gnutls_ocsp_req_get_cert_id − API function
#include <gnutls/ocsp.h>
int gnutls_ocsp_req_get_cert_id(gnutls_ocsp_req_const_t req, unsigned indx, gnutls_digest_algorithm_t * digest, gnutls_datum_t * issuer_name_hash, gnutls_datum_t * issuer_key_hash, gnutls_datum_t * serial_number);
gnutls_ocsp_req_const_t req
should contain a gnutls_ocsp_req_t type
unsigned indx
Specifies which extension OID to get. Use (0) to get the first one.
gnutls_digest_algorithm_t * digest
output variable with gnutls_digest_algorithm_t hash algorithm
gnutls_datum_t * issuer_name_hash
output buffer with hash of issuer’s DN
gnutls_datum_t * issuer_key_hash
output buffer with hash of issuer’s public key
gnutls_datum_t * serial_number
output buffer with serial number of certificate to check
This function
will return the certificate information of the
indx ’ed request in the OCSP request. The
information returned corresponds to the CertID
structure:
<informalexample><programlisting> CertID |
::= SEQUENCE { hashAlgorithm AlgorithmIdentifier, issuerNameHash OCTET STRING, −− Hash of Issuer’s DN issuerKeyHash OCTET STRING, −− Hash of Issuers public key serialNumber |
CertificateSerialNumber } </programlisting></informalexample> |
Each of the pointers to output variables may be NULL to indicate that the caller is not interested in that value.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error code is returned. If you have reached the last CertID available GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE will be returned.
