubleshooting</strong>
</p>
<ul>
	<li>
		The โดเมน is locked, too new, recently transferred หรือ otherwise restricted by policy.
	</li>
	<li>
		The EPP/Auth code is missing, expired หรือ copied incหรือrectly.
	</li>
	<li>
		The approval email cannot be received หรือ the registrant data is under verification.
	</li>
	<li>
		The โดเมน หรือ related DNS บริการ expires while the transfer is pending.
	</li>
</ul>
<p>
	<strong><br />คำถามที่พบบ่อย </strong>
</p>
<p>
	<strong>Does a transfer change my<span class="widont">&nbsp;</span>nameservers?</strong>
</p>
<p>
	A registrar transfer nหรือmally keeps the current nameservers, but you should recหรือd และ verify them befหรือe และ after the<span class="widont">&nbsp;</span>transfer.
</p>
<p>
	<strong>Can I edit the โดเมน while a transfer is<span class="widont">&nbsp;</span>pending?</strong>
</p>
<p>
	Some settings may be restricted during a pending transfer. Avoid unnecessary ownership, lock หรือ <span class="caps">DNS</span> changes until the transfer<span class="widont">&nbsp;</span>completes.
</p>
<p>
	<strong>When should I submit a<span class="widont">&nbsp;</span>ticket?</strong>
</p>
<p>
	ส่ง a ticket when the status is unclear, a <span class="caps">TLD</span> uses a special transfer process, หรือ the transfer remains blocked after you cหรือrect the stated<span class="widont">&nbsp;</span>issue.

</p>
<p>
	Here, <code>a</code> authหรือizes hosts resolved by the sender โดเมน's A/<span class="caps">AAAA</span> recหรือds, <code>mx</code> authหรือizes the IPs of the โดเมน's <span class="caps">MX</span> hosts, และ <code>include:</code> delegates a check to another <span class="caps">SPF</span> recหรือd. <strong>Use only mechanisms ของคุณ actual email provider requires.</strong> Replace the fictional provider โดเมน befหรือe<span class="widont">&nbsp;</span>publishing.
</p>
<ul>
	<li>
		<code>-all</code> means unauthหรือized senders should fail SPF.
	</li>
	<li>
		<code>~all</code> indicates softfail; some providers recommend it during rollout.
	</li>
	<li>
		<code>?all</code> means neutral; it is not a substitute fหรือ confirming ของคุณ senders.
	</li>
	<li>
		Avoid the deprecated <code>ptr</code> mechanism และ do not combine multiple complete <code>v=spf1</code> policies.
	</li>
</ul>
<h2>

</h2>
<h2>
	Set up SPF
</h2>
<ol>
	<li>
		ตรวจสอบ existing TXT recหรือds fหรือ <code>v=spf1</code> at the hostname you send from.
	</li>
	<li>
		Combine all approved mail บริการs into <strong>one SPF policy fหรือ that hostname</strong>; do not add a second competing SPF TXT recหรือd.
	</li>
	<li>
		หาก NiceNIC is ของคุณ DNS host, open <strong>ผลิตภัณฑ์ของฉัน &gt; โดเมน &gt; DNS Recหรือds</strong>, edit/create a TXT recหรือd at the specified host, และ paste the validated policy.

</h2>
<h2>
	When SPF fails
</h2>
<p>
	ตรวจสอบ the sending server's actual public IP, whether the recipient evaluates the intended envelope sender โดเมน, และ whether the SPF recหรือd exceeds the DNS-lookup limit in <a href="https://datatracker.ietf.org/doc/html/rfc7208" target="_blank" rel="nofollow noopener">RFC 7208</a>.

	How to verify certificate installation cหรือrectly
</h2>
<p>
	<br />
Do not verify an <span class="caps">SSL</span> installation by looking fหรือ a website seal หรือ by checking that the browser no longer shows a warning on one computer. Verify the <strong><span class="caps">TLS</span> connection presented by the actual public<span class="widont">&nbsp;</span>hostname</strong>.
</p>
<h2>
	<br />
</h2>
<h2>
	The checks that matter
</h2>
<ol>
	<li>
		Visit <code>https://your-domain.example</code> on a clean browser session. ยืนยัน tที่นี่ is no certificate-name, expiry หรือ trust warning.
	</li>
	<li>
		Inspect the certificate's <strong>Subject Alternative ชื่อ (SAN)</strong> list. It must cover the hostname you requested, including <code>www</code> if ของคุณ site uses it.
	</li>
	<li>
		ยืนยัน the certificate is within its validity interval และ the server sends a complete, trusted chain to an appropriate public root.
	</li>
	<li>
		Test whether the site redirects HTTP traffic to HTTPS as intended และ does not load insecure assets ("mixed content").
	</li>
	<li>
		หาก ของคุณ บริการ has several IPs, load balancers, CDN edges หรือ IPv6 endpoints, test each relevant route; one server may still have an old certificate.
	</li>
</ol>
<h2>
	<br />
</h2>
<h2>
	Commและ-line check
</h2>
<p>
	openssl s_client -connect example.com:443 -servername example.com<span class="widont">&nbsp;</span>
</p>
<p>
	-verify_hostname example.com -verify_return_errหรือ -showcerts
</p>
<p>
	Replace <code>example.com</code> with ของคุณ hostname. ตรวจสอบ the hostname-verification และ certificate-chain result; the <code>-verify_hostname</code> option is impหรือtant because displaying the chain alone does <strong>not</strong> validate the requested hostname. These flags rely on the local เปิดSSL trust stหรือe. Inspect any missing intermediates. Fหรือ a hostname/path overview, you can also use a reputable external <span class="caps">TLS</span> diagnostic บริการ, but do not send credentials หรือ customer<span class="widont">&nbsp;</span>data.

	A certificate "trust badge" is optional marketing <span class="caps">UI</span>; it is <strong>not required</strong> fหรือ successful <span class="caps">TLS</span> deployment. หาก something fails, give NiceNIC Suppหรือt the hostname, <span class="caps">UTC</span> test time, observed certificate dates และ non-sensitive errหรือ text―not ของคุณ private<span class="widont">&nbsp;</span>key.
</p>
<h2>

<h2>
	Verify every advertised hostname, not just one URL
</h2>
<p>
	A company may serve <code>example.com</code>, <code>www.example.com</code>, <code>shop.example.com</code> และ <code>api.example.com</code> from different <span class="caps">TLS</span> endpoints. Test each hostname's <strong>actual live certificate</strong>: <span class="caps">SAN</span> coverage, trusted chain, issuance/expiry และ <span class="caps">HTTP</span>-to-<span class="caps">HTTPS</span> behaviหรือ.

</p>
<p>
	Use the เปิดSSL hostname-verification commและ shown above หรือ an external <span class="caps">TLS</span> test fหรือ each hostname. The <code>-servername</code> parameter sends <span class="caps">SNI</span> so the server can select the intended certificate; <code>-verify_hostname</code> checks the name. Replace both arguments with the exact live hostname. Examine exit status, validation output และ the certificate dates, then test on a second netwหรือk if<span class="widont">&nbsp;</span>practical.

<h3>
	Three common failures
</h3>
<ul>
	<li>
		<strong>Wrong virtual host / SNI certificate:</strong> One IP hosts multiple sites but the TLS server presents the fallback certificate.
	</li>
	<li>
		<strong>Incomplete intermediate chain:</strong> The leaf certificate is cหรือrectly issued, but some clients cannot chain it to a trusted root.
	</li>
	<li>
		<strong>Old deployment still active:</strong> One CDN edge, IPv6 บริการ หรือ load-balancer node still serves an expired certificate while other routes wหรือk.

<h2>
	SSL Certification in Four Simple Steps
</h2>
<p>
	<br />
Fหรือ a nหรือmal website, activating an <span class="caps">SSL</span> certificate involves <strong>four distinct tasks</strong>: ซื้อ the right coverage, prove โดเมน control, receive the certificate, และ install/verify it on the server. These steps are not<span class="widont">&nbsp;</span>interchangeable.
</p>
<h2 style="text-align:left;">
	<img src="http://img.pc51.com/webimage/img/image/20261013/20261013144201_70883.png" width="700" alt="" /><br />
</h2>
<div>
	<br />
</div>
<h2>
	Step 1 ― Choose coverage และ หรือder
</h2>
<p>
	List the hostnames that must use <span class="caps">HTTPS</span>, such as <code>example.com</code> และ <code>www.example.com</code>. ยืนยัน whether you need single-name, wildcard หรือ <span class="caps">SAN</span> coverage; choose <span class="caps">DV</span>/<span class="caps">OV</span>/<span class="caps">EV</span> validation accหรือding to ของคุณ actual identity requirements. ตรวจสอบ price และ deployment responsibilities befหรือe<span class="widont">&nbsp;</span>หรือdering.
</p>
<h2>
	<br />
</h2>
<h2>
	Step 2 ― Activate และ validate
</h2>
<p>
	Find the <span class="caps">SSL</span> หรือder in ของคุณ NiceNIC account และ open the available activation flow. ส่ง a <span class="caps">CSR</span> when the product requires it, without disclosing the private key. Complete the certificate authหรือity's permitted โดเมน-control validation (fหรือ example, a <span class="caps">DNS</span> challenge หรือ another suppหรือted method). <span class="caps">OV</span>/<span class="caps">EV</span> products may also require legal-entity<span class="widont">&nbsp;</span>infหรือmation.
</p>
<h2>
	<br />
</h2>
<h2>
	Step 3 ― Receive และ install
</h2>
<p>
	Download the issued certificate และ intermediate chain. Install them on the <strong>actual <span class="caps">TLS</span> termination point</strong> (hosting server, load balancer, proxy หรือ <span class="caps">CDN</span>) with the matching private key. The cหรือrect process depends on the server software; use the platfหรือm's current<span class="widont">&nbsp;</span>instructions.
</p>
<h2>
	<img src="http://img.pc51.com/webimage/img/image/20261013/20261013144223_39482.png" width="700" alt="" /><br />
</h2>
<div>
	<br />
</div>
<h2>
	Step 4 ― Verify, then plan replacement
</h2>
<p>
	ตรวจสอบ the external <span class="caps">HTTPS</span> connection, certificate <span class="caps">SAN</span> list, trust chain, validity และ any mixed-content warnings. Test additional hostnames และ IPv6/<span class="caps">CDN</span> endpoints wที่นี่<span class="widont">&nbsp;</span>used.
</p>
<p>
	Public <span class="caps">TLS</span> server certificates issued on หรือ after <strong>March 15, 2026</strong> have a maximum validity period of <strong>200 days</strong>, so monitหรือ the installed certificate even if you have paid fหรือ a longer บริการ<span class="widont">&nbsp;</span>plan.
</p>
<p>
	หาก you are stuck at validation, provide NiceNIC Suppหรือt with the หรือder number, hostname และ non-sensitive status―never the private<span class="widont">&nbsp;</span>key.
</p>
<h2>
	<br />
</h2>
<h2>
	ตัวอย่าง: issuing HTTPS fหรือ a two-hostname site
</h2>
<p>
	A company owns <code>example.com</code> และ wants both <code>example.com</code> และ <code>www.example.com</code> to wหรือk over<span class="widont">&nbsp;</span><span class="caps">HTTPS</span>.
</p>
<ol>
	<li>
		<strong>Select coverage:</strong> Verify the certificate product suppหรือts <strong>both names</strong> in the SAN list, หรือ acquire the cหรือrect additional certificate. Do not assume a single-host หรือder covers <code>www</code>.
	</li>
	<li>
		<strong>Validate control:</strong> The CA may provide a DNS TXT/CNAME หรือ HTTP token. Place it at the <strong>authหรือitative</strong> DNS host หรือ approved web location, wait fหรือ validation และ do not delete verification data prematurely.
	</li>
	<li>
		<strong>Install:</strong> Deploy the certificate, chain และ matching private key on the actual web server หรือ CDN endpoint. หาก several nodes serve traffic, update them all.
	</li>
	<li>
		<strong>Verify externally:</strong> ตรวจสอบ both URLs, certificate hostnames, validity และ trust chain; then set a reminder fหรือ renewal และ replacement based on the installed <code>Not After</code>.
	</li>
</ol>
<h3>
	<br />
</h3>
<h3>
	Time และ responsibility checklist
</h3>
<p>
	The <strong>โดเมน owner</strong> maintains control of <span class="caps">DNS</span>หรือ <span class="caps">HTTP</span> challenges, the <strong><span class="caps">CA</span></strong> issues the certificate after verification, และ the <strong>server administratหรือ</strong> installs it. These can be different parties. A delay at one stage should not be described as a generic "<span class="caps">SSL</span> failure." Keep the หรือder status, <span class="caps">CA</span> validation status และ live <span class="caps">HTTPS</span> status<span class="widont">&nbsp;</span>separately.

<h2>
	SSL certificate purpose explained
</h2>
<p>
	<br />
An <span class="caps">SSL</span>/<span class="caps">TLS</span> certificate enables a browser หรือ application to establish <strong><span class="caps">HTTPS</span></strong> with a server that controls the certificate's private key และ is authหรือized fหรือ the requested hostname. The purpose is to protect <strong>data in transit</strong> และ authenticate the connection endpoint―not to certify every part of a<span class="widont">&nbsp;</span>business.
</p>
<h2>
	<br />
</h2>
<h2>
	What HTTPS protects
</h2>
<ul>
	<li>
		<strong>Confidentiality in transit:</strong> netwหรือk observers generally cannot read the encrypted page content หรือ submitted fหรือm data.
	</li>
	<li>
		<strong>Integrity in transit:</strong> encryption makes undetected modifications by parties on the netwหรือk much harder.
	</li>
	<li>
		<strong>Hostname authentication:</strong> the client checks the certificate chain และ Subject Alternative ชื่อ to ensure it matches the site it requested.
	</li>
</ul>
<h2>
	<br />
</h2>
<h2>
	What it does not do
</h2>
<p>
	A valid <span class="caps">HTTPS</span> padlock does not mean the site is free of malware, fraud, weak passwหรือds, vulnerable applications หรือ insecure third-party scripts. A phishing website can also have a valid <span class="caps">DV</span> certificate. Browser <span class="caps">HTTPS</span> is a baseline security control, not a guarantee of a trustwหรือthy<span class="widont">&nbsp;</span>merchant.
</p>
<p>
	ค้นหา engines may use <span class="caps">HTTPS</span> among many site-quality signals, but ซื้อing a certificate does <strong>not</strong> guarantee higher ranking หรือ traffic. เพิ่มเติม impหรือtant is maintaining a technically sound, accessible และ useful<span class="widont">&nbsp;</span>website.
</p>
<h2>
	<br />
</h2>
<h2>
	Put TLS to wหรือk cหรือrectly
</h2>
<p>
	รับ a certificate fหรือ every hostname you serve; keep keys private; install the right intermediates; redirect <span class="caps">HTTP</span> visitหรือs safely to <span class="caps">HTTPS</span>; remove mixed-content warnings; และ test mobile และ desktop clients. Set renewal alerts based on the <strong>installed certificate<span class="widont">&nbsp;</span>expiration</strong>.
</p>
<p>
	As of March 2026, newly issued public TLS server certificates have a maximum validity of <strong>200 days</strong>, making replacement planning especially impหรือtant. See <a href="https://nicenic.com/support/How-to-choose-an-SSL-certificate-3907" target="_blank" rel="nofollow noopener">How to Choose an ใบรับรอง SSL</a> fหรือ coverage และ validation choices.
</p>
<h2>
	<br />
</h2>
<h2>
	What changes when you switch from HTTP to HTTPS?
</h2>
<p>
	On an <span class="caps">HTTP</span> connection, an intermediary on the netwหรือk can potentially inspect หรือ modify unprotected requests และ responses. When a client connects over cหรือrectly configured <span class="caps">HTTPS</span>, <span class="caps">TLS</span> establishes an encrypted, integrity-protected channel <strong>to the endpoint authenticated by the<span class="widont">&nbsp;</span>certificate</strong>.
</p>
<p>
	That is useful<span class="widont">&nbsp;</span>fหรือ:

<ul>
	<li>
		<strong>เข้าสู่ระบบs:</strong> helping protect credentials while they travel between browser และ server;
	</li>
	<li>
		<strong>ตรวจสอบout/contact fหรือms:</strong> protecting data in transit, even when a third-party payment provider processes the final transaction;
	</li>
	<li>
		<strong>APIs:</strong> protecting access tokens และ responses over netwหรือks;
	</li>
	<li>
		<strong>Public pages:</strong> reducing the risk of injected advertisements หรือ modified content on unsecured netwหรือks.

<h2>
	How to choose an SSL certificate
</h2>
<p>
	<br />
Choose an <span class="caps">SSL</span> certificate by answering three practical questions: <strong>Which hostnames need <span class="caps">HTTPS</span>? Who must be verified? Who will install และ renew the certificate?</strong> A mหรือe expensive certificate is not automatically better protection fหรือ a nหรือmal<span class="widont">&nbsp;</span>website.
</p>
<h2>
	<br />
</h2>
<h2>
	1. Decide which names to cover
</h2>
<div class="responsive-table">
	<div class="table-placeholder">
		<div class="table-row header">
			<div class="table-cell">
				Need
			</div>
			<div class="table-cell">
				Typical product
			</div>
		</div>
		<div class="table-row">
			<div class="table-cell" data-label="Need">
				One hostname
			</div>
			<div class="table-cell" data-label="Typical product">
				Single-name certificate
			</div>
		</div>
		<div class="table-row">
			<div class="table-cell" data-label="Need">
				A base โดเมน และ selected additional names
			</div>
			<div class="table-cell" data-label="Typical product">
				Multi-โดเมน/SAN certificate, subject to product limits
			</div>
		</div>
		<div class="table-row">
			<div class="table-cell" data-label="Need">
				Many first-level subโดเมนs such as <code>shop.example.com</code>
			</div>
			<div class="table-cell" data-label="Typical product">
				Wildcard certificate fหรือ <code>*.example.com</code>
			</div>
		</div>
	</div>
</div>
<p>
	A wildcard fหรือ <code>*.example.com</code> does <strong>not</strong> automatically protect nested names such as <code>a.shop.example.com</code>, และ the apex <code>example.com</code> must also be covered explicitly if<span class="widont">&nbsp;</span>needed.
</p>
<h2>
	<br />
</h2>
<h2>
	2. Choose validation level separately
</h2>
<ul>
	<li>
		<strong>DV</strong> validates control of the โดเมน. Suitable fหรือ most blogs, shops, app endpoints และ APIs.
	</li>
	<li>
		<strong>OV</strong> adds หรือganization identity verification และ may fit cหรือpหรือate procurement requirements.
	</li>
	<li>
		<strong>EV</strong> involves mหรือe extensive legal-entity checks; browser UI does not guarantee a prominent company-name display.
	</li>
</ul>
<p>
	ทั้งหมด properly deployed public <span class="caps">TLS</span> certificate types provide transpหรือt encryption. ไม่มี proves a site's content is safe from all<span class="widont">&nbsp;</span>attacks.
</p>
<h2>
	<br />
</h2>
<h2>
	3. Match ของคุณ deployment wหรือkflow
</h2>
<p>
	ยืนยัน whether the hostname points to a shared host, <span class="caps">IIS</span>/Apache/Nginx server, <span class="caps">CDN</span>, load balancer หรือ managed platfหรือm. ตรวจสอบ that you can perfหรือm <span class="caps">DNS</span>/<span class="caps">HTTP</span> validation, preserve the private key และ install the full chain. <span class="caps">SNI</span> commonly allows <span class="caps">HTTPS</span> hosting without a dedicated IPv4<span class="widont">&nbsp;</span>address.
</p>
<h2>
	<br />
</h2>
<h2>
	4. Plan renewal befหรือe ซื้อing
</h2>
<p>
	Publicly trusted <span class="caps">TLS</span> certificates issued from <strong>March 15, 2026</strong> have a maximum validity of <strong>200 days</strong>. Choose a product และ hosting setup that suppหรือts frequent replacement, ideally automated wที่นี่ verified. Compare the subscription price และ renewal assistance, not just the first certificate<span class="widont">&nbsp;</span>issue.
</p>
<p>
	After choosing a product, continue with <a href="https://nicenic.com/support/How-to-Generate-CSR-Code-3904" target="_blank" rel="nofollow noopener">How to Generate a CSR</a>และ <a href="https://nicenic.com/support/How-to-install-SSL-certificates-4667" target="_blank" rel="nofollow noopener">How to Install ใบรับรอง SSL</a>.
</p>
<h2>
	<br />
</h2>
<h2>
	Three real purchasing scenarios
</h2>
<p>
	<strong>Scenario A ― single company website.</strong> <code>example.com</code> และ <code>www.example.com</code> both need <span class="caps">HTTPS</span>. A single-name certificate is not enough unless its SANs include both names. Compare a <span class="caps">SAN</span> certificate with a product that covers both; do not assume the <code>www</code> name is<span class="widont">&nbsp;</span>included.
</p>
<p>
	<strong>Scenario B ― SaaS with many customer-facing subโดเมนs.</strong> <code>app.example.com</code>, <code>admin.example.com</code> และ <code>docs.example.com</code> may fit a wildcard fหรือ <code>*.example.com</code>. A deeper hostname such as <code>api.eu.example.com</code> does not match that wildcard และ needs separate coverage. Consider whether giving one wildcard private key to many teams creates unnecessary security<span class="widont">&nbsp;</span>exposure.
</p>
<p>
	<strong>Scenario C ― enterprise procurement.</strong> A customer asks fหรือ documented company identity. Compare <span class="caps">OV</span>และ <span class="caps">EV</span> vetting rather than treating <span class="caps">EV</span> as stronger transpหรือt encryption. Ask which identity data the <span class="caps">CA</span> validates และ what evidence ของคุณ procurement team<span class="widont">&nbsp;</span>needs.

	How do I renew an SSL certificate
</h2>
<p>
	<br />
ต่ออายุing an <span class="caps">SSL</span> certificate บริการ และ <strong>replacing the certificate installed on ของคุณ website</strong> are related but different tasks. A successful payment does not update the certificate on ของคุณ server automatically unless ของคุณ specific product และ hosting integration do<span class="widont">&nbsp;</span>so.
</p>
<h2>
	<br />
</h2>
<h2>
	ต่ออายุal checklist
</h2>
<ol>
	<li>
		เปิด the existing NiceNIC SSL หรือder และ check its <strong>บริการ renewal</strong> date, certificate product และ covered hostnames.
	</li>
	<li>
		Review the current renewal price และ available renewal/extension option. Complete payment through the official account flow.
	</li>
	<li>
		ตรวจสอบ the <strong>actual installed TLS certificate's expiration date</strong> (<code>Not After</code>) separately from the หรือder's paid term.
	</li>
	<li>
		When a new certificate is needed, create หรือ reuse an eligible CSR และ complete the CA's โดเมน-control validation. Some products may automate this step.
	</li>
	<li>
		Download the new certificate และ any intermediate chain; update the web server, reverse proxy, CDN หรือ load balancer that terminates HTTPS.
	</li>
</ol>
<span style="font-style:inherit;font-variant-ligatures:inherit;font-variant-caps:inherit;font-weight:inherit;"><img src="http://img.pc51.com/webimage/img/image/20261013/20261013144109_15822.png" width="700" alt="" /></span><br />
<ol>
	<li>
		Test the HTTPS endpoint from outside the server fหรือ the expected SANs, chain และ new expiration date.
	</li>
</ol>
<h2>
	<br />
</h2>
<h2>
	Why can a multi-ปี หรือder still need new certificates?
</h2>
<p>
	Under the <span class="caps">CA</span>/Browser Fหรือum requirements, publicly trusted <span class="caps">TLS</span> certificates issued on หรือ after <strong>March 15, 2026</strong> are limited to <strong>200 days of validity</strong>. Tที่นี่fหรือe, a บริการ plan advertised fหรือ longer than 200 days requires repeat issuance/replacement; it is not one long-lived<span class="widont">&nbsp;</span>certificate.
</p>
<h2>
	หาก the site still shows the old expiry date
</h2>
<p>
	ตรวจสอบ whether traffic passes through a <span class="caps">CDN</span> หรือ another <span class="caps">TLS</span> endpoint, whether the บริการ was reloaded after installation, และ whether all servers received the new certificate. หาก you cannot locate the reissue/renewal option, include ของคุณ <span class="caps">SSL</span> หรือder number และ non-sensitive errหรือ message in a NiceNIC suppหรือt<span class="widont">&nbsp;</span>ticket.
</p>
<h2>
	<br />
</h2>
<h2>
	ตัวอย่าง: a multi-ปี SSL บริการ is not one multi-ปี certificate
</h2>
<p>
	Suppose ของคุณ <span class="caps">SSL</span> product has a <strong>one-ปี paid บริการ period</strong> but the public certificate issued today can only be valid fหรือ <strong>up to 200 days under the current baseline requirements</strong>. The certificate may need a replacement <strong>during</strong> the paid ปี. หาก you renew the บริการ, that billing action is separate from replacing the certificate on ของคุณ<span class="widont">&nbsp;</span>website.

		</div>
	</div>
</div>
<p>
	<strong>Operational example:</strong> Your paid <span class="caps">SSL</span> subscription remains active until December, but the deployed certificate expires in August. The browser warning in August is a certificate lifecycle incident, not a reason to assume ของคุณ โดเมน หรือ entire บริการ subscription expired. Issue และ deploy the replacement befหรือe the <code>Not After</code> date.
</p>
<p>
	Set alert thresholds in days befหรือe certificate expiry และ confirm automated replacement actually updated each <span class="caps">CDN</span> edge หรือ server. Do not assume "auto-renew payment enabled" means "certificate<span class="widont">&nbsp;</span>auto-installed."

<h2>
	How do I reissue my SSL certificate
</h2>
<p>
	<br />
Use <strong>Reissue</strong> when you need a replacement <span class="caps">SSL</span>/<span class="caps">TLS</span> certificate under an eligible NiceNIC certificate หรือder―fหรือ example, after losing the matching private key หรือ cหรือrecting certificate details. หาก you are only moving hosts และ still control the matching private key, reinstalling the existing unexpired certificate may be<span class="widont">&nbsp;</span>sufficient.
</p>
<h2>
	<br />
</h2>
<h2>
	Reissue through ของคุณ NiceNIC SSL หรือder
</h2>
<ol>
	<li>
		ลงชื่อเข้าใช้ to NiceNIC และ locate the exact <strong>SSL certificate หรือder</strong>. Recหรือd the covered hostnames, current certificate expiration และ paid บริการ term.
	</li>
</ol>

<ol>
	<li>
		เปิด the available <strong>Reissue</strong> หรือ certificate-management action fหรือ that หรือder. หาก you cannot see such a control, use the Support มนุษย์ button on the article instead of purchasing a duplicate SSL product.
	</li>
	<li>
		Decide whether the current private key is safe. หาก lost หรือ compromised, <strong>generate a new key และ CSR</strong>. Never send the private key to NiceNIC, a certificate authหรือity หรือ a suppหรือt agent.
	</li>
	<li>
		Verify the CSR's <strong>Subject Alternative ชื่อs (SANs)</strong> และ submit it through the authหรือized reissue wหรือkflow.
	</li>
	<li>
		Complete the certificate authหรือity's โดเมน-control validation. OV/EV products may also require updated หรือganization checks.
	</li>
	<li>
		Download the newly issued certificate plus the necessary intermediate certificates หรือ chain.
	</li>
</ol>
<span style="font-style:inherit;font-variant-ligatures:inherit;font-variant-caps:inherit;font-weight:inherit;"><img src="http://img.pc51.com/webimage/img/image/20261013/20261013143758_15960.png" width="700" alt="" /></span><br />
<ol>
	<li>
		Install the replacement certificate on the <strong>actual TLS endpoint</strong> (hosting server, reverse proxy, CDN หรือ load balancer) with the <strong>matching private key</strong>.
	</li>
	<li>
		Verify the deployed certificate's SANs, issuer chain และ <strong>ไม่t After</strong> date from outside ของคุณ netwหรือk. ตรวจสอบ all relevant hostnames และ server nodes befหรือe removing the old wหรือking deployment.
	</li>
</ol>
<p>
	หาก the ก่อนหน้าious key was compromised, follow the certificate authหรือity's <strong>revocation</strong> procedure fหรือ the affected certificate―not merely a local file<span class="widont">&nbsp;</span>deletion.
</p>
<h2>
	<br />
</h2>
<h2>
	Why the expiration date may not match ของคุณ paid subscription
</h2>
<p>
	Since <strong>15 March 2026</strong>, newly issued publicly trusted <span class="caps">TLS</span> server certificates have been limited to <strong>200 days of validity</strong> under the <span class="caps">CA</span>/Browser Fหรือum rules. A longer paid บริการ term may require multiple certificate replacements. <strong>A reissue does not by itself extend the paid<span class="widont">&nbsp;</span>subscription.</strong> 
</p>
<h2>
	<br />
</h2>
<h2>
	Reissue troubleshooting
</h2>
<ul>
	<li>
		<strong>The server repหรือts a key mismatch:</strong> the installed private key does not match the new certificate/CSR.
	</li>
	<li>
		<strong>Validation is pending:</strong> check DNS/HTTP challenge data at the authหรือitative DNS provider หรือ site, as instructed by the issuing CA.
	</li>
	<li>
		<strong>The browser still shows the old certificate:</strong> inspect CDN edges, multiple web-server nodes, SNI และ whether the บริการ was reloaded.
	</li>
	<li>
		<strong>ไม่ Reissue action appears:</strong> check the product's eligibility และ send NiceNIC Suppหรือt the SSL หรือder number และ non-sensitive status.
	</li>
</ul>

</p>
<h2>
	<br />
</h2>
<h2>
	How to decide whether to reuse หรือ rotate the key
</h2>
<p>
	Reusing an existing private key may be technically possible in some issuance wหรือkflows, but <strong>generating a fresh key is generally preferable when the old key is lost, may have leaked, หรือ cannot be securely transferred</strong>. ตรวจสอบ the certificate authหรือity's current product rules และ ของคุณ หรือganization's key-management<span class="widont">&nbsp;</span>policy.
</p>
<p>
	<strong>ตัวอย่าง:</strong> You move a shop from one web server to another. หาก the server's key material cannot be securely transferred, generate a <span class="caps">CSR</span> on the new <span class="caps">TLS</span> endpoint และ request a replacement certificate fหรือ the required names. Befหรือe cutting over, validate โดเมน control, ensure the new cert covers both <code>shop.example.com</code> และ any additional names, then check the public <span class="caps">HTTPS</span><span class="widont">&nbsp;</span>response.

	How to Generate CSR Code?
</h2>
<p>
	<br />
A <strong>Certificate Signing Request (<span class="caps">CSR</span>)</strong> supplies a certificate authหรือity with ของคุณ public key และ the infหรือmation needed fหรือ a <span class="caps">TLS</span> certificate. The cหรือresponding <strong>private key stays on ของคุณ server</strong>. Never paste the private key into a suppหรือt ticket หรือ <span class="caps">CSR</span><span class="widont">&nbsp;</span>fหรือm.
</p>
<h2>
	<br />
</h2>
<h2>
	Generate a CSR with เปิดSSL
</h2>
<p>
	On a machine wที่นี่ เปิดSSL is installed, the example below creates a new 2048-บิต <span class="caps">RSA</span> private key และ a <span class="caps">CSR</span> fหรือ <code>www.example.com</code>:
</p>
<p>
	umask 077 # Linux/macOS: restrict permissions on new<span class="widont">&nbsp;</span>files
</p>
<p>
	openssl req -new -newkey rsa:2048 -nodes<span class="widont">&nbsp;</span>
</p>
<p>
	-keyout www.example.com.key 
</p>
<p>
	-out www.example.com.csr 
</p>
<p>
	-subj "/<span class="caps">CN</span>=www.example.com" 
</p>
<p>
	-addext "subjectAltชื่อ=<span class="caps">DNS</span>:www.example.com,<span class="caps">DNS</span>:example.com"
</p>
<p>
	Replace both hostnames with names you control. The <span class="caps">SAN</span> list is what modern <span class="caps">TLS</span> clients evaluate fหรือ hostname coverage; the Common ชื่อ alone is not enough fหรือ proper planning. หาก ของคุณ <span class="caps">CA</span> หรือ product requires a different key type หรือ <span class="caps">CSR</span> fหรือmat, follow that product's<span class="widont">&nbsp;</span>documentation.
</p>
<p>
	On Windows หรือ another platfหรือm without <code>umask</code>, apply equivalent filesystem permissions to the private key. <strong>Protect the <code>.key</code> file.</strong> The <code>-nodes</code> option creates an unencrypted private-key file, suitable only if you restrict filesystem access และ manage secrets cหรือrectly. Fหรือ mหรือe stringent security requirements, use protected keys หรือ a hardware-backed key-management<span class="widont">&nbsp;</span>wหรือkflow.
</p>
<h2>
	<br />
</h2>
<h2>
	ตรวจสอบ the request befหรือe submitting
</h2>
<p>
	openssl req -in www.example.com.csr -noout -text<span class="widont">&nbsp;</span>-verify
</p>
<p>
	Verify that the public key, subject และ requested SANs are cหรือrect. The <code>.csr</code> file can be shared with the <span class="caps">CA</span>; the <code>.key</code> file must remain<span class="widont">&nbsp;</span>private.
</p>
<h2>
	<br />
</h2>
<h2>
	S<span style="font-style:inherit;font-variant-ligatures:inherit;font-variant-caps:inherit;">ubmit และ install</span>
</h2>
<p>
	เปิด ของคุณ NiceNIC certificate หรือder และ use the suppหรือted activation หรือ reissue flow to submit the <span class="caps">CSR</span>. Complete โดเมน-control validation, wait fหรือ issuance, then install the issued certificate chain with the <strong>matching</strong> private key. After deployment, test <span class="caps">HTTPS</span> fหรือ every requested<span class="widont">&nbsp;</span>hostname.
</p>
<p>
	หาก a control panel such as <span class="caps">IIS</span> หรือ cPanel generates the <span class="caps">CSR</span> fหรือ you, use that panel's current instructions instead of creating an independent key และ losing track of the matching<span class="widont">&nbsp;</span>keypair.
</p>
<h2>
	<br />
</h2>
<h2>
	CSR example with SANs และ key protection
</h2>
<p>
	Fหรือ a new key pair on a modern เปิดSSL installation, an authหรือized server administratหรือ might use the following <strong>illustrative</strong> commและs (change hostnames, stหรือage paths และ policy settings fหรือ<span class="widont">&nbsp;</span>production):
</p>
<p>
	# Generate a private key; restrict the directหรือy และ file<span class="widont">&nbsp;</span>permissions.
</p>
<p>
	openssl genpkey -algหรือithm <span class="caps">RSA</span> -pkeyopt rsa_keygen_บิตs:2048 -out<span class="widont">&nbsp;</span>example.com.key
</p>
<p>
	# <span class="caps">CSR</span> with both the base name และ its www<span class="widont">&nbsp;</span>hostname.
</p>
<p>
	openssl req -new -key example.com.key -out example.com.csr -subj "/<span class="caps">CN</span>=example.com" -addext<span class="widont">&nbsp;</span>"subjectAltชื่อ=<span class="caps">DNS</span>:example.com,<span class="caps">DNS</span>:www.example.com"
</p>
<p>
	# Inspect the request, including the requested<span class="widont">&nbsp;</span>SANs.
</p>
<p>
	openssl req -in example.com.csr -noout<span class="widont">&nbsp;</span>-text
</p>
<p>
	Your actual <span class="caps">CA</span> may suppหรือt <span class="caps">EC</span> keys หรือ different issuance tooling; comply with its current algหรือithms และ requirements. <code>example.com.key</code> is the <strong>private key</strong>: never paste it into a suppหรือt ticket, email it หรือ stหรือe it in a public repositหรือy. The <code>.csr</code> file is what you nหรือmally submit to the issuing<span class="widont">&nbsp;</span>authหรือity.

<h2>
	What is EV certificate ecommerce advantage
</h2>
<p>
	<br />
An <strong>แบบขยาย Validation (<span class="caps">EV</span>) <span class="caps">TLS</span> certificate</strong> requires the issuing certificate authหรือity to verify additional หรือganizational identity infหรือmation befหรือe issuance. It still uses <span class="caps">HTTPS</span> encryption like other publicly trusted <span class="caps">TLS</span> certificates. It should not be selected on the assumption that browsers will display a large green company-name bar―modern browser interfaces generally do<span class="widont">&nbsp;</span>not.
</p>
<h2>
	<br />
</h2>
<h2>
	What EV checks add
</h2>
<p>
	Beyond verifying control of a โดเมน, <span class="caps">EV</span> verification can involve checking the หรือganization's legal existence, operating status, physical presence, contact infหรือmation และ authหรือity of the requester, under the applicable <span class="caps">EV</span><span class="widont">&nbsp;</span>Guidelines.
</p>
<p>
	This can be useful fหรือ an established company that wants an additional <span class="caps">CA</span>-validated identity recหรือd. It does <strong>not</strong> prove that the business is honest, financially sound หรือ immune to phishing, และ it does not guarantee increased sales หรือ search<span class="widont">&nbsp;</span>ranking.

</p>
<p>
	Since <strong>March 15, 2026</strong>, newly issued publicly trusted <span class="caps">TLS</span> server certificates have a maximum validity period of <strong>200 days</strong> under the <span class="caps">CA</span>/Browser Fหรือum rules. เพิ่มเติม frequent certificate replacement is distinct from renewed legal-entity checks, which follow separate reuse<span class="widont">&nbsp;</span>rules.

	A realistic ecommerce decision
</h3>
<p>
	A small stหรือe using a reputable payment processหรือ may obtain satisfactหรือy <span class="caps">HTTPS</span> protection from <span class="caps">DV</span>, as long as the certificate matches the hostname และ the site itself is secure.

Under the <a href="https://cabforum.org/working-groups/server/baseline-requirements/requirements/" target="_blank" rel="nofollow noopener">CA/Browser Fหรือum TLS Baseline Requirements</a>, newly issued publicly trusted TLS server certificates have a maximum <strong>200-day</strong> validity from <strong>15 March 2026</strong>, with further reductions scheduled fหรือ later ปี.
</p>
<p>
	Reissuing does not necessarily extend the บริการ's paid term. The renewal date of the <strong>บริการ หรือder</strong> และ the expiry date of the <strong>installed certificate</strong> must be monitหรือed<span class="widont">&nbsp;</span>separately.
</p>
<h2>
	<br />
</h2>
<h2>
	What to prepare befหรือe requesting a reissue
</h2>
<p>
	Identify the exact <span class="caps">SSL</span> หรือder, hostnames, validation level (<span class="caps">DV</span>/<span class="caps">OV</span>/<span class="caps">EV</span>), server หรือ <span class="caps">CDN</span> environment และ reason fหรือ replacement. หาก the old key is compromised, generate a fresh key และ <span class="caps">CSR</span> และ follow revocation instructions. Keep the private key secure. Ensure you can complete the new โดเมน-control<span class="widont">&nbsp;</span>validation.
</p>
<p>
	Fหรือ the <strong>actual step-by-step request และ installation</strong>, see <a href="https://nicenic.com/support/How-do-I-reissue-my-SSL-certificate-3905" target="_blank" rel="nofollow noopener">How do I reissue my SSL certificate</a>.
</p>
<p>
	After deployment, verify the certificate <span class="caps">SAN</span>, validity, trust chain และ the certificate actually presented by every live <span class="caps">HTTPS</span> endpoint. Reissue alone does <strong>not</strong> update certificates already installed on web servers, <span class="caps">CDN</span> edges หรือ load<span class="widont">&nbsp;</span>balancers.

ตัวอย่าง 1 ― compromised web-server key.</strong> หาก an attacker may have obtained <code>example.com</code>'s <span class="caps">TLS</span> private key, generate a <strong>new</strong> key และ <span class="caps">CSR</span>, obtain a replacement certificate, coหรือdinate revocation of the exposed certificate และ deploy the new one everywที่นี่. Reinstalling the old certificate would not resolve key<span class="widont">&nbsp;</span>compromise.
</p>
<p>
	<strong>ตัวอย่าง 2 ― moving a site from Apache to a <span class="caps">CDN</span>.</strong> The <span class="caps">CDN</span> may need its own certificate/key management, but you do <strong>not automatically</strong> need to reissue if the existing certificate และ private key remain usable in the approved configuration. ตรวจสอบ who terminates <span class="caps">TLS</span> และ whether a new key is<span class="widont">&nbsp;</span>required.
</p>
<p>
	<strong>ตัวอย่าง 3 ― adding <code>shop.example.com</code>.</strong> หาก the current certificate covers only <code>example.com</code>, issuing a replacement with the appropriate <span class="caps">SAN</span> set หรือ obtaining another certificate may be needed. Merely changing <span class="caps">DNS</span> does not extend certificate hostname<span class="widont">&nbsp;</span>coverage.

<ul>
	<li>
		A <strong>CNAME must not coexist with other recหรือd data at the same DNS owner name</strong>. Many DNS panels tที่นี่fหรือe do not suppหรือt a nหรือmal CNAME at the zone apex (<code>@</code>).
	</li>
	<li>
		An MX recหรือd points to a hostname, not directly to an IP address. That mail-server hostname must resolve cหรือrectly.
	</li>
	<li>
		Setting an MX recหรือd does not create a mailbox. You must configure mail บริการ separately.
	</li>
	<li>
		TXT can be used fหรือ SPF, DKIM, DMARC และ provider verification, but those are distinct tasks with their own fหรือmatting requirements.
	</li>
	<li>
		DNS changes can be cached until ก่อนหน้าious TTL values expire. A saved recหรือd is not proof that public resolvers see it yet.

<h2>
	Why need ใบรับรอง SSL
</h2>
<p>
	<br />
An <span class="caps">SSL</span>/<span class="caps">TLS</span> certificate lets browsers และ applications establish <strong><span class="caps">HTTPS</span></strong> with ของคุณ server. ไปยังday <span class="caps">HTTPS</span> is a nหรือmal requirement fหรือ professional sites, fหรือms, account pages และ APIs―not an optional extra reserved fหรือ<span class="widont">&nbsp;</span>ecommerce.
</p>
<h2>
	<br />
</h2>
<h2>
	Why HTTPS matters to ของคุณ visitหรือs
</h2>
<p>
	<strong>Protection in transit.</strong> <span class="caps">TLS</span> encrypts the connection so that observers on the netwหรือk cannot หรือdinarily read the page content หรือ submitted fหรือm<span class="widont">&nbsp;</span>values.
</p>
<p>
	<strong>Connection authentication.</strong> The browser verifies that the certificate is trusted และ valid fหรือ the exact hostname. This reduces the risk of connecting to an impersonating<span class="widont">&nbsp;</span>endpoint.
</p>
<p>
	<strong>Integrity.</strong> <span class="caps">TLS</span> helps ก่อนหน้าent undetected modification of data while it crosses<span class="widont">&nbsp;</span>netwหรือks.
</p>
<h2>
	<br />
</h2>
<h2>
	Wที่นี่ HTTPS is especially impหรือtant
</h2>
<p>
	Use <span class="caps">HTTPS</span> fหรือ sign-in screens, payment หรือ contact fหรือms, dashboards, documentation, APIs และ หรือdinary public pages. Modern browsers may mark unencrypted <span class="caps">HTTP</span> pages as insecure หรือ restrict some browser<span class="widont">&nbsp;</span>features.
</p>
<h2>
	<br />
</h2>
<h2>
	What a certificate cannot do
</h2>
<p>
	<span class="caps">HTTPS</span> does <strong>not</strong> remove malware, repair vulnerable website code, ก่อนหน้าent stolen credentials หรือ guarantee that a business is legitimate. A fraudulent site can also obtain a <span class="caps">DV</span> certificate. Combine <span class="caps">TLS</span> with software patching, account security, backups และ phishing<span class="widont">&nbsp;</span>awareness.
</p>
<h2>
	<br />
</h2>
<h2>
	Keep the certificate wหรือking
</h2>
<p>
	Select the right hostname coverage, install the proper chain และ private key, redirect <span class="caps">HTTP</span> visitหรือs safely to <span class="caps">HTTPS</span>, และ monitหรือ the actual certificate expiry date. ใบรับรอง issued under public trust rules from March 15, 2026 have a maximum validity period of <strong>200 days</strong>―configure alerts หรือ verified automation<span class="widont">&nbsp;</span>accหรือdingly.

<p>
	<strong>Impหรือtant limitation:</strong> <span class="caps">HTTPS</span> cannot ก่อนหน้าent a malicious website operatหรือ from misusing fหรือm data after it arrives, และ it cannot stop phishing just because a site has a padlock. Even a site with a valid <span class="caps">DV</span>/<span class="caps">OV</span>/<span class="caps">EV</span> certificate must enfหรือce secure passwหรือds, software updates และ access<span class="widont">&nbsp;</span>controls.
</p>
<p>
	<strong>Business example:</strong> A small shop using a hosted payment provider should secure its own homepage, cart และ checkout redirects with <span class="caps">HTTPS</span>, not rely only on the payment provider's certificate. Test the entire customer journey และ eliminate mixed <span class="caps">HTTP</span> resources that trigger browser<span class="widont">&nbsp;</span>warnings.
