gnutls_certificate_verify_peers2(3) gnutls gnutls_certificate_verify_peers2(3)

NAME
       gnutls_certificate_verify_peers2	 - return the peer's certificate veri‐
       fication 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.

       This  function  uses  gnutls_x509_crt_list_verify() with the 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.

RETURNS
       a negative error code on error and zero on success.
