How to Reissue Your SSL Certificate on ComodoSSLStore.com

Re-issue Reasons

Over the course of your SSL certificate's lifespan, it may be necessary for you to reissue it at some point. This can happen for a number of reasons:

  • Your private key has been compromised
  • You are adding/removing SAN's
  • Industry updates
  • Changing hashing algorithms
  • Moving servers

The good news is that, outside of time, it probably won't cost you anything–most SSL certificates come with unlimited free reissuances for their entire lifespan. Below you will find instructions on how to reissue your active certificate(s) from your SSL providers control panel.

1. Generate CSR

Before you re-issue your SSL Certificate, make sure that you have the appropriate CSR. For that, you may use either one of the following:

  • Original CSR– this is the old CSR you used to issue the certificate previously (note: only do this if you still have access to the Private Key that was generated with that CSR). 
  • New CSR– create a new CSR using either an online tool or directly from your webserver.

Note: If you generate a new CSR, make sure you save your Private key in a safe place. You will need it to install the re-validated certificate later.

The email address listed on the whois for the domain in question

File Based Authentication – Selecting this option indicates that you will upload a .txt file based on the hash values of your CSR to the root folder of your website. The file will be provided to you once you submit the reissue and you will need to upload it to the following path:

  • https://><domain.com>/.well-known/pki-validation/<MD5hash>.txt

DNS Based Authentication – Selecting this options allows you to create a DNS record using the hash values provided by the Certificate Authority after the request is submitted.

7. Paste CSR

Copy and paste your CSR into the area indicated below.

8. Select Server Type

If you don't know the kind of server the certificate will be installed on, just select Other. Once you've selected, click "Continue."

9. Confirm Details and Submit Re-Issue Request

You will be taken to another page to confirm the certificate details. If you selected e-mail based verification, you'll select the e-mail, and you'll confirm contact details and agree to the subscriber agreement.

Once everything is confirmed, select "Continue" and your reissue request will be submitted.

10. Re-Validate

When you request a certificate to be re-issued, the issuing certificate authority must go through the validation process again. The good news is that they were already able to complete this process for your order previously, so re-validation typically goes very quickly and smoothly. However, if you are reissuing a type of certificate that requires a final verification call (OV or EV), the CA will need to perform that call again. Keep an ear out for that call, if you don't receive it within 24 hours, contact support.

After you complete the validation process and have received the reissued SSL Certificate, you can proceed to installing the new certificate.
