gnutls_certificate_verify_peers2 - API function
#include <gnutls/gnutls.h>
int gnutls_certificate_verify_peers2(gnutls_session_t session,
unsigned int * status);
gnutls_session_t session
is a gnutls session
unsigned int * status
is the output of the verification
This function will verify the peer's certificate and store the status
in the status variable as a bitwise or'd gnutls_certificate_status_t
values or zero if the certificate is trusted. Note that value in
status is set only when the return value of this function is success
(i.e, failure to trust a certificate does not imply a negative return
value). The default verification flags used by this function can be
overridden using gnutls_certificate_set_verify_flags().
This function will take into account the OCSP Certificate Status TLS
extension, as well as the following X.509 certificate extensions:
Name Constraints, Key Usage, and Basic Constraints (pathlen).
To avoid denial of service attacks some default upper limits
regarding the certificate key size and chain size are set. To
override them use gnutls_certificate_set_verify_limits().
Note that you must also check the peer's name in order to check if
the verified certificate belongs to the actual peer, see
gnutls_x509_crt_check_hostname(), or use
gnutls_certificate_verify_peers3().
GNUTLS_E_SUCCESS (0) when the validation is performed, or a negative
error code otherwise. A sucessful error code means that the status
parameter must be checked to obtain the validation status.
