How do I re-key my SSL certificate?

This article will explain how you can re-key your SSL certificate.

Re-keying an SSL certificate is the process of creating a new private key for your certificate. You may wish to re-key your SSL certificate for any of the following reasons:

  • You’ve lost your private key
  • You want to change the domain name associated with your SSL certificate
  • Your server keeps crashing
  • You’ve moved your website to a different server

When you create a new private key, your certificate’s original key will become invalidated, which means that you’ll need to install your re-keyed certificate within the next 72 hours. To do this, simply follow the instructions outlined below:

Step 1 of 8

Start by generating a new certificate signing request (CSR).

Shortly after you’ve done this, you’ll receive an email from us informing you that your newly re-keyed certificate is available.

Once you receive this email, you’ll need to download and install your certificate within 72 hours in order to keep your server secure. You may also have to verify your certificate request as well, provided you receive an email from us requesting this.
