gnutls_certificate_verify_peers2(3) gnutls gnutls_certificate_verify_peers2(3)
NAME
gnutls_certificate_verify_peers2 - This function returns the peer's
certificate verification status
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.
Returns a negative error code on error and zero on success.
This is the same as gnutls_x509_verify_certificate() and uses the
loaded CAs in the credentials as trusted CAs.
Note that some commonly used X.509 Certificate Authorities are still
using Version 1 certificates. If you want to accept them, you need to
call gnutls_certificate_set_verify_flags() with, e.g., GNUTLS_VER‐
IFY_ALLOW_X509_V1_CA_CRT parameter.
