NAME

       gnutls_ocsp_req_get_cert_id - API function

SYNOPSIS

       #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 * serial_number);

ARGUMENTS

       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 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

DESCRIPTION

       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.

RETURNS

       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.
