API function


#include <gnutls/x509.h>

int gnutls_x509_crt_verify(gnutls_x509_crt_t cert, const gnutls_x509_crt_t * CA_list, unsigned CA_list_length, unsigned int flags, unsigned int * verify);


gnutls_x509_crt_t cert

is the certificate to be verified

const gnutls_x509_crt_t * CA_list

is one certificate that is considered to be trusted one

unsigned CA_list_length

holds the number of CA certificate in CA_list

unsigned int flags

Flags that may be used to change the verification algorithm. Use OR of the gnutls_certificate_verify_flags enumerations.

unsigned int * verify

will hold the certificate verification output.


This function will try to verify the given certificate and return its status. Note that a verification error does not imply a negative return status. In that case the  verify status is set.

The details of the verification are the same as in gnutls_x509_trust_list_verify_crt2().


On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
