gnutls_ocsp_resp_t resp

should contain a gnutls_ocsp_resp_t structure

unsigned indx

Specifies response number 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

unsigned int * cert_status

a certificate status, a gnutls_ocsp_cert_status_t enum.

time_t * this_update

time at which the status is known to be correct.

time_t * next_update

when newer information will be available, or (time_t)−1 if unspecified

time_t * revocation_time

when cert_status is GNUTLS_OCSP_CERT_REVOKED, holds time of revocation.

unsigned int * revocation_reason

revocation reason, a gnutls_x509_crl_reason_t enum.


This function will return the certificate information of the indx 'ed response in the Basic OCSP Response resp . The information returned corresponds to the OCSP SingleResponse structure except the final singleExtensions.

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


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.
