-B<WARNING: this documentation is preliminary and subject to change.>
-
The Online Certificate Status Protocol (OCSP) enables applications to
determine the (revocation) state of an identified certificate (RFC 2560).
This specifies the current issuer certificate. This option can be used
multiple times. The certificate specified in B<filename> must be in
-PEM format.
