About certificate validity

Every certificate has a validity period. After the end of the validity period, the certificate is no longer considered an acceptable or usable credential.

You can renew the certificate either with the same key set that you used before, or with a new key set.

Before you renew a certificate, you must know the issuing certification authority.

  • Optionally, if you want a new public key and private key pair for the certificate, you must know the cryptographic service provider (CSP) that should be used to generate the key pair.

For more information, see Renew a Certificate with a New Key and Renew a Certificate with the Same Key.

In addition, you can renew certificates issued from both enterprise certification authorities and stand-alone certification authorities with the Certificate Services Web pages by pasting in the contents of a PKCS #7 file. For more information, see Request a Certificate Using a PKCS #10 or PKCS #7 File.
