7.4. Checking the Revocation Status of a Certificate

The revocation status of a certificate is checked by submitting the certificate in its base-64 encoded format to the OCSP, as follows:

  1. Copy the base-64-encoded certificate, including the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- marker lines, to the clipboard or a text file.

    The certificate looks similar to this example: 

    -----BEGIN CERTIFICATE-----
