NAME
gnutls_certificate_verify_peers2 - API function
SYNOPSIS
#include <gnutls/gnutls.h>
int gnutls_certificate_verify_peers2(gnutls_session_t session, unsigned
int * status);
ARGUMENTS
gnutls_session_t session
is a gnutls session
unsigned int * status
is the output of the verification
DESCRIPTION
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 sta‐
tus 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 overriden
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_ver‐
ify_peers3().
RETURNS
a negative error code on error and GNUTLS_E_SUCCESS (0) on success.
