dane_verify_session_crt(3)          gnutls          dane_verify_session_crt(3)


NAME

       dane_verify_session_crt - API function


SYNOPSIS

       #include <gnutls/dane.h>

       int dane_verify_session_crt(dane_state_t s, gnutls_session_t session,
       const char * hostname, const char * proto, unsigned int port, unsigned
       int sflags, unsigned int vflags, unsigned int * verify);


ARGUMENTS

       dane_state_t s
                   A DANE state structure (may be NULL)

       gnutls_session_t session
                   A gnutls session

       const char * hostname
                   The hostname associated with the chain

       const char * proto
                   The protocol of the service connecting (e.g. tcp)

       unsigned int port
                   The port of the service connecting (e.g. 443)

       unsigned int sflags
                   Flags for the initialization of  s (if NULL)

       unsigned int vflags
                   Verification flags; an OR'ed list of dane_verify_flags_t.

       unsigned int * verify
                   An OR'ed list of dane_verify_status_t.


DESCRIPTION

       This function will verify session's certificate chain against the CA
       constrains and/or the certificate available via DANE.  See
       dane_verify_crt() for more information.

       This will not verify the chain for validity; unless the DANE
       verification is restricted to end certificates, this must be be
       performed separately using gnutls_certificate_verify_peers3().


RETURNS

       a negative error code on error and DANE_E_SUCCESS (0) when the DANE
       entries were successfully parsed, irrespective of whether they were
       verified (see  verify for that information). If no usable entries were
       encountered DANE_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
