Renew Windows SSL certificate when no key available

This tutorial along with Extract SSL certificate and key from PFX file will help you to migrate renew Windows SSL certificate when no certificate key is available.

Here a key factor is how your certificate was installed. In Migrate (move) SSL certificate from Windows to Linux we discussed how you will not be able to export a certificate if ‘Mark this key as exportable‘ option is not checked during the certificate installation.
Well I hope your case is not the one I described, otherwise the only options are to ask the certificate authority for the key, or to purchase new certificate.

In order to have your Windows SSL renewed, there are three steps that must be accomplished:

1. The existing Windows SSL certificate must be exported. If you are not aware of the process, please read Export PFX file in Windows from IIS or Active Directory .

2. The exported PFX certificate must be separated to SSL certificate and key: This is the first tutorial I mentioned: Extract SSL certificate and key from PFX file

3. And the final part will be to merge the new certificate with the exported key, which you can read how, can be done in: Merge SSL certificate and key in PFX file.

Once the certificate is merged in PFX file, login to the Windows server where you have to set it for the domain.

Depending on the server configuration you have to put the certificate into the active directory Certificate repository.
