#include <gnutls/pkcs11.h> int gnutls_pkcs11_get_raw_issuer_by_subject_key_id(const char * url, const gnutls_datum_t * dn, const gnutls_datum_t * spki, gnutls_datum_t * issuer, gnutls_x509_crt_fmt_t fmt, unsigned int flags);
const char * url A PKCS 11 url identifying a token const gnutls_datum_t * dn is the DN to search for (may be NULL) const gnutls_datum_t * spki is the subject key ID to search for gnutls_datum_t * issuer Will hold the issuer if any in an allocated buffer. gnutls_x509_crt_fmt_t fmt The format of the exported issuer. unsigned int flags Use zero or flags from GNUTLS_PKCS11_OBJ_FLAG.
This function will return the certificate with the given DN and spki , if it is stored in the token. By default only marked as trusted issuers are returned. If any issuer should be returned specify GNUTLS_PKCS11_OBJ_FLAG_RETRIEVE_ANY in flags . The name of the function includes issuer because it can be used to discover issuers of certificates.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
