Embedding the signing certificate's revocation status in a document allows recipients to validate certificates (signatures) while offline and speeds up the revocation checking process. Moreover, if a certificate is revoked or expired at some time after signing, embedded revocation information enables the application to determine if a certificate was valid at the time of signing so that the signature status will remain valid. Note: Revocation checking occurs immediately after signing as well as during signature validation. If the revocation status is not embedded in a signature, the application looks in the locally stored certificate revocation list cache. If it is not there, the application goes online to complete the check.
