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);

should contain a gnutls_ocsp_req_t type
Specifies which extension OID to get. Use (0) to get the first one.
output variable with gnutls_digest_algorithm_t hash algorithm
output buffer with hash of issuer's DN
output buffer with hash of issuer's public key
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.
