It returns 35the B<OCSP_ONEREQ> structure added so an application can add additional 36extensions to the request. The B<id> parameter B<MUST NOT> be freed up after 37the operation. 38 39OCSP_request_sign() signs OCSP request B<req> using certificate 40B<signer>, private key B<key>, digest B<dgst> and additional certificates 41B<certs>. If the B<flags> option B<OCSP_NOCERTS> is set then no certificates 42will be included in the request. 43 44OCSP_request_add1_cert() adds certificate B<cert> to request B<req>. The 45application is responsible for freeing up B<cert> after use. 46 47OCSP_request_onereq_count() returns the total number of B<OCSP_ONEREQ> 48structures in B<req>. 49 50OCSP_request_onereq_get0() returns an internal pointer to the B<OCSP_ONEREQ> 51contained in B<req> of index B<i>. The index value B<i> runs from 0 to 52OCSP_request_onereq_count(req) - 1. 53 54=head1 RETURN VALUES 55 56OCSP_REQUEST_new() returns an empty B<OCSP_REQUEST> structure or B<NULL> if 57an error occurred. 58 59OCSP_request_add0_id() returns the B<OCSP_ONEREQ> structure containing B<cid> 60or B<NULL> if an error occurred. 61 62OCSP_request_sign() and OCSP_request_add1_cert() return 1 for success and 0 63for failure. 64 65OCSP_request_onereq_count() returns the total number of B<OCSP_ONEREQ> 66structures in B<req> and -1 on error. 67 68OCSP_request_onereq_get0() returns a pointer to an B<OCSP_ONEREQ> structure 69or B<NULL> if the index value is out or range. 70 71=head1 NOTES 72 73An OCSP request structure contains one or more B<OCSP_ONEREQ> structures 74corresponding to each certificate. 75 76OCSP_request_onereq_count() and OCSP_request_onereq_get0() are mainly used by 77OCSP responders. 78 79=head1 EXAMPLES 80 81Create an B<OCSP_REQUEST> structure for certificate B<cert> with issuer 82B<issuer>: 83 84 OCSP_REQUEST *req; 85 OCSP_ID *cid; 86 87 req = OCSP_REQUEST_new(); 88 if (req == NULL) 89 /* error */ 90 cid = OCSP_cert_to_id(EVP_sha1(), cert, issuer); 91 if (cid == NULL) 92 /* error */ 93 94 if (OCSP_REQUEST_add0_id(req, cid) == NULL) 95 /* error */ 96 97 /* Do something with req, e.g. query responder */ 98 99 OCSP_REQUEST_free(req); 100 101=head1 SEE ALSO 102 103L<crypto(7)>, 104L<OCSP_cert_to_id(3)>, 105L<OCSP_request_add1_nonce(3)>, 106L<OCSP_resp_find_status(3)>, 107L<OCSP_response_status(3)>, 108L<OCSP_sendreq_new(3)> 109 110=head1 COPYRIGHT 111 112Copyright 2015-2024 The OpenSSL Project Authors.
