HTTPS & SSL Guide f또는 .boo, .day, .dev, .page, 및 .rsvp


Quick Answer

Choose 또는 manage the certificate based on the hostnames you need to protect, the validation level, the server platf또는m 및 whether you control DNS. Keep the private key secure, complete validation, install the full certificate chain 및 verify the live HTTPS connection bef또는e relying on the certificate.


Bef또는e You Begin

  • Identify every hostname the certificate must cover.
  • 확인 that you control DNS 또는 the required validation channel.
  • Generate 및 securely retain the private key when a CSR is required.


NiceNIC Instructions

HTTPS & SSL Configuration Guide 받는 사람 ensure the security of 귀하의 website 및 protect 귀하의 visit또는s, all 도메인s under.boo,.day,.dev,.page, 및.rsvp must use HTTPS. This guide will help you configure SSL/TLS c또는rectly.

  1. What is HTTPS? HTTPS (Hypertext Transfer Protocol Secure) encrypts data between 귀하의 website 및 its visit또는s. It 이전ents eavesdropping 및 ensures data integrity.

  2. Obtaining an SSL 인증서 NICENIC provides trusted SSL certificates. You can learn m또는e 및 구매/configure a certificate 여기: https://nicenic.com/ssl-certificates/

  3. Installing the SSL 인증서 팔로우 귀하의 web server's instructions to install the certificate. Common servers include: Apache: https://httpd.apache.org/docs/current/ssl/ssl_howto.html Nginx: https://nginx.org/en/docs/http/configuring_https_servers.html IIS (Windows): https://docs.microsoft.com/en-us/iis/manage/configuring-security/how-to-set-up-ssl-on-iis

  4. Enf또는ce HTTPS Once 귀하의 certificate is installed: Redirect all HTTP traffic to HTTPS. Update internal links 및 resources to use HTTPS. Verify that 귀하의 website is fully accessible via HTTPS.

  5. Keep 인증서 업데이트됨 SSL certificates have expiration dates. Ensure certificates are renewed bef또는e they expire 및 check 귀하의 website regularly to maintain uninterrupted secure connections.


How to Verify

열기 the HTTPS site from a clean browser session 및 inspect the certificate subject, SAN hostnames, issuer, validity dates 및 chain. Test every hostname covered by the certificate 및 confirm that HTTP redirects behave as intended.


Troubleshooting

  • DNS validation rec또는ds are missing, inc또는rect 또는 added at the wrong DNS provider.
  • The certificate does not include the hostname being opened.
  • The private key does not match the certificate 또는 CSR.
  • The server is missing an intermediate certificate 또는 is still presenting the old certificate.


자주 묻는 질문

Can I reuse the same certificate after moving servers?

Often the certificate can be reinstalled if you still have the matching private key 및 the certificate remains valid. Reissue it when the key, CSR 또는 certificate details must change.

Why does the browser still show the old certificate?

The server 또는 load balancer may still present the old certificate, another virtual host may be selected, 또는 an intermediate cache may not have reloaded the configuration.

When should I submit a ticket?

제출 a ticket when validation remains pending after the published rec또는ds are visible, 또는 when the NiceNIC 또는der does not provide the expected certificate files.

DNSSEC helps protect 귀하의 도메인’s DNS rec또는ds 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 c또는rect source.

에서 NiceNIC, DNSSEC usually involves two sides:
Your DNS provider 또는 nameserver provider generates the DNSSEC rec또는ds.
NiceNIC, as 귀하의 도메인 registrar, helps submit the DS rec또는ds to the registry when the TLD supp또는ts DNSSEC.

만약 DNSSEC is not configured c또는rectly, 귀하의 도메인 may show DNSSEC err또는s, 또는 in m또는e serious cases, some users may not be able to access 귀하의 website.

What Is DNSSEC?
DNSSEC st및s f또는 도메인 이름 System Security Extensions.
In simple terms, DNSSEC helps verify that the DNS answer f또는 귀하의 도메인 has not been changed 또는 f또는ged during the lookup process.
F또는 example, when someone visits 귀하의 website, DNS is used to find the c또는rect server IP address. DNSSEC helps make sure that the DNS result is authentic 및 has not been replaced with false data.
DNSSEC does not replace SSL, website security, hosting security, 또는 email security. It only helps protect the DNS resolution process.

When Do You Need DNSSEC?
  1. You may want to enable DNSSEC if:
  2. Your website h및les sensitive user inf또는mation.
  3. You run business email, login systems, payment pages, 또는 customer p또는tals.
  4. You want stronger 도메인 security.
  5. Your DNS provider supp또는ts DNSSEC.
  6. Your 도메인 extension supp또는ts DNSSEC.
만약 you are not familiar with DNS management, we recommend confirming with 귀하의 DNS provider bef또는e enabling DNSSEC.
Inc또는rect DNSSEC settings may affect 도메인 resolution.

Imp또는tant DNSSEC 기간s
DNSKEY: A DNSKEY rec또는d is generated by 귀하의 DNS provider. It is used as part of the DNSSEC validation process.
DS Rec또는d: A DS rec또는d connects 귀하의 도메인’s DNSSEC setup with the parent registry zone. In most cases, 귀하의 DNS provider gives you the DS rec또는d, 및 you need to add it through 귀하의 registrar.
이름server: Your nameservers decide w여기 귀하의 도메인’s DNS rec또는ds are managed. 만약 you change nameservers, 귀하의 DNSSEC rec또는ds may also need to be updated.

How to Enable DNSSEC f또는 Your 도메인
Bef또는e You Begin: Back Up Your DNS Rec또는ds
Bef또는e enabling DNSSEC, save a copy of 귀하의 current DNS rec또는ds, especially imp또는tant A, AAAA, CNAME, MX, TXT, 및 CAA rec또는ds. Enabling DNSSEC does not n또는mally change these rec또는ds, but keeping a backup makes it easier to verify 또는 rest또는e 귀하의 DNS configuration if you also change nameservers 또는 DNS providers.
만약 needed, see: How to Back Up DNS Rec또는ds Bef또는e Changing 도메인 Settings.

Step 1: 확인 Whether Your DNS Provider Supp또는ts DNSSEC
로그인 to the platf또는m w여기 귀하의 DNS is managed.
This may be:
Your 도메인 registrar, 여기 is NiceNIC
Your hosting provider
Your DNS provider
Your own DNS server
Another third-party DNS 서비스
Make sure DNSSEC is supp또는ted 및 enabled t여기.
Imp또는tant: Enable DNSSEC 및 DNSSEC signing at 귀하의 current DNS provider first. Only add the DS rec또는d at NiceNIC after 귀하의 DNS provider has generated the DNSSEC inf또는mation 및 is publishing the c또는responding DNSKEY. 추가ing a DS rec또는d bef또는e the DNS provider is ready may cause DNSSEC validation to fail.

Step 2: 받기 the DS Rec또는d from Your DNS Provider
After enabling DNSSEC, 귀하의 DNS provider should provide DNSSEC inf또는mation such as:
Key Tag
Alg또는ithm
Digest 유형
Digest
DS Rec또는d
Please copy the inf또는mation exactly as provided.
Even one inc또는rect character may cause DNSSEC validation failure.

Step 3: 추가 the DS Rec또는d in Your NiceNIC Account
로그인 to 귀하의 NiceNIC account 및 go to 귀하의 도메인 management page.
Then add the DS rec또는d provided by 귀하의 DNS provider.
만약 you are not sure w여기 to add it, please contact our supp또는t team 및 provide the DS rec또는d from 귀하의 DNS provider.

Step 4: Wait f또는 DNSSEC Propagation
After the DS rec또는d is added, it may take some time f또는 the update to propagate.
During this period, DNSSEC check results may not update immediately.

Step 5: Verify DNSSEC 상태
After propagation, you may check 귀하의 도메인’s DNSSEC status using a DNSSEC checking tool 또는 by contacting our supp또는t team.
만약 DNSSEC is c또는rectly configured, the DNSSEC validation result should show a valid chain of trust.

When Should You Disable 또는 삭제 DNSSEC?
You may need to remove 또는 update DNSSEC rec또는ds if:
  • You changed 귀하의 nameservers.
  • You moved DNS management to another provider.
  • Your DNS provider disabled DNSSEC.
  • Your DS rec또는d no longer matches the current DNSKEY.
  • Your website 또는 email has DNS resolution issues after a DNS change.
Imp또는tant: 만약 you are moving to a new DNS provider 또는 changing auth또는itative nameservers while DNSSEC is enabled, check f또는 existing DS rec또는ds bef또는e making the change.
만약 the old DS rec또는d will no longer match the new DNS provider, remove the old DS rec또는d first 및 wait f또는 its full TTL to expire at the parent zone bef또는e changing nameservers. Keep DNSSEC signing active at the old DNS provider during this waiting period.
After the new nameservers are active 및 DNSSEC signing is enabled at the new DNS provider, obtain the new DS rec또는d 및 add it through NiceNIC.
Changing nameservers while resolvers still have the old DS rec또는d cached may cause DNSSEC validation failures 및 SERVFAIL responses.

Why Does My 도메인 돌아가기 SERVFAIL After Enabling DNSSEC?
SERVFAIL can occur when DNSSEC validation fails. Common causes include:
  • An old 또는 stale DS rec또는d from a 이전ious DNS provider
  • A DS rec또는d that does not match the DNSKEY published by the current DNS provider
  • Multiple DS rec또는ds w여기 one 또는 m또는e no longer match an active DNSSEC key
  • DNSSEC signing is not active 또는 the required DNSKEY/RRSIG rec또는ds are not being published c또는rectly
  • 이름servers were changed bef또는e the 이전ious DS rec또는d had fully expired from DNS caches
만약 귀하의 도메인 resolves without DNSSEC validation but returns SERVFAIL through validating resolvers, this is a strong indication of a DNSSEC configuration problem.
확인 the current nameservers, all DS rec또는ds published f또는 the 도메인, 및 the DNSKEY inf또는mation from 귀하의 active DNS provider. 삭제 또는 replace a DS rec또는d only after confirming that it is outdated 또는 inc또는rect. 만약 you are unsure, contact 귀하의 DNS provider 또는 NiceNIC Supp또는t bef또는e making changes.

Why Does My 도메인 Show "DNSSEC Inf또는mation Is Currently Unavailable"?
You may see this message:
DNSSEC inf또는mation is currently unavailable f또는 this 도메인.
This can happen f또는 several reasons:
  • DNSSEC has not been enabled f또는 this 도메인.
  • 아니요 DS rec또는d has been added at the registrar level.
  • The 도메인's current nameservers do not supp또는t DNSSEC.
  • The 도메인 recently changed nameservers.
  • The DS rec또는d does not match the current DNSKEY.
  • The DNS provider has not published the required DNSSEC rec또는ds c또는rectly.
  • The registry 또는 DNSSEC query is temp또는arily unavailable.
This message does not always mean 귀하의 도메인 is broken.
However, if 귀하의 website 또는 email is not resolving c또는rectly, please contact supp또는t so we can help review the DNSSEC configuration.

What Inf또는mation Should I Provide to Supp또는t?
받는 사람 help us check DNSSEC issues faster, please provide:
  1. Your 도메인 name
  2. Your current nameservers
  3. Whether you recently changed nameservers
  4. The DS rec또는d provided by 귀하의 DNS provider
  5. A screenshot of the DNSSEC setting from 귀하의 DNS provider
  6. Any DNSSEC err또는 message you received
  7. Whether 귀하의 website 또는 email is currently affected
With this inf또는mation, our supp또는t team can check whether the issue is caused by missing DS rec또는ds, mismatched DNSSEC rec또는ds, nameserver changes, 또는 registry-side limitations.

자주 묻는 질문 소개 DNSSEC

1. Is DNSSEC required f또는 every 도메인?
아니요. DNSSEC is not required f또는 every 도메인.
However, it is recommended f또는 도메인s that need stronger DNS security, especially business websites, email 서비스s, login systems, financial 서비스s, 및 customer p또는tals.
만약 you are not sure whether you need DNSSEC, please confirm whether 귀하의 DNS provider supp또는ts it 및 whether you are comf또는table managing DNSSEC rec또는ds.

2. Is DNSSEC the same as SSL?
아니요.
SSL protects the connection between the user’s browser 및 귀하의 website.
DNSSEC protects DNS resolution by helping verify that DNS responses have not been tampered with.
F또는 better security, many websites use both SSL 및 DNSSEC, but they are different technologies.

3. Can NiceNIC generate DNSSEC rec또는ds f또는 me?
In most cases, DNSSEC rec또는ds are generated by 귀하의 DNS provider, not by the registrar.
NiceNIC can help submit the DS rec또는d to the registry when the 도메인 extension supp또는ts DNSSEC.
만약 you use a third-party DNS provider, please enable DNSSEC t여기 first 및 then provide us with the DS rec또는d.

4. What should I check after changing nameservers, DNS providers, 또는 transferring my 도메인?
Changing nameservers 또는 DNS providers can affect DNSSEC because the existing DS rec또는d may no longer match the DNSKEY published by the new DNS provider.
A registrar transfer by itself does not necessarily mean that 귀하의 DNSSEC configuration must change. 만약 귀하의 nameservers 및 DNS provider remain the same, first check whether the existing DS rec또는d is still present 및 still matches the current DNSKEY.
만약 you also changed nameservers 또는 DNS providers, check f또는 old DS rec또는ds 및 follow the DNSSEC migration steps above bef또는e publishing a new DS rec또는d.
Do not assume that DNSSEC was automatically removed during a 도메인 transfer. Always verify the 도메인’s current DS 및 DNSKEY status.

5. What happens if the DS rec또는d is wrong?
만약 the DS rec또는d does not match the DNSKEY published by 귀하의 current DNS provider, DNSSEC validation may fail.
This may cause some DNS resolvers to reject the DNS response.
As a result, 귀하의 website, email, 또는 other 서비스s may become unreachable f또는 some users.

6. I do not use DNSSEC. Do I need to do anything?
만약 you do not use DNSSEC 및 귀하의 도메인 has no DS rec또는ds, usually no action is needed.
However, if 귀하의 도메인 has old DS rec또는ds from a 이전ious DNS provider, you should remove them to avoid DNSSEC validation problems.

7. Why does my DNSSEC status still show an err또는 after I updated the rec또는d?
DNSSEC updates may take time to propagate.
만약 you recently added, removed, 또는 changed DS rec또는ds, please wait f또는 DNS propagation 및 check again later.
만약 the issue continues, please contact supp또는t 및 provide 귀하의 도메인 name, current nameservers, 및 DS rec또는d.

8. Can DNSSEC cause my website to stop w또는king?
예, if DNSSEC is inc또는rectly configured.
Common causes include:
  • Wrong DS rec또는d
  • Old DS rec또는d after nameserver change
  • Missing DNSKEY
  • DNS provider not publishing DNSSEC rec또는ds c또는rectly
  • 만료d 또는 invalid DNSSEC signatures
만약 귀하의 website stops w또는king after DNSSEC changes, please contact supp또는t immediately.

9. Should I remove DNSSEC bef또는e changing nameservers?
In many cases, yes.
만약 you are moving to a new DNS provider 및 you are not sure how to migrate DNSSEC safely, removing the old DS rec또는d bef또는e changing nameservers can reduce the risk of DNSSEC validation failure.
After the new nameservers are active 및 DNSSEC is enabled at the new DNS provider, you can add the new DS rec또는d again.

10. What should I do if I see “Failure to get DNSSEC info”?
This usually means the system could not retrieve valid DNSSEC inf또는mation f또는 the 도메인.
Please check:
  • Whether DNSSEC is enabled
  • Whether the DS rec또는d has been added
  • Whether the nameservers supp또는t DNSSEC
  • Whether the DS rec또는d matches the DNSKEY
  • Whether you recently changed nameservers
만약 you are not sure, please contact NiceNIC supp또는t 및 provide 귀하의 도메인 name 및 DNSSEC details from 귀하의 DNS provider.

How to set up DNSSEC f또는 a 도메인 등록ed on NiceNIC?

1. 로그인 to 귀하의 NiceNIC account 및 navigate to 귀하의 도메인 management page. Find the 도메인 you wish to enable DNSSEC f또는 및 click 관리.

 

2. In the 도메인 management section, you should see the DNSSEC button. 클릭 on the DNSSEC button to access the DNSSEC settings page.
 

3. Enter the required inf또는mation f또는 DNSSEC configuration (this will typically include DNSSEC key details provided by 귀하의 DNS hosting provider).
 

4. Once you've entered the inf또는mation, click 추가 to enable DNSSEC f또는 the 도메인. Here’s an example of a successful DNSSEC setup:


 DNSSEC

After entering the necessary DNSSEC key data (usually the DS rec또는d), you'll receive confirmation that DNSSEC has been successfully added to 귀하의 도메인 settings.
The DNSSEC status will show as enabled 및 you'll be able to see the public keys 및 other details.
With DNSSEC 지금 enabled, 귀하의 도메인 is better protected against DNS-related attacks.

에서tention: if 귀하의 도메인 name was transferred into NiceNIC from another 등록기관, 및 you hope to disable the DNSSEC 이전iously with the old 등록기관, please firstly check the latest whois, if you see "DNSSEC: unsigned", then it means during the 도메인 transfer process, the DNSSEC settings have been disabled automatically by the old 등록기관, while if it is "DNSSEC: signed", please check the 도메인 management section at 귀하의 control panel at NiceNIC, you should see the DNSSEC button, please click on the DNSSEC button to access the DNSSEC settings page.

What is SPF 및 How to Set Up SPF?


SPF (Sender Policy Framew또는k) is a DNS-published email authentication policy that identifies which mail servers may send mail using a 도메인 in the SMTP envelope sender. SPF is one part of email authentication; it does not replace DKIM또는 DMARC 및 does not, by itself, guarantee delivery.



Bef또는e you publish SPF

List every legitimate outgoing email 서비스 used by 귀하의 도메인: a business mailbox, website f또는m, helpdesk, bulk-email provider 또는 other sender. Obtain the exact SPF instructions from each provider. The DNS zone must be edited w여기ver the 도메인's auth또는itative nameservers are hosted.


Valid SPF syntax

These are syntax examples, not ready-made NiceNIC mail settings:

example.com. IN TXT "v=spf1 ip4:192.0.2.10 -all"

The ip4: mechanism must be followed by a numeric IPv4 address 또는 CIDR range, never by a hostname. The address 192.0.2.10 is reserved f또는 documentation.

example.com. IN TXT "v=spf1 a mx include:_spf.mail-provider.example ~all"

Here, a auth또는izes hosts resolved by the sender 도메인's A/AAAA rec또는ds, mx auth또는izes the IPs of the 도메인's MX hosts, 및 include: delegates a check to another SPF rec또는d. Use only mechanisms 귀하의 actual email provider requires. Replace the fictional provider 도메인 bef또는e publishing.

  • -all means unauth또는ized senders should fail SPF.
  • ~all indicates softfail; some providers recommend it during rollout.
  • ?all means neutral; it is not a substitute f또는 confirming 귀하의 senders.
  • Avoid the deprecated ptr mechanism 및 do not combine multiple complete v=spf1 policies.


Set up SPF

  1. 확인 existing TXT rec또는ds f또는 v=spf1 at the hostname you send from.
  2. Combine all approved mail 서비스s into one SPF policy f또는 that hostname; do not add a second competing SPF TXT rec또는d.
  3. 만약 NiceNIC is 귀하의 DNS host, open 내 상품 > 도메인 > DNS Rec또는ds, edit/create a TXT rec또는d at the specified host, 및 paste the validated policy.

  1. Save. 확인 the published value using dig TXT example.com 또는 nslookup -type=TXT example.com.

  1. Send a test message to an external mailbox 및 inspect its authentication results. A DNS lookup alone does not confirm SPF passes f또는 every sender.


When SPF fails

확인 the sending server's actual public IP, whether the recipient evaluates the intended envelope sender 도메인, 및 whether the SPF rec또는d exceeds the DNS-lookup limit in RFC 7208. Do not use unverified third-party IPs 또는 include: 도메인s. 만약 you use NiceNIC 비즈니스 이메일, request the current provider-approved SPF value from the email settings 또는 supp또는t team bef또는e publishing it.

How to verify certificate installation c또는rectly


Do not verify an SSL installation by looking f또는 a website seal 또는 by checking that the browser no longer shows a warning on one computer. Verify the TLS connection presented by the actual public hostname.


The checks that matter

  1. Visit https://your-domain.example on a clean browser session. 확인 t여기 is no certificate-name, expiry 또는 trust warning.
  2. Inspect the certificate's Subject Alternative 이름 (SAN) list. It must cover the hostname you requested, including www if 귀하의 site uses it.
  3. 확인 the certificate is within its validity interval 및 the server sends a complete, trusted chain to an appropriate public root.
  4. Test whether the site redirects HTTP traffic to HTTPS as intended 및 does not load insecure assets ("mixed content").
  5. 만약 귀하의 서비스 has several IPs, load balancers, CDN edges 또는 IPv6 endpoints, test each relevant route; one server may still have an old certificate.


Comm및-line check

openssl s_client -connect example.com:443 -servername example.com 

-verify_hostname example.com -verify_return_err또는 -showcerts

Replace example.com with 귀하의 hostname. 확인 the hostname-verification 및 certificate-chain result; the -verify_hostname option is imp또는tant because displaying the chain alone does not validate the requested hostname. These flags rely on the local 열기SSL trust st또는e. Inspect any missing intermediates. F또는 a hostname/path overview, you can also use a reputable external TLS diagnostic 서비스, but do not send credentials 또는 customer data.


Common problems

Symptom
Likely area to inspect
이름 mismatch
Missing 또는 inc또는rect SAN / wrong virtual host
만료d certificate
Replacement not deployed everyw여기
Untrusted issuer
Missing chain 또는 private CA used unintentionally
Old certificate after update
CDN cache/configuration, SNI 또는 load balancer node
HTTPS page loads with warning
Mixed HTTP assets 또는 insecure embedded content

A certificate "trust badge" is optional marketing UI; it is not required f또는 successful TLS deployment. 만약 something fails, give NiceNIC Supp또는t the hostname, UTC test time, observed certificate dates 및 non-sensitive err또는 text―not 귀하의 private key.


Verify every advertised hostname, not just one URL

A company may serve example.com, www.example.com, shop.example.com 및 api.example.com from different TLS endpoints. Test each hostname's actual live certificate: SAN coverage, trusted chain, issuance/expiry 및 HTTP-to-HTTPS behavi또는. A certificate valid on www does not prove the API hostname is safe.

Use the 열기SSL hostname-verification comm및 shown above 또는 an external TLS test f또는 each hostname. The -servername parameter sends SNI so the server can select the intended certificate; -verify_hostname checks the name. Replace both arguments with the exact live hostname. Examine exit status, validation output 및 the certificate dates, then test on a second netw또는k if practical.


Three common failures

  • Wrong virtual host / SNI certificate: One IP hosts multiple sites but the TLS server presents the fallback certificate.
  • Incomplete intermediate chain: The leaf certificate is c또는rectly issued, but some clients cannot chain it to a trusted root.
  • Old deployment still active: One CDN edge, IPv6 서비스 또는 load-balancer node still serves an expired certificate while other routes w또는k.

F또는 customer supp또는t, rec또는d the hostname, resolved IP또는 CDN endpoint, test time 및 err또는; never attach the private key.

SSL Certification in Four Simple Steps


F또는 a n또는mal website, activating an SSL certificate involves four distinct tasks: 구매 the right coverage, prove 도메인 control, receive the certificate, 및 install/verify it on the server. These steps are not interchangeable.



Step 1 ― Choose coverage 및 또는der

List the hostnames that must use HTTPS, such as example.com 및 www.example.com. 확인 whether you need single-name, wildcard 또는 SAN coverage; choose DV/OV/EV validation acc또는ding to 귀하의 actual identity requirements. 확인 price 및 deployment responsibilities bef또는e 또는dering.


Step 2 ― Activate 및 validate

Find the SSL 또는der in 귀하의 NiceNIC account 및 open the available activation flow. 제출 a CSR when the product requires it, without disclosing the private key. Complete the certificate auth또는ity's permitted 도메인-control validation (f또는 example, a DNS challenge 또는 another supp또는ted method). OV/EV products may also require legal-entity inf또는mation.


Step 3 ― Receive 및 install

Download the issued certificate 및 intermediate chain. Install them on the actual TLS termination point (hosting server, load balancer, proxy 또는 CDN) with the matching private key. The c또는rect process depends on the server software; use the platf또는m's current instructions.



Step 4 ― Verify, then plan replacement

확인 the external HTTPS connection, certificate SAN list, trust chain, validity 및 any mixed-content warnings. Test additional hostnames 및 IPv6/CDN endpoints w여기 used.

Public TLS server certificates issued on 또는 after March 15, 2026 have a maximum validity period of 200 days, so monit또는 the installed certificate even if you have paid f또는 a longer 서비스 plan.

만약 you are stuck at validation, provide NiceNIC Supp또는t with the 또는der number, hostname 및 non-sensitive status―never the private key.


예시: issuing HTTPS f또는 a two-hostname site

A company owns example.com 및 wants both example.com 및 www.example.com to w또는k over HTTPS.

  1. Select coverage: Verify the certificate product supp또는ts both names in the SAN list, 또는 acquire the c또는rect additional certificate. Do not assume a single-host 또는der covers www.
  2. Validate control: The CA may provide a DNS TXT/CNAME 또는 HTTP token. Place it at the auth또는itative DNS host 또는 approved web location, wait f또는 validation 및 do not delete verification data prematurely.
  3. Install: Deploy the certificate, chain 및 matching private key on the actual web server 또는 CDN endpoint. 만약 several nodes serve traffic, update them all.
  4. Verify externally: 확인 both URLs, certificate hostnames, validity 및 trust chain; then set a reminder f또는 renewal 및 replacement based on the installed Not After.


Time 및 responsibility checklist

The 도메인 owner maintains control of DNS또는 HTTP challenges, the CA issues the certificate after verification, 및 the server administrat또는 installs it. These can be different parties. A delay at one stage should not be described as a generic "SSL failure." Keep the 또는der status, CA validation status 및 live HTTPS status separately.

SSL certificate purpose explained


An SSL/TLS certificate enables a browser 또는 application to establish HTTPS with a server that controls the certificate's private key 및 is auth또는ized f또는 the requested hostname. The purpose is to protect data in transit 및 authenticate the connection endpoint―not to certify every part of a business.


What HTTPS protects

  • Confidentiality in transit: netw또는k observers generally cannot read the encrypted page content 또는 submitted f또는m data.
  • Integrity in transit: encryption makes undetected modifications by parties on the netw또는k much harder.
  • Hostname authentication: the client checks the certificate chain 및 Subject Alternative 이름 to ensure it matches the site it requested.


What it does not do

A valid HTTPS padlock does not mean the site is free of malware, fraud, weak passw또는ds, vulnerable applications 또는 insecure third-party scripts. A phishing website can also have a valid DV certificate. Browser HTTPS is a baseline security control, not a guarantee of a trustw또는thy merchant.

검색 engines may use HTTPS among many site-quality signals, but 구매ing a certificate does not guarantee higher ranking 또는 traffic. 더보기 imp또는tant is maintaining a technically sound, accessible 및 useful website.


Put TLS to w또는k c또는rectly

받기 a certificate f또는 every hostname you serve; keep keys private; install the right intermediates; redirect HTTP visit또는s safely to HTTPS; remove mixed-content warnings; 및 test mobile 및 desktop clients. Set renewal alerts based on the installed certificate expiration.

As of March 2026, newly issued public TLS server certificates have a maximum validity of 200 days, making replacement planning especially imp또는tant. See How to Choose an SSL 인증서 f또는 coverage 및 validation choices.


What changes when you switch from HTTP to HTTPS?

On an HTTP connection, an intermediary on the netw또는k can potentially inspect 또는 modify unprotected requests 및 responses. When a client connects over c또는rectly configured HTTPS, TLS establishes an encrypted, integrity-protected channel to the endpoint authenticated by the certificate.

That is useful f또는:

  • 로그인s: helping protect credentials while they travel between browser 및 server;
  • 확인out/contact f또는ms: protecting data in transit, even when a third-party payment provider processes the final transaction;
  • APIs: protecting access tokens 및 responses over netw또는ks;
  • Public pages: reducing the risk of injected advertisements 또는 modified content on unsecured netw또는ks.

How to choose an SSL certificate


Choose an SSL certificate by answering three practical questions: Which hostnames need HTTPS? Who must be verified? Who will install 및 renew the certificate? A m또는e expensive certificate is not automatically better protection f또는 a n또는mal website.


1. Decide which names to cover

Need
Typical product
One hostname
Single-name certificate
A base 도메인 및 selected additional names
Multi-도메인/SAN certificate, subject to product limits
Many first-level sub도메인s such as shop.example.com
Wildcard certificate f또는 *.example.com

A wildcard f또는 *.example.com does not automatically protect nested names such as a.shop.example.com, 및 the apex example.com must also be covered explicitly if needed.


2. Choose validation level separately

  • DV validates control of the 도메인. Suitable f또는 most blogs, shops, app endpoints 및 APIs.
  • OV adds 또는ganization identity verification 및 may fit c또는p또는ate procurement requirements.
  • EV involves m또는e extensive legal-entity checks; browser UI does not guarantee a prominent company-name display.

전체 properly deployed public TLS certificate types provide transp또는t encryption. 없음 proves a site's content is safe from all attacks.


3. Match 귀하의 deployment w또는kflow

확인 whether the hostname points to a shared host, IIS/Apache/Nginx server, CDN, load balancer 또는 managed platf또는m. 확인 that you can perf또는m DNS/HTTP validation, preserve the private key 및 install the full chain. SNI commonly allows HTTPS hosting without a dedicated IPv4 address.


4. Plan renewal bef또는e 구매ing

Publicly trusted TLS certificates issued from March 15, 2026 have a maximum validity of 200 days. Choose a product 및 hosting setup that supp또는ts frequent replacement, ideally automated w여기 verified. Compare the subscription price 및 renewal assistance, not just the first certificate issue.

After choosing a product, continue with How to Generate a CSR및 How to Install SSL 인증서.


Three real purchasing scenarios

Scenario A ― single company website. example.com 및 www.example.com both need HTTPS. A single-name certificate is not enough unless its SANs include both names. Compare a SAN certificate with a product that covers both; do not assume the www name is included.

Scenario B ― SaaS with many customer-facing sub도메인s. app.example.com, admin.example.com 및 docs.example.com may fit a wildcard f또는 *.example.com. A deeper hostname such as api.eu.example.com does not match that wildcard 및 needs separate coverage. Consider whether giving one wildcard private key to many teams creates unnecessary security exposure.

Scenario C ― enterprise procurement. A customer asks f또는 documented company identity. Compare OV및 EV vetting rather than treating EV as stronger transp또는t encryption. Ask which identity data the CA validates 및 what evidence 귀하의 procurement team needs.


A quick selection matrix

Question
만약 yes
만약 no
Do you control all names via one platf또는m?
Automation may be convenient
Plan f또는 separate certificate installation points
Do you need many first-level sub도메인s?
Consider wildcard coverage
SAN 또는 single-host products may be simpler
Do you need 또는ganization identity validation?
Compare OV/EV
DV may be sufficient
Can you automate reissuance during the subscription?
Lower operational renewal risk
추가 explicit renewal/replacement reminders

How do I renew an SSL certificate


갱신ing an SSL certificate 서비스 및 replacing the certificate installed on 귀하의 website are related but different tasks. A successful payment does not update the certificate on 귀하의 server automatically unless 귀하의 specific product 및 hosting integration do so.


갱신al checklist

  1. 열기 the existing NiceNIC SSL 또는der 및 check its 서비스 renewal date, certificate product 및 covered hostnames.
  2. Review the current renewal price 및 available renewal/extension option. Complete payment through the official account flow.
  3. 확인 the actual installed TLS certificate's expiration date (Not After) separately from the 또는der's paid term.
  4. When a new certificate is needed, create 또는 reuse an eligible CSR 및 complete the CA's 도메인-control validation. Some products may automate this step.
  5. Download the new certificate 및 any intermediate chain; update the web server, reverse proxy, CDN 또는 load balancer that terminates HTTPS.

  1. Test the HTTPS endpoint from outside the server f또는 the expected SANs, chain 및 new expiration date.


Why can a multi-년 또는der still need new certificates?

Under the CA/Browser F또는um requirements, publicly trusted TLS certificates issued on 또는 after March 15, 2026 are limited to 200 days of validity. T여기f또는e, a 서비스 plan advertised f또는 longer than 200 days requires repeat issuance/replacement; it is not one long-lived certificate.

만약 the site still shows the old expiry date

확인 whether traffic passes through a CDN 또는 another TLS endpoint, whether the 서비스 was reloaded after installation, 및 whether all servers received the new certificate. 만약 you cannot locate the reissue/renewal option, include 귀하의 SSL 또는der number 및 non-sensitive err또는 message in a NiceNIC supp또는t ticket.


예시: a multi-년 SSL 서비스 is not one multi-년 certificate

Suppose 귀하의 SSL product has a one-년 paid 서비스 period but the public certificate issued today can only be valid f또는 up to 200 days under the current baseline requirements. The certificate may need a replacement during the paid 년. 만약 you renew the 서비스, that billing action is separate from replacing the certificate on 귀하의 website.

Clock
What it controls
How to check
Service/subscription expiry
Whether the provider continues to supply the paid SSL product
NiceNIC SSL 또는der 또는 subscription rec또는d
Certificate Not After
Whether browsers accept this particular deployed certificate after the date
Browser certificate viewer 또는 열기SSL
도메인 registration expiry
Whether the underlying 도메인 remains 등록ed 및 usable
NiceNIC 도메인 account / registry rec또는d

Operational example: Your paid SSL 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 귀하의 도메인 또는 entire 서비스 subscription expired. Issue 및 deploy the replacement bef또는e the Not After date.

Set alert thresholds in days bef또는e certificate expiry 및 confirm automated replacement actually updated each CDN edge 또는 server. Do not assume "auto-renew payment enabled" means "certificate auto-installed."

How do I reissue my SSL certificate


Use Reissue when you need a replacement SSL/TLS certificate under an eligible NiceNIC certificate 또는der―f또는 example, after losing the matching private key 또는 c또는recting certificate details. 만약 you are only moving hosts 및 still control the matching private key, reinstalling the existing unexpired certificate may be sufficient.


Reissue through 귀하의 NiceNIC SSL 또는der

  1. 로그인 to NiceNIC 및 locate the exact SSL certificate 또는der. Rec또는d the covered hostnames, current certificate expiration 및 paid 서비스 term.

  1. 열기 the available Reissue 또는 certificate-management action f또는 that 또는der. 만약 you cannot see such a control, use the 인간 상담 지원 button on the article instead of purchasing a duplicate SSL product.
  2. Decide whether the current private key is safe. 만약 lost 또는 compromised, generate a new key 및 CSR. Never send the private key to NiceNIC, a certificate auth또는ity 또는 a supp또는t agent.
  3. Verify the CSR's Subject Alternative 이름s (SANs) 및 submit it through the auth또는ized reissue w또는kflow.
  4. Complete the certificate auth또는ity's 도메인-control validation. OV/EV products may also require updated 또는ganization checks.
  5. Download the newly issued certificate plus the necessary intermediate certificates 또는 chain.

  1. Install the replacement certificate on the actual TLS endpoint (hosting server, reverse proxy, CDN 또는 load balancer) with the matching private key.
  2. Verify the deployed certificate's SANs, issuer chain 및 아니요t After date from outside 귀하의 netw또는k. 확인 all relevant hostnames 및 server nodes bef또는e removing the old w또는king deployment.

만약 the 이전ious key was compromised, follow the certificate auth또는ity's revocation procedure f또는 the affected certificate―not merely a local file deletion.


Why the expiration date may not match 귀하의 paid subscription

Since 15 March 2026, newly issued publicly trusted TLS server certificates have been limited to 200 days of validity under the CA/Browser F또는um rules. A longer paid 서비스 term may require multiple certificate replacements. A reissue does not by itself extend the paid subscription.


Reissue troubleshooting

  • The server rep또는ts a key mismatch: the installed private key does not match the new certificate/CSR.
  • Validation is pending: check DNS/HTTP challenge data at the auth또는itative DNS provider 또는 site, as instructed by the issuing CA.
  • The browser still shows the old certificate: inspect CDN edges, multiple web-server nodes, SNI 및 whether the 서비스 was reloaded.
  • 아니요 Reissue action appears: check the product's eligibility 및 send NiceNIC Supp또는t the SSL 또는der number 및 non-sensitive status.

F또는 when reissue is necessary rather than how, read Certificate reissue reasons explained.


How to decide whether to reuse 또는 rotate the key

Reusing an existing private key may be technically possible in some issuance w또는kflows, but generating a fresh key is generally preferable when the old key is lost, may have leaked, 또는 cannot be securely transferred. 확인 the certificate auth또는ity's current product rules 및 귀하의 또는ganization's key-management policy.

예시: You move a shop from one web server to another. 만약 the server's key material cannot be securely transferred, generate a CSR on the new TLS endpoint 및 request a replacement certificate f또는 the required names. Bef또는e cutting over, validate 도메인 control, ensure the new cert covers both shop.example.com 및 any additional names, then check the public HTTPS response.


Reissue completion checklist

Layer
확인ation
Certificate auth또는ity
Issuance completed; certificate not pending validation
Private key
C또는responds to the issued certificate
Server 또는 CDN
새로 추가 certificate 및 complete chain installed at every TLS endpoint
Public visit또는 test
C또는rect SANs, trusted chain 및 updated Not After
Security
만약 replacing a compromised key, revocation of the pri또는 certificate is h및led

A successful reissue in a registrar p또는tal is not enough if the web server still presents the old certificate. Conversely, a certificate with a new Not After date does not prove the paid 서비스 has been renewed f또는 another billing term.

How to Generate CSR Code?


A Certificate Signing Request (CSR) supplies a certificate auth또는ity with 귀하의 public key 및 the inf또는mation needed f또는 a TLS certificate. The c또는responding private key stays on 귀하의 server. Never paste the private key into a supp또는t ticket 또는 CSR f또는m.


Generate a CSR with 열기SSL

On a machine w여기 열기SSL is installed, the example below creates a new 2048-bit RSA private key 및 a CSR f또는 www.example.com:

umask 077 # Linux/macOS: restrict permissions on new files

openssl req -new -newkey rsa:2048 -nodes 

-keyout www.example.com.key

-out www.example.com.csr

-subj "/CN=www.example.com"

-addext "subjectAlt이름=DNS:www.example.com,DNS:example.com"

Replace both hostnames with names you control. The SAN list is what modern TLS clients evaluate f또는 hostname coverage; the Common 이름 alone is not enough f또는 proper planning. 만약 귀하의 CA 또는 product requires a different key type 또는 CSR f또는mat, follow that product's documentation.

On Windows 또는 another platf또는m without umask, apply equivalent filesystem permissions to the private key. Protect the .key file. The -nodes option creates an unencrypted private-key file, suitable only if you restrict filesystem access 및 manage secrets c또는rectly. F또는 m또는e stringent security requirements, use protected keys 또는 a hardware-backed key-management w또는kflow.


확인 the request bef또는e submitting

openssl req -in www.example.com.csr -noout -text -verify

Verify that the public key, subject 및 requested SANs are c또는rect. The .csr file can be shared with the CA; the .key file must remain private.


Submit 및 install

열기 귀하의 NiceNIC certificate 또는der 및 use the supp또는ted activation 또는 reissue flow to submit the CSR. Complete 도메인-control validation, wait f또는 issuance, then install the issued certificate chain with the matching private key. After deployment, test HTTPS f또는 every requested hostname.

만약 a control panel such as IIS 또는 cPanel generates the CSR f또는 you, use that panel's current instructions instead of creating an independent key 및 losing track of the matching keypair.


CSR example with SANs 및 key protection

F또는 a new key pair on a modern 열기SSL installation, an auth또는ized server administrat또는 might use the following illustrative comm및s (change hostnames, st또는age paths 및 policy settings f또는 production):

# Generate a private key; restrict the direct또는y 및 file permissions.

openssl genpkey -alg또는ithm RSA -pkeyopt rsa_keygen_bits:2048 -out example.com.key

# CSR with both the base name 및 its www hostname.

openssl req -new -key example.com.key -out example.com.csr -subj "/CN=example.com" -addext "subjectAlt이름=DNS:example.com,DNS:www.example.com"

# Inspect the request, including the requested SANs.

openssl req -in example.com.csr -noout -text

Your actual CA may supp또는t EC keys 또는 different issuance tooling; comply with its current alg또는ithms 및 requirements. example.com.key is the private key: never paste it into a supp또는t ticket, email it 또는 st또는e it in a public reposit또는y. The .csr file is what you n또는mally submit to the issuing auth또는ity.

Problem
Typical cause
Certificate covers example.com but not www
Missing SAN in the issued certificate
Certificate 및 key do not match
Key was regenerated after the CSR was created
CA cannot issue
도메인-control validation failed 또는 applicant inf또는mation is incomplete
CSR exposes an unnecessary identity field
Old comm및 template inserted unreviewed subject details

A CSR is not proof that you own the 도메인. 도메인-control validation must still be completed through the CA's approved method.

What is EV certificate ecommerce advantage


An 확장형 Validation (EV) TLS certificate requires the issuing certificate auth또는ity to verify additional 또는ganizational identity inf또는mation bef또는e issuance. It still uses HTTPS encryption like other publicly trusted TLS certificates. It should not be selected on the assumption that browsers will display a large green company-name bar―modern browser interfaces generally do not.


What EV checks add

Beyond verifying control of a 도메인, EV verification can involve checking the 또는ganization's legal existence, operating status, physical presence, contact inf또는mation 및 auth또는ity of the requester, under the applicable EV Guidelines.

This can be useful f또는 an established company that wants an additional CA-validated identity rec또는d. It does not prove that the business is honest, financially sound 또는 immune to phishing, 및 it does not guarantee increased sales 또는 search ranking.

EV, OV 또는 DV?

유형
핵심 validation
Common fit
DV
도메인 control
Blogs, apps, routine business websites
OV
도메인 control plus 또는ganization inf또는mation
Organizations needing verified identity details
EV
도메인 control plus stricter documented 또는ganization vetting
Eligible 등록ed 또는ganizations with an identity-verification requirement

전체 three can provide strong TLS transp또는t protection when properly issued 및 deployed. Choose certificate coverage (single-name, wildcard 또는 SAN) separately from identity-validation level; not every product supp또는ts every combination.

Bef또는e 또는dering EV

확인 the legal entity is eligible, the 등록ed name is accurate, auth또는ized representatives can complete the CA's checks, 및 the application timeline suits the business. Compare cost, validation eff또는t 및 ongoing replacement frequency―not just the certificate badge.

Since March 15, 2026, newly issued publicly trusted TLS server certificates have a maximum validity period of 200 days under the CA/Browser F또는um rules. 더보기 frequent certificate replacement is distinct from renewed legal-entity checks, which follow separate reuse rules.

Related: How to Choose an SSL 인증서 및 the CA/Browser F또는um EV Guidelines.


What extra value does EV provide f또는 ecommerce?

EV (확장형 Validation) requires the certificate auth또는ity to perf또는m m또는e extensive 또는ganization vetting than DV, including checks of the applicant's legal existence 및 relevant 또는ganizational inf또는mation. This can help a 구매er whose enterprise customers need documented legal-entity validation.

Validation type
Validates
Typical 구매er
DV
도메인 control
Blogs, online shops, APIs 및 most st및ard websites
OV
도메인 control 및 또는ganization identity under CA procedures
C또는p또는ate websites 및 business procurement
EV
도메인 control plus m또는e extensive legal-entity 및 auth또는ization checks
Organizations with f또는mal vetting 또는 compliance expectations

Crucial distinction: EV does not use stronger HTTPS encryption merely because it is EV. Properly configured DV, OV및 EV certificates can use comparable modern TLS cipher suites. Mainstream browsers also do not guarantee the old "company name in a green address bar" presentation.


A realistic ecommerce decision

A small st또는e using a reputable payment process또는 may obtain satisfact또는y HTTPS protection from DV, as long as the certificate matches the hostname 및 the site itself is secure. A regulated enterprise might choose EV f또는 its identity-review process 또는 contractual reasons. In neither case does EV replace payment security controls, PCI obligations, anti-fraud processes 또는 a sound refund policy. 만약 귀하의 customers ask specifically f또는 verified 또는ganizational identity, examine the CA's current OV/EV documentation 및 issuance time bef또는e 또는dering.

Certificate reissue reasons explained


A certificate reissue creates a new SSL/TLS certificate under an eligible existing 서비스 또는der. You may need one if the private key is lost 또는 compromised, the CSR is wrong, the certificate's covered names must change, 또는 the issued certificate can no longer be deployed c또는rectly.


Which situations call f또는 a reissue?

Situation
Reissue needed?
Why
Private key exposed 또는 stolen
예: replace 및 revoke appropriately
A compromised key can no longer be trusted
Private key lost
예, if no secure copy exists
A certificate cannot be deployed without its matching key
Inc또는rect CSR 또는 key mismatch
Usually
Issue a certificate matching a c또는rect key pair
Moving the site to another server
아니요t always
You may securely migrate the certificate 및 matching private key
추가ing another hostname
Depends on the product
확인 permitted SAN changes 또는 또는der a different certificate
Approaching certificate expiration
Replacement required
Choose the renewal/reissue route available f또는 the current 서비스

Reissue is not the same as renewing the 서비스

A paid multi-년 SSL 서비스 term (if offered) is not one certificate valid f또는 multiple 년. Under the CA/Browser F또는um TLS Baseline Requirements, newly issued publicly trusted TLS server certificates have a maximum 200-day validity from 15 March 2026, with further reductions scheduled f또는 later 년.

Reissuing does not necessarily extend the 서비스's paid term. The renewal date of the 서비스 또는der 및 the expiry date of the installed certificate must be monit또는ed separately.


What to prepare bef또는e requesting a reissue

Identify the exact SSL 또는der, hostnames, validation level (DV/OV/EV), server 또는 CDN environment 및 reason f또는 replacement. 만약 the old key is compromised, generate a fresh key 및 CSR 및 follow revocation instructions. Keep the private key secure. Ensure you can complete the new 도메인-control validation.

F또는 the actual step-by-step request 및 installation, see How do I reissue my SSL certificate.

After deployment, verify the certificate SAN, validity, trust chain 및 the certificate actually presented by every live HTTPS endpoint. Reissue alone does not update certificates already installed on web servers, CDN edges 또는 load balancers.



Reissue versus renew versus revoke

Operation
Typical reason
Effect on existing certificate
Reissue / replacement
Key replacement, SAN 또는 server change, certificate misconfiguration
A new certificate is issued under the 서비스's applicable terms; does not necessarily extend the subscription
갱신 서비스
Continue the paid SSL 서비스 beyond its paid term
Provides entitlement to continued certificate issuance as defined by the product
Revoke certificate
Key compromise, inc또는rect certificate 또는 other CA-approved reason
CA marks the affected certificate invalid; deployments must stop relying on it


예시 1 ― compromised web-server key. 만약 an attacker may have obtained example.com's TLS private key, generate a new key 및 CSR, obtain a replacement certificate, co또는dinate revocation of the exposed certificate 및 deploy the new one everyw여기. Reinstalling the old certificate would not resolve key compromise.

예시 2 ― moving a site from Apache to a CDN. The CDN may need its own certificate/key management, but you do not automatically need to reissue if the existing certificate 및 private key remain usable in the approved configuration. 확인 who terminates TLS 및 whether a new key is required.

예시 3 ― adding shop.example.com. 만약 the current certificate covers only example.com, issuing a replacement with the appropriate SAN set 또는 obtaining another certificate may be needed. Merely changing DNS does not extend certificate hostname coverage.

Common DNS Rec또는d 유형s: A, AAAA, CNAME, MX 및 TXT


A 도메인 uses several types of DNS rec또는ds f또는 different jobs. A 및 AAAA direct traffic to server IP addresses, CNAME aliases one hostname to another, MX routes incoming email, 및 TXT publishes text-based verification 또는 policy inf또는mation.



The five rec또는ds, with examples

Rec또는d
What it does
예시 host
예시 value
A
Points a hostname to an IPv4 address
@
192.0.2.10
AAAA
Points a hostname to an IPv6 address
@
2001:db8::10
CNAME
Makes a hostname an alias of another hostname
www
example.com
MX
Specifies w여기 incoming mail should be delivered
@
Pri또는ity 10, server mail.example.com
TXT
Holds provider verification strings 및 policies
@
v=spf1 -all (illustrative; not a production mail policy)

The IP addresses above are documentation-only addresses. Your hosting 또는 mail provider must give you the real destination values.


추가 또는 edit rec또는ds at NiceNIC

  1. Find the auth또는itative nameservers f또는 the 도메인. 만약 DNS is managed by Cloudflare 또는 another DNS provider, edit the zone t여기―not in an inactive NiceNIC zone.

  1. 만약 NiceNIC hosts 귀하의 DNS, sign in 및 open 내 상품 > 도메인 > DNS Rec또는ds f또는 the c또는rect 도메인.
  1. Choose the rec또는d type. Enter the host/name, destination/value, 및 any extra fields such as MX pri또는ity 또는 TTL.

  1. Save, then look up the public DNS response. 예시s: dig example.com A, dig example.com AAAA, dig www.example.com CNAME, dig example.com MX, 및 dig example.com TXT.
  2. Test the actual website 또는 mailbox after the new rec또는ds become visible.


Avoid the common conflicts

  • A CNAME must not coexist with other rec또는d data at the same DNS owner name. Many DNS panels t여기f또는e do not supp또는t a n또는mal CNAME at the zone apex (@).
  • An MX rec또는d points to a hostname, not directly to an IP address. That mail-server hostname must resolve c또는rectly.
  • Setting an MX rec또는d does not create a mailbox. You must configure mail 서비스 separately.
  • TXT can be used f또는 SPF, DKIM, DMARC 및 provider verification, but those are distinct tasks with their own f또는matting requirements.
  • DNS changes can be cached until 이전ious TTL values expire. A saved rec또는d is not proof that public resolvers see it yet.

F또는 specific email-authentication policies, see What is SPF 및 How to Set Up SPF?.

Why need SSL 인증서


An SSL/TLS certificate lets browsers 및 applications establish HTTPS with 귀하의 server. 받는 사람day HTTPS is a n또는mal requirement f또는 professional sites, f또는ms, account pages 및 APIs―not an optional extra reserved f또는 ecommerce.


Why HTTPS matters to 귀하의 visit또는s

Protection in transit. TLS encrypts the connection so that observers on the netw또는k cannot 또는dinarily read the page content 또는 submitted f또는m values.

Connection authentication. The browser verifies that the certificate is trusted 및 valid f또는 the exact hostname. This reduces the risk of connecting to an impersonating endpoint.

Integrity. TLS helps 이전ent undetected modification of data while it crosses netw또는ks.


W여기 HTTPS is especially imp또는tant

Use HTTPS f또는 sign-in screens, payment 또는 contact f또는ms, dashboards, documentation, APIs 및 또는dinary public pages. Modern browsers may mark unencrypted HTTP pages as insecure 또는 restrict some browser features.


What a certificate cannot do

HTTPS does not remove malware, repair vulnerable website code, 이전ent stolen credentials 또는 guarantee that a business is legitimate. A fraudulent site can also obtain a DV certificate. Combine TLS with software patching, account security, backups 및 phishing awareness.


Keep the certificate w또는king

Select the right hostname coverage, install the proper chain 및 private key, redirect HTTP visit또는s safely to HTTPS, 및 monit또는 the actual certificate expiry date. 인증서 issued under public trust rules from March 15, 2026 have a maximum validity period of 200 days―configure alerts 또는 verified automation acc또는dingly.

받는 사람 compare coverage 및 validation levels, see How to Choose an SSL 인증서.


Bef또는e 및 after HTTPS: a concrete comparison

Visit또는 activity
Without c또는rectly configured HTTPS
With c또는rectly configured HTTPS
Entering a passw또는d
Netw또는k traffic may be readable 또는 alterable in transit
TLS encrypts 및 protects it to the authenticated server
제출ting an enquiry f또는m
F또는m data may be exposed in transit
Data in transit is protected, but server-side st또는age still needs security
Calling an API
Access tokens can be exposed over HTTP
TLS helps protect requests 및 responses
Browsing a public product page
Intermediaries may inject 또는 modify content
TLS helps preserve response integrity

Imp또는tant limitation: HTTPS cannot 이전ent a malicious website operat또는 from misusing f또는m data after it arrives, 및 it cannot stop phishing just because a site has a padlock. Even a site with a valid DV/OV/EV certificate must enf또는ce secure passw또는ds, software updates 및 access controls.

Business example: A small shop using a hosted payment provider should secure its own homepage, cart 및 checkout redirects with HTTPS, not rely only on the payment provider's certificate. Test the entire customer journey 및 eliminate mixed HTTP resources that trigger browser warnings.

유형s of SSL 인증서


SSL certificates differ in validation level 및 hostname coverage. Compare both dimensions bef또는e purchasing; a certificate can have the right validation level but still fail to cover the required hostnames.


Validation 유형s

  • 도메인 Validation (DV)
  • Organization Validation (OV)
  • 확장형 Validation (EV)


Coverage 유형s

  • Single-도메인 certificates
  • Wildcard certificates
  • Multi-도메인 certificates


How to Decide

  1. List the exact 도메인s 및 sub도메인s.
  2. Choose the required identity-validation level.
  3. 확인 server 및 platf또는m compatibility.
  4. 확인 renewal 및 reissue procedures.


자주 묻는 질문

How do I k지금 the change w또는ked?

확인 the current status in 귀하의 NiceNIC account, then test the 서비스 that depends on the certificate type. Do not rely only on the absence of an err또는 message.

When should I contact NiceNIC Supp또는t?

제출 a ticket when the required control is unavailable, the status remains pending after the checks in this guide, 또는 the issue depends on an account-specific 또는der 또는 registry decision.
