gnutls_ocsp_status_request_is_checked - API function
unsigned gnutls_ocsp_status_request_is_checked(gnutls_session_t session, unsigned int flags);
- gnutls_session_t session
is a gnutls session
- unsigned int flags
should be zero or GNUTLS_OCSP_SR_IS_AVAIL
When flags are zero this function returns non-zero if a valid OCSP status
response was included in the TLS handshake. That is, an OCSP status response
which is not too old, superseded or marks the certificate as revoked.
It returns zero otherwise.
When the flag GNUTLS_OCSP_SR_IS_AVAIL is specified, the function
returns non-zero if an OCSP status response was included in the handshake
even if it was invalid. Otherwise, if no OCSP status response was included,
it returns zero. The GNUTLS_OCSP_SR_IS_AVAIL flag was introduced in GnuTLS 3.4.0.
This is a helper function when needing to decide whether to perform an
explicit OCSP validity check on the peer's certificate. Should be called after
any of gnutls_certificate_verify_peers*() are called.
This function is always usable on client side, but on server side only
under TLS 1.3, which is the first version of TLS that allows cliend-side OCSP
Non-zero if the response was valid, or a zero if it wasn't sent,
or sent and was invalid.
