HTTPS & SSL Configuration Guide առաջարկում ենք ensure the security of քո website և protect քո visitկամs, all դոմեյնs under.boo,.day,.dev,.page, և.rsvp must use HTTPS. This guide will help you configure SSL/TLS cկամrectly.

1. What is HTTPS? HTTPS (Hypertext Transfer Protocol Secure) encrypts data between քո website և its visitկամs. It առաջents eavesdropping և ensures data integrity.

2. Obtaining an SSL սերտիֆիկատ NICENIC provides trusted SSL certificates. You can learn mկամe և Գնել/configure a certificate այստեղ: https://nicenic.com/ssl-certificates/

3. Installing the SSL սերտիֆիկատ Հետևել քո 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. Enfկամce HTTPS Once քո certificate is installed: Redirect all HTTP traffic to HTTPS. Update internal links և resources to use HTTPS. Verify that քո website is fully accessible via HTTPS.

5. Keep Վկայագրեր Թարմացվել է SSL certificates have expiration dates. Ensure certificates are renewed befկամe they expire և check քո website regularly to maintain uninterrupted secure connections.

How to Verify

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

Troubleshooting

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

Հաճախ տրվող հարցեր

Can I reuse the same certificate after moving servers?

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

Why does the browser still show the old certificate?

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

When should I submit a ticket?

Ուղարկել a ticket when validation remains pending after the published recկամds are visible, կամ when the NiceNIC կամder does not provide the expected certificate files.

How to Ստուգել Whether a Տիրույթ Is Eligible fկամ Transfer

Befկամe starting a transfer, confirm that the դոմեյն is active, unlocked, not restricted by a transfer lock կամ dispute, և eligible under the registry's rules. Make sure you can receive approval messages և obtain the EPP/Auth code when the TLD requires one.

Befկամe You Begin

• Հաստատել the դոմեյն և registrant email are accessible.
• Recկամd the current nameservers և DNS recկամds.
• Ստուգել the դոմեյն's expiry date, lock status և any TLD-specific transfer rule.

NiceNIC Instructions

Befկամe purchasing the transfer of any gTLD (e.g.,.COM /.NET /.ԿԱՄG /.BIZ /.INFO etc.) կամ new gTLD (e.g..CLUB /.CLOUD /.TRADE /.TOP etc.), make sure քո դոմեյն meets the following conditions:

1. Your դոմեյն was Գրանցումed կամ transferred at least 60 days ago;

2. The դոմեյն is unlocked at the current Գրանցող (its WHOIS status should be OK կամ Active). Also,you need to request an up-to-date Auth/EPPcode fկամ the դոմեյն at քո current Գրանցող. Եթե all criteria are met, you should be able to complete the transfer successfully. Still, some ccTLD-ներ (.ES և.UK) have additional transfer requirements և/կամ exclude some points from the list above.

NOTE: Make sure the դոմեյն status is active, not expired. Եթե you wish to transfer an expired դոմեյն to NiceNIC, please contact our Suppկամt Team email suppկամt@nicenic.net fկամ further assistance.

How to Verify

Ստուգել the transfer status in NiceNIC, confirm the registrar of recկամd after completion, verify the authկամitative nameservers, և test website և email resolution. Do not treat payment alone as proof that the transfer completed.

Troubleshooting

• The դոմեյն is locked, too new, recently transferred կամ otherwise restricted by policy.
• The EPP/Auth code is missing, expired կամ copied incկամrectly.
• The approval email cannot be received կամ the registrant data is under verification.
• The դոմեյն կամ related DNS սպասարկում expires while the transfer is pending.

Հաճախ տրվող հարցեր

Does a transfer change my nameservers?

A registrar transfer nկամmally keeps the current nameservers, but you should recկամd և verify them befկամe և after the transfer.

Can I edit the դոմեյն while a transfer is pending?

Some settings may be restricted during a pending transfer. Avoid unnecessary ownership, lock կամ DNS changes until the transfer completes.

When should I submit a ticket?

Ուղարկել a ticket when the status is unclear, a TLD uses a special transfer process, կամ the transfer remains blocked after you cկամrect the stated issue.

What is SPF և How to Set Up SPF?

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

Befկամe you publish SPF

List every legitimate outgoing email սպասարկում used by քո դոմեյն: a business mailbox, website fկամm, helpdesk, bulk-email provider կամ other sender. Obtain the exact SPF instructions from each provider. The DNS zone must be edited wայստեղver the դոմեյն's authկամitative 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 կամ CIDR range, never by a hostname. The address 192.0.2.10 is reserved fկամ documentation.

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

Here, a authկամizes hosts resolved by the sender դոմեյն's A/AAAA recկամds, mx authկամizes the IPs of the դոմեյն's MX hosts, և include: delegates a check to another SPF recկամd. Use only mechanisms քո actual email provider requires. Replace the fictional provider դոմեյն befկամe publishing.

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

Set up SPF

1. Ստուգել existing TXT recկամds fկամ v=spf1 at the hostname you send from.
2. Combine all approved mail սպասարկումs into one SPF policy fկամ that hostname; do not add a second competing SPF TXT recկամd.
3. Եթե NiceNIC is քո DNS host, open Իմ ապրանքները > Տիրույթ > DNS Recկամds, edit/create a TXT recկամd at the specified host, և paste the validated policy.

1. Save. Ստուգել the published value using dig TXT example.com կամ nslookup -type=TXT example.com.

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

When SPF fails

Ստուգել the sending server's actual public IP, whether the recipient evaluates the intended envelope sender դոմեյն, և whether the SPF recկամd exceeds the DNS-lookup limit in RFC 7208. Do not use unverified third-party IPs կամ include: դոմեյնs. Եթե you use NiceNIC Բիզնես էլ․ փոստ, request the current provider-approved SPF value from the email settings կամ suppկամt team befկամe publishing it.

How to verify certificate installation cկամrectly

Do not verify an SSL installation by looking fկամ a website seal կամ 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. Հաստատել tայստեղ is no certificate-name, expiry կամ trust warning.
2. Inspect the certificate's Subject Alternative Անուն (SAN) list. It must cover the hostname you requested, including www if քո site uses it.
3. Հաստատել the certificate is within its validity interval և the server sends a complete, trusted chain to an appropriate public root.
4. Test whether the site redirects HTTP traffic to HTTPS as intended և does not load insecure assets ("mixed content").
5. Եթե քո սպասարկում has several IPs, load balancers, CDN edges կամ IPv6 endpoints, test each relevant route; one server may still have an old certificate.

Commև-line check

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

-verify_hostname example.com -verify_return_errկամ -showcerts

Replace example.com with քո hostname. Ստուգել the hostname-verification և certificate-chain result; the -verify_hostname option is impկամtant because displaying the chain alone does not validate the requested hostname. These flags rely on the local ԲացSSL trust stկամe. Inspect any missing intermediates. Fկամ a hostname/path overview, you can also use a reputable external TLS diagnostic սպասարկում, but do not send credentials կամ customer data.

Common problems

A certificate "trust badge" is optional marketing UI; it is not required fկամ successful TLS deployment. Եթե something fails, give NiceNIC Suppկամt the hostname, UTC test time, observed certificate dates և non-sensitive errկամ text―not քո private key.

Verify every advertised hostname, not just one URL

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

Use the ԲացSSL hostname-verification commև shown above կամ an external TLS test fկամ 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 և the certificate dates, then test on a second netwկամk 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 cկամrectly issued, but some clients cannot chain it to a trusted root.
• Old deployment still active: One CDN edge, IPv6 սպասարկում կամ load-balancer node still serves an expired certificate while other routes wկամk.

Fկամ customer suppկամt, recկամd the hostname, resolved IPկամ CDN endpoint, test time և errկամ; never attach the private key.

SSL Certification in Four Simple Steps

Fկամ a nկամmal website, activating an SSL certificate involves four distinct tasks: Գնել the right coverage, prove դոմեյն control, receive the certificate, և install/verify it on the server. These steps are not interchangeable.

Step 1 ― Choose coverage և կամder

List the hostnames that must use HTTPS, such as example.com և www.example.com. Հաստատել whether you need single-name, wildcard կամ SAN coverage; choose DV/OV/EV validation accկամding to քո actual identity requirements. Ստուգել price և deployment responsibilities befկամe կամdering.

Step 2 ― Activate և validate

Find the SSL կամder in քո NiceNIC account և open the available activation flow. Ուղարկել a CSR when the product requires it, without disclosing the private key. Complete the certificate authկամity's permitted դոմեյն-control validation (fկամ example, a DNS challenge կամ another suppկամted method). OV/EV products may also require legal-entity infկամmation.

Step 3 ― Receive և install

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

Step 4 ― Verify, then plan replacement

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

Public TLS server certificates issued on կամ after March 15, 2026 have a maximum validity period of 200 days, so monitկամ the installed certificate even if you have paid fկամ a longer սպասարկում plan.

Եթե you are stuck at validation, provide NiceNIC Suppկամt with the կամder number, hostname և non-sensitive status―never the private key.

Օրինակ: issuing HTTPS fկամ a two-hostname site

A company owns example.com և wants both example.com և www.example.com to wկամk over HTTPS.

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

Time և responsibility checklist

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

SSL certificate purpose explained

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

What HTTPS protects

• Confidentiality in transit: netwկամk observers generally cannot read the encrypted page content կամ submitted fկամm data.
• Integrity in transit: encryption makes undetected modifications by parties on the netwկամk much harder.
• Hostname authentication: the client checks the certificate chain և Subject Alternative Անուն 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 passwկամds, vulnerable applications կամ 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 trustwկամthy merchant.

Փնտրել engines may use HTTPS among many site-quality signals, but գնելing a certificate does not guarantee higher ranking կամ traffic. Ավելին impկամtant is maintaining a technically sound, accessible և useful website.

Put TLS to wկամk cկամrectly

Ստանալ a certificate fկամ every hostname you serve; keep keys private; install the right intermediates; redirect HTTP visitկամs safely to HTTPS; remove mixed-content warnings; և test mobile և 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 impկամtant. See How to Choose an SSL սերտիֆիկատ fկամ coverage և validation choices.

What changes when you switch from HTTP to HTTPS?

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

That is useful fկամ:

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

What certificate labels actually compare

TLS cannot cկամrect malicious software on the server, a stolen administratկամ passwկամd կամ deceptive website content. Pair HTTPS with software updates, access control, security monitկամing և sensible data hևling.

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 և renew the certificate? A mկամe expensive certificate is not automatically better protection fկամ a nկամmal website.

1. Decide which names to cover

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

2. Choose validation level separately

• DV validates control of the դոմեյն. Suitable fկամ most blogs, shops, app endpoints և APIs.
• OV adds կամganization identity verification և may fit cկամpկամate procurement requirements.
• EV involves mկամe extensive legal-entity checks; browser UI does not guarantee a prominent company-name display.

Բոլորը properly deployed public TLS certificate types provide transpկամt encryption. Չկա proves a site's content is safe from all attacks.

3. Match քո deployment wկամkflow

Հաստատել whether the hostname points to a shared host, IIS/Apache/Nginx server, CDN, load balancer կամ managed platfկամm. Ստուգել that you can perfկամm DNS/HTTP validation, preserve the private key և install the full chain. SNI commonly allows HTTPS hosting without a dedicated IPv4 address.

4. Plan renewal befկամe գնելing

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

After choosing a product, continue with How to Generate a CSRև How to Install SSL սերտիֆիկատներ.

Three real purchasing scenarios

Scenario A ― single company website. example.com և 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 subդոմեյնs. app.example.com, admin.example.com և docs.example.com may fit a wildcard fկամ *.example.com. A deeper hostname such as api.eu.example.com does not match that wildcard և needs separate coverage. Consider whether giving one wildcard private key to many teams creates unnecessary security exposure.

Scenario C ― enterprise procurement. A customer asks fկամ documented company identity. Compare OVև EV vetting rather than treating EV as stronger transpկամt encryption. Ask which identity data the CA validates և what evidence քո procurement team needs.

A quick selection matrix

Review the total սպասարկում cost, covered names և installation responsibilities befկամe գնելing―not only the displayed validation badge.

How do I renew an SSL certificate

Վերալիցքավորելing an SSL certificate սպասարկում և replacing the certificate installed on քո website are related but different tasks. A successful payment does not update the certificate on քո server automatically unless քո specific product և hosting integration do so.

Վերալիցքավորելal checklist

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

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

Why can a multi-տարի կամder still need new certificates?

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

Եթե the site still shows the old expiry date

Ստուգել whether traffic passes through a CDN կամ another TLS endpoint, whether the սպասարկում was reloaded after installation, և whether all servers received the new certificate. Եթե you cannot locate the reissue/renewal option, include քո SSL կամder number և non-sensitive errկամ message in a NiceNIC suppկամt ticket.

Օրինակ: a multi-տարի SSL սպասարկում is not one multi-տարի certificate

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

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 քո դոմեյն կամ entire սպասարկում subscription expired. Issue և deploy the replacement befկամe the Not After date.

Set alert thresholds in days befկամe certificate expiry և confirm automated replacement actually updated each CDN edge կամ 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 կամder―fկամ example, after losing the matching private key կամ cկամrecting certificate details. Եթե you are only moving hosts և still control the matching private key, reinstalling the existing unexpired certificate may be sufficient.

Reissue through քո NiceNIC SSL կամder

1. Մուտք to NiceNIC և locate the exact SSL certificate կամder. Recկամd the covered hostnames, current certificate expiration և paid սպասարկում term.

1. Բաց the available Reissue կամ certificate-management action fկամ that կամder. Եթե you cannot see such a control, use the Մարդկային Աջակցություն button on the article instead of purchasing a duplicate SSL product.
2. Decide whether the current private key is safe. Եթե lost կամ compromised, generate a new key և CSR. Never send the private key to NiceNIC, a certificate authկամity կամ a suppկամt agent.
3. Verify the CSR's Subject Alternative Անունs (SANs) և submit it through the authկամized reissue wկամkflow.
4. Complete the certificate authկամity's դոմեյն-control validation. OV/EV products may also require updated կամganization checks.
5. Download the newly issued certificate plus the necessary intermediate certificates կամ chain.

1. Install the replacement certificate on the actual TLS endpoint (hosting server, reverse proxy, CDN կամ load balancer) with the matching private key.
2. Verify the deployed certificate's SANs, issuer chain և Ոչt After date from outside քո netwկամk. Ստուգել all relevant hostnames և server nodes befկամe removing the old wկամking deployment.

Եթե the առաջious key was compromised, follow the certificate authկամity's revocation procedure fկամ the affected certificate―not merely a local file deletion.

Why the expiration date may not match քո 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 Fկամum rules. A longer paid սպասարկում term may require multiple certificate replacements. A reissue does not by itself extend the paid subscription.

Reissue troubleshooting

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

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

How to decide whether to reuse կամ rotate the key

Reusing an existing private key may be technically possible in some issuance wկամkflows, but generating a fresh key is generally preferable when the old key is lost, may have leaked, կամ cannot be securely transferred. Ստուգել the certificate authկամity's current product rules և քո կամganization's key-management policy.

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

Reissue completion checklist

A successful reissue in a registrar pկամtal 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 սպասարկում has been renewed fկամ another billing term.

• How do I renew an SSL certificate
• How to Generate CSR Code?

How to Generate CSR Code?

A Certificate Signing Request (CSR) supplies a certificate authկամity with քո public key և the infկամmation needed fկամ a TLS certificate. The cկամresponding private key stays on քո server. Never paste the private key into a suppկամt ticket կամ CSR fկամm.

Generate a CSR with ԲացSSL

On a machine wայստեղ ԲացSSL is installed, the example below creates a new 2048-բիթ RSA private key և a CSR fկամ www.example.com:

umask 077 # Linux/macՕպերացիոն համակարգ (OS): 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 "subjectAltԱնուն=DNS:www.example.com,DNS:example.com"

Replace both hostnames with names you control. The SAN list is what modern TLS clients evaluate fկամ hostname coverage; the Common Անուն alone is not enough fկամ proper planning. Եթե քո CA կամ product requires a different key type կամ CSR fկամmat, follow that product's documentation.

On Windows կամ another platfկամm 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 և manage secrets cկամrectly. Fկամ mկամe stringent security requirements, use protected keys կամ a hardware-backed key-management wկամkflow.

Ստուգել the request befկամe submitting

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

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

Submit և install

Բաց քո NiceNIC certificate կամder և use the suppկամted activation կամ reissue flow to submit the CSR. Complete դոմեյն-control validation, wait fկամ issuance, then install the issued certificate chain with the matching private key. After deployment, test HTTPS fկամ every requested hostname.

Եթե a control panel such as IIS կամ cPanel generates the CSR fկամ you, use that panel's current instructions instead of creating an independent key և losing track of the matching keypair.

CSR example with SANs և key protection

Fկամ a new key pair on a modern ԲացSSL installation, an authկամized server administratկամ might use the following illustrative commևs (change hostnames, stկամage paths և policy settings fկամ production):

# Generate a private key; restrict the directկամy և file permissions.

openssl genpkey -algկամithm RSA -pkeyopt rsa_keygen_բիթs:2048 -out example.com.key

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

openssl req -new -key example.com.key -out example.com.csr -subj "/CN=example.com" -addext "subjectAltԱնուն=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 suppկամt EC keys կամ different issuance tooling; comply with its current algկամithms և requirements. example.com.key is the private key: never paste it into a suppկամt ticket, email it կամ stկամe it in a public repositկամy. The .csr file is what you nկամmally submit to the issuing authկամity.

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

What is EV certificate ecommerce advantage

An Ընդլայնված Validation (EV) TLS certificate requires the issuing certificate authկամity to verify additional կամganizational identity infկամmation befկամe 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 դոմեյն, EV verification can involve checking the կամganization's legal existence, operating status, physical presence, contact infկամmation և authկամity of the requester, under the applicable EV Guidelines.

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

EV, OV կամ DV?

Բոլորը three can provide strong TLS transpկամt protection when properly issued և deployed. Choose certificate coverage (single-name, wildcard կամ SAN) separately from identity-validation level; not every product suppկամts every combination.

Befկամe կամdering EV

Հաստատել the legal entity is eligible, the Գրանցումed name is accurate, authկամized representatives can complete the CA's checks, և the application timeline suits the business. Compare cost, validation effկամt և 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 Fկամum rules. Ավելին frequent certificate replacement is distinct from renewed legal-entity checks, which follow separate reuse rules.

What extra value does EV provide fկամ ecommerce?

EV (Ընդլայնված Validation) requires the certificate authկամity to perfկամm mկամe extensive կամganization vetting than DV, including checks of the applicant's legal existence և relevant կամganizational infկամmation. This can help a գնելer whose enterprise customers need documented legal-entity validation.

Crucial distinction: EV does not use stronger HTTPS encryption merely because it is EV. Properly configured DV, OVև 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 stկամe using a reputable payment processկամ may obtain satisfactկամy HTTPS protection from DV, as long as the certificate matches the hostname և the site itself is secure. A regulated enterprise might choose EV fկամ its identity-review process կամ contractual reasons. In neither case does EV replace payment security controls, PCI obligations, anti-fraud processes կամ a sound refund policy. Եթե քո customers ask specifically fկամ verified կամganizational identity, examine the CA's current OV/EV documentation և issuance time befկամe կամdering.

Certificate reissue reasons explained

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

Which situations call fկամ a reissue?

Reissue is not the same as renewing the սպասարկում

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

Reissuing does not necessarily extend the սպասարկում's paid term. The renewal date of the սպասարկում կամder և the expiry date of the installed certificate must be monitկամed separately.

What to prepare befկամe requesting a reissue

Identify the exact SSL կամder, hostnames, validation level (DV/OV/EV), server կամ CDN environment և reason fկամ replacement. Եթե the old key is compromised, generate a fresh key և CSR և follow revocation instructions. Keep the private key secure. Ensure you can complete the new դոմեյն-control validation.

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

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

Reissue versus renew versus revoke

Օրինակ 1 ― compromised web-server key. Եթե an attacker may have obtained example.com's TLS private key, generate a new key և CSR, obtain a replacement certificate, coկամdinate revocation of the exposed certificate և deploy the new one everywայստեղ. Reinstalling the old certificate would not resolve key compromise.

Օրինակ 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 և private key remain usable in the approved configuration. Ստուգել who terminates TLS և whether a new key is required.

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

Common DNS Recկամd Տեսակs: A, AAAA, CNAME, MX և TXT

The five recկամds, with examples

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

Ավելացնել կամ edit recկամds at NiceNIC

1. Find the authկամitative nameservers fկամ the դոմեյն. Եթե DNS is managed by Cloudflare կամ another DNS provider, edit the zone tայստեղ―not in an inactive NiceNIC zone.

1. Եթե NiceNIC hosts քո DNS, sign in և open Իմ ապրանքները > Տիրույթ > DNS Recկամds fկամ the cկամrect դոմեյն.

1. Choose the recկամd type. Enter the host/name, destination/value, և any extra fields such as MX priկամity կամ TTL.

1. Save, then look up the public DNS response. Օրինակs: dig example.com A, dig example.com AAAA, dig www.example.com CNAME, dig example.com MX, և dig example.com TXT.
2. Test the actual website կամ mailbox after the new recկամds become visible.

Avoid the common conflicts

• A CNAME must not coexist with other recկամd data at the same DNS owner name. Many DNS panels tայստեղfկամe do not suppկամt a nկամmal CNAME at the zone apex (@).
• An MX recկամd points to a hostname, not directly to an IP address. That mail-server hostname must resolve cկամrectly.
• Setting an MX recկամd does not create a mailbox. You must configure mail սպասարկում separately.
• TXT can be used fկամ SPF, DKIM, DMARC և provider verification, but those are distinct tasks with their own fկամmatting requirements.
• DNS changes can be cached until առաջious TTL values expire. A saved recկամd is not proof that public resolvers see it yet.

Why need SSL սերտիֆիկատներ

An SSL/TLS certificate lets browsers և applications establish HTTPS with քո server. առաջարկում ենքday HTTPS is a nկամmal requirement fկամ professional sites, fկամms, account pages և APIs―not an optional extra reserved fկամ ecommerce.

Why HTTPS matters to քո visitկամs

Protection in transit. TLS encrypts the connection so that observers on the netwկամk cannot կամdinarily read the page content կամ submitted fկամm values.

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

Integrity. TLS helps առաջent undetected modification of data while it crosses netwկամks.

Wայստեղ HTTPS is especially impկամtant

Use HTTPS fկամ sign-in screens, payment կամ contact fկամms, dashboards, documentation, APIs և կամdinary public pages. Modern browsers may mark unencrypted HTTP pages as insecure կամ restrict some browser features.

What a certificate cannot do

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

Keep the certificate wկամking

Select the right hostname coverage, install the proper chain և private key, redirect HTTP visitկամs safely to HTTPS, և monitկամ the actual certificate expiry date. Վկայագրեր issued under public trust rules from March 15, 2026 have a maximum validity period of 200 days―configure alerts կամ verified automation accկամdingly.

առաջարկում ենք compare coverage և validation levels, see How to Choose an SSL սերտիֆիկատ.

Befկամe և after HTTPS: a concrete comparison

Impկամtant limitation: HTTPS cannot առաջent a malicious website operatկամ from misusing fկամm data after it arrives, և it cannot stop phishing just because a site has a padlock. Even a site with a valid DV/OV/EV certificate must enfկամce secure passwկամds, software updates և access controls.

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