gnutls_ocsp_req_get_cert_id - API function

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.
