Such an object is used inside .Vt OCSP_BASICRESP . .Fn OCSP_RESPDATA_free frees .Fa respdata . .Pp .Fn OCSP_RESPID_new allocates and initializes an empty .Vt OCSP_RESPID object, representing an ASN.1 .Vt ResponderID structure defined in RFC 6960. Such an object is used inside .Vt OCSP_RESPDATA . .Fn OCSP_RESPID_free frees .Fa respid . .Pp .Fn OCSP_response_create creates an .Vt OCSP_RESPONSE object for .Fa status and optionally including the basic response .Fa bs . .Pp .Fn OCSP_response_status returns the OCSP response status of .Fa resp . It returns one of the values .Dv OCSP_RESPONSE_STATUS_SUCCESSFUL , .Dv OCSP_RESPONSE_STATUS_MALFORMEDREQUEST , .Dv OCSP_RESPONSE_STATUS_INTERNALERROR , .Dv OCSP_RESPONSE_STATUS_TRYLATER , .Dv OCSP_RESPONSE_STATUS_SIGREQUIRED , or .Dv OCSP_RESPONSE_STATUS_UNAUTHORIZED . .Pp .Fn OCSP_response_status_str converts one of the .Fa status codes returned by .Fn OCSP_response_status to a string consisting of one word. .Pp .Fn OCSP_response_get1_basic decodes and returns the .Vt OCSP_BASICRESP object contained in .Fa resp . It is only called if the status of a response is .Dv OCSP_RESPONSE_STATUS_SUCCESSFUL . .Pp .Fn OCSP_basic_sign signs the OCSP response .Fa bs using the certificate .Fa signer , the private key .Fa key , the digest .Fa dgst , and the additional certificates .Fa certs . If the .Fa flags option .Dv OCSP_NOCERTS is set, then no certificates will be included in the request. If the .Fa flags option .Dv OCSP_RESPID_KEY is set, then the responder is identified by key ID rather than by name. .Sh RETURN VALUES .Fn OCSP_RESPONSE_new and .Fn OCSP_response_create return a pointer to an .Vt OCSP_RESPONSE object or .Dv NULL if an error occurred. .Pp .Fn OCSP_BASICRESP_new and .Fn OCSP_response_get1_basic return a pointer to an .Vt OCSP_BASICRESP object or .Dv NULL if an error occurred. .Pp .Fn OCSP_RESPBYTES_new , .Fn OCSP_RESPDATA_new , and .Fn OCSP_RESPID_new return a pointer to an empty .Vt OCSP_RESPBYTES , .Vt OCSP_RESPDATA , or .Vt OCSP_RESPID object, respectively, or .Dv NULL if an error occurred. .Pp .Fn OCSP_response_status returns a status value. .Pp .Fn OCSP_response_status_str returns a pointer to a static string. .Pp .Fn OCSP_basic_sign return 1 on success or 0 on failure. .Sh SEE ALSO .Xr EVP_DigestInit 3 , .Xr OCSP_cert_to_id 3 , .Xr OCSP_request_add1_nonce 3 , .Xr OCSP_REQUEST_new 3 , .Xr OCSP_resp_find_status 3 , .Xr OCSP_sendreq_new 3 .Sh STANDARDS RFC 6960: X.509 Internet Public Key Infrastructure Online Certificate Status Protocol, section 4.2: Response Syntax .Sh HISTORY These functions first appeared in OpenSSL 0.9.7 and have been available since .Ox 3.2 .
