NAME         top

       gnutls_session_set_verify_cert - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       void gnutls_session_set_verify_cert(gnutls_session_t session,
       const char * hostname, unsigned flags);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls session

       const char * hostname
                   is the expected name of the peer; may be NULL

       unsigned flags
                   flags for certificate verification --
                   gnutls_certificate_verify_flags

DESCRIPTION         top

       This function instructs GnuTLS to verify the peer's certificate
       using the provided hostname. If the verification fails the
       handshake will also fail with
       GNUTLS_E_CERTIFICATE_VERIFICATION_ERROR. In that case the
       verification result can be obtained using
       gnutls_session_get_verify_cert_status().

       The  hostname pointer provided must remain valid for the lifetime
       of the session. More precisely it should be available during any
       subsequent handshakes. If no hostname is provided, no hostname
       verification will be performed. For a more advanced verification
       function check gnutls_session_set_verify_cert2().

       If  flags is provided which contain a profile, this function
       should be called after any session priority setting functions.

       The gnutls_session_set_verify_cert() function is intended to be
       used by TLS clients to verify the server's certificate.
