The short answer is that while yes you can reuse the CSR, it doesn't mean you should.. It's worth considering that encryption methods can improve over time (e.g., generating RSA keys @ 2048 or 4096 vs 1024 awhile back, sha256 vs. sha512, etc) so it's probably best to just generate a new one considering how trivial it is and increasing the private key strength if it's outdated. Since the new SSL certificate would be issued to the same domain, users likely wouldn't notice anything since only the certificate would change (i.e., the green lock will still be displayed), which users typically do not view anyway, especially between pages on the same site. Additionally, if you double-click the certificate, you will see the message: "You have a private key that corresponds to this certificate." You can now refresh the list of server certificates in IIS Manager or Exchange Management Console to see the certificate there. The same instructions may be used if the certificate was deleted from the server. I open IIS6, click Properties on the website I want to update (it already has the old SSL Cert on it). Click on the Directory Security tab then the Server Certificate... button. Now, I am presented with the following options: * Renew the current certificate - was done manually through GoDaddy and no pending renewal was ever issued. What is a Wildcard SSL Certificate? Easy to manage and flexible, a Subject Alternative Names (SANs) secured Wildcard is a top choice for organizations managing multiple sites hosted across numerous subdomains. With a DigiCert Wildcard, you can issue copies of your certificate on as many servers as you want, each of which is assigned its own private key.
