gnutls_x509_crt_list_verify − API function


#include <gnutls/x509.h>

int gnutls_x509_crt_list_verify(const gnutls_x509_crt_t * cert_list, int cert_list_length, const gnutls_x509_crt_t * CA_list, int CA_list_length, const gnutls_x509_crl_t * CRL_list, int CRL_list_length, unsigned int flags, unsigned int * verify);


const gnutls_x509_crt_t * cert_list

is the certificate list to be verified

int cert_list_length

holds the number of certificate in cert_list

const gnutls_x509_crt_t * CA_list

is the CA list which will be used in verification

int CA_list_length

holds the number of CA certificate in CA_list

const gnutls_x509_crl_t * CRL_list

holds a list of CRLs.

int CRL_list_length

the length of CRL 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 list and return its status. If no flags are specified (0), this function will use the basicConstraints ( PKIX extension. This means that only a certificate authority is allowed to sign a certificate.

You must also check the peer’s name in order to check if the verified certificate belongs to the actual peer.

The certificate verification output will be put in verify and will be one or more of the gnutls_certificate_status_t enumerated elements bitwise or’d. For a more detailed verification status use gnutls_x509_crt_verify() per list element.


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