gnutls_ocsp_req_get_cert_id(3)

NAME
gnutls_ocsp_req_get_cert_id - API function

SYNOPSIS
#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);

ARGUMENTS

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

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.
