NAME         top

       gnutls_ocsp_req_get_cert_id - API function

SYNOPSIS         top

       #include <gnutls/ocsp.h>

       int gnutls_ocsp_req_get_cert_id(gnutls_ocsp_req_t req, unsigned indx,
       gnutls_digest_algorithm_t * digest, gnutls_datum_t *
       issuer_name_hash, gnutls_datum_t * issuer_key_hash, gnutls_datum_t *

ARGUMENTS         top

       gnutls_ocsp_req_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

       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

DESCRIPTION         top

       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 }

       Each of the pointers to output variables may be NULL to indicate that
       the caller is not interested in that value.

RETURNS         top

       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.
