What is the difference between SSL renew and SSL reissue? ›

An SSL renewal will not typically require you to generate a new CSR. Choose the renewal option if you want to renew your certificate and no other details have changed. A reissue can be done if you've lost your private key, or your server details have changed.

The reissue requires if you have lost a private key, changing your server, or for any other reason... The process of renewal is almost the same as placing a New Order. You will need to submit new or original CSR code, pass the verification process and reinstall new files on the server...

When your current certificate is about to expire, a Renewal is required. A Revoke & Replace (Reissue) is when you cancel a current, valid certificate and request a new one.

Once the certificate re-issued, the certificate authority will send you a new certificate. Install the new certificate and private key on your server, or replace the existing one to deploy the new certificate. The old certificate will stay active until the expiration date.

SSL renewal keeps your encryption up to date, which makes everyone safer. SSL certificates have expiration dates hardcoded into them. When they expire, web browsers will warn their users about your website. The reason SSL certificates expire is to keep your encryption up to date.

An SSL certificate is vital to maintaining trust between your website and your clients. Using an expired certificate makes clients vulnerable to cyber attacks, which can break their trust.

A new cert is issued, but it doesn't overwrite the old one. And if the old one were overwritten, what then? It can't be used again, so (once again) there's no reason to revoke it. Again, the only reason to revoke a cert is if you suspect the private key has been compromised.

Reissue means issuing a certificate once again while retaining the end date of that certificate. Certificate reissuance through this mechanism is completely free and available for the entire period of certificate validity.

Reissuing is when the airlines print an entirely new ticket with your changed travel date and flight number. Revalidation is when the date for your flight is changed in the airline system. You can just present your original ticket at the airport for check in, even though your new itinerary is different.

The reason you have to renew is two-fold. Perhaps most importantly, shorter lifespans aid in the proliferation of new standards, algorithms and ciphers. Encryption is advancing every day. Changing out certificates regularly keeps your encryption up to date.

How often should I renew my SSL certificate? ›

Most SSL certificates expire after one to two years, depending on the type of certificate you're using and your certificate authority (CA), the organization that issued your SSL certificate. A notable exception to this is the popular CA Let's Encrypt, whose certificates expire after 90 days.

In order to reissue an SSL certificate, you must either locate the original CSR saved on your server or make a new one (recommended), log into your control panel and re-submit it to the Certificate Authority (CA). Some certificates may require you to re-complete a step of the validation process as well.

Once the new certificate (the renewal) is issues, it must be installed in place of the existing one. Both certificate and private key must be replaced on the server.

SSL certificates expire at maximum 398 days from their issuance date, but most CAs will set their expiration date sooner, offentimes around 395 days. It is important to renew any of them BEFORE they expire.

How to automate SSL/TLS certificate renewal. Automatic SSL certificate renewal involves setting up a system to handle the renewal process without manual intervention. It uses tools or services to generate new CSRs, submit them to CAs, complete the validation process, and install the renewed certificate on the server.

Card replacement, you get a new number and expiration date. Reissue, is the same number with a different expiration date.

To renew an SSL/TLS certificate, you'll need to generate a new CSR.
