gnutls_certificate_verify_peers2(3)

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 try to verify the peer's certificate and return its status (trusted, invalid etc.). The value of status should be one or more of the gnutls_certificate_status_t enumerated elements bitwise or'd. 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. This function uses gnutls_x509_crt_list_verify() with the CAs in the credentials as trusted CAs.

RETURNS
a negative error code on error and GNUTLS_E_SUCCESS (0) on success.
