Name

gnutls_pkcs11_crt_is_known — API function

Synopsis

#include <gnutls/pkcs11.h>
int gnutls_pkcs11_crt_is_known( const char * url,
  gnutls_x509_crt_t cert,
  unsigned int flags);
 

ARGUMENTS

const char * url

A PKCS 11 url identifying a token

gnutls_x509_crt_t cert

is the certificate to find issuer for

unsigned int flags

Use zero or flags from GNUTLS_PKCS11_OBJ_FLAG.

DESCRIPTION

This function will check whether the provided certificate is stored in the specified token. This is useful in combination with GNUTLS_PKCS11_OBJ_FLAG_RETRIEVE_TRUSTED or GNUTLS_PKCS11_OBJ_FLAG_RETRIEVE_DISTRUSTED, to check whether a CA is present or a certificate is blacklisted in a trust PKCS 11 module.

This function can be used with a url of "pkcs11:", and in that case all modules will be searched. To restrict the modules to the marked as trusted in p11−kit use the GNUTLS_PKCS11_OBJ_FLAG_PRESENT_IN_TRUSTED_MODULE flag.

Note that the flag GNUTLS_PKCS11_OBJ_FLAG_RETRIEVE_DISTRUSTED is specific to p11−kit trust modules.

RETURNS

If the certificate exists non−zero is returned, otherwise zero.

SINCE

3.3.0
