NAMEOCSP_REQUEST_new, OCSP_REQUEST_free, OCSP_request_add0_id, OCSP_request_sign, OCSP_request_add1_cert, OCSP_request_onereq_count, OCSP_request_onereq_get0 − OCSP request functions
SYNOPSIS​ #include <openssl/ocsp.h> ​ ​ OCSP_REQUEST *OCSP_REQUEST_new(void); ​ void OCSP_REQUEST_free(OCSP_REQUEST *req); ​ ​ OCSP_ONEREQ *OCSP_request_add0_id(OCSP_REQUEST *req, OCSP_CERTID *cid); ​ ​ int OCSP_request_sign(OCSP_REQUEST *req, ​ X509 *signer, EVP_PKEY *key, const EVP_MD *dgst, ​ STACK_OF(X509) *certs, unsigned long flags); ​ ​ int OCSP_request_add1_cert(OCSP_REQUEST *req, X509 *cert); ​ ​ int OCSP_request_onereq_count(OCSP_REQUEST *req); ​ OCSP_ONEREQ *OCSP_request_onereq_get0(OCSP_REQUEST *req, int i);
DESCRIPTION​OCSP_REQUEST_new() allocates and returns an empty OCSP_REQUEST structure. ​OCSP_REQUEST_free() frees up the request structure req. ​OCSP_request_add0_id() adds certificate ID cid to req. It returns the OCSP_ONEREQ structure added so an application can add additional extensions to the request. The id parameter MUST NOT be freed up after the operation. ​OCSP_request_sign() signs OCSP request req using certificate ​signer, private key key, digest dgst and additional certificates ​certs. If the flags option OCSP_NOCERTS is set then no certificates will be included in the request. ​OCSP_request_add1_cert() adds certificate cert to request req. The application is responsible for freeing up cert after use. ​OCSP_request_onereq_count() returns the total number of OCSP_ONEREQ structures in req. ​OCSP_request_onereq_get0() returns an internal pointer to the OCSP_ONEREQ contained in req of index i. The index value i runs from 0 to OCSP_request_onereq_count(req) − 1.
RETURN VALUES​OCSP_REQUEST_new() returns an empty OCSP_REQUEST structure or NULL if an error occurred. ​OCSP_request_add0_id() returns the OCSP_ONEREQ structure containing cid or NULL if an error occurred. ​OCSP_request_sign() and OCSP_request_add1_cert() return 1 for success and 0 for failure. ​OCSP_request_onereq_count() returns the total number of OCSP_ONEREQ structures in req. ​OCSP_request_onereq_get0() returns a pointer to an OCSP_ONEREQ structure or NULL if the index value is out or range.
NOTESAn OCSP request structure contains one or more OCSP_ONEREQ structures corresponding to each certificate. ​OCSP_request_onereq_count() and OCSP_request_onereq_get0() are mainly used by ​OCSP responders.
EXAMPLESCreate an OCSP_REQUEST structure for certificate cert with issuer ​issuer: ​ OCSP_REQUEST *req; ​ OCSP_ID *cid; ​ ​ req = OCSP_REQUEST_new(); ​ if (req == NULL) ​ /* error */ ​ cid = OCSP_cert_to_id(EVP_sha1(), cert, issuer); ​ if (cid == NULL) ​ /* error */ ​ ​ if (OCSP_REQUEST_add0_id(req, cid) == NULL) ​ /* error */ ​ ​ /* Do something with req, e.g. query responder */ ​ ​ OCSP_REQUEST_free(req);
