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.
