It returns 34the B<OCSP_ONEREQ> structure added so an application can add additional 35extensions to the request. The B<id> parameter B<MUST NOT> be freed up after 36the operation. 37 38OCSP_request_sign() signs OCSP request B<req> using certificate 39B<signer>, private key B<key>, digest B<dgst> and additional certificates 40B<certs>. If the B<flags> option B<OCSP_NOCERTS> is set then no certificates 41will be included in the request. 42 43OCSP_request_add1_cert() adds certificate B<cert> to request B<req>. The 44application is responsible for freeing up B<cert> after use. 45 46OCSP_request_onereq_count() returns the total number of B<OCSP_ONEREQ> 47structures in B<req>. 48 49OCSP_request_onereq_get0() returns an internal pointer to the B<OCSP_ONEREQ> 50contained in B<req> of index B<i>. The index value B<i> runs from 0 to 51OCSP_request_onereq_count(req) - 1. 52 53=head1 RETURN VALUES 54 55OCSP_REQUEST_new() returns an empty B<OCSP_REQUEST> structure or B<NULL> if 56an error occurred. 57 58OCSP_request_add0_id() returns the B<OCSP_ONEREQ> structure containing B<cid> 59or B<NULL> if an error occurred. 60 61OCSP_request_sign() and OCSP_request_add1_cert() return 1 for success and 0 62for failure. 63 64OCSP_request_onereq_count() returns the total number of B<OCSP_ONEREQ> 65structures in B<req>. 66 67OCSP_request_onereq_get0() returns a pointer to an B<OCSP_ONEREQ> structure 68or B<NULL> if the index value is out or range. 69 70=head1 NOTES 71 72An OCSP request structure contains one or more B<OCSP_ONEREQ> structures 73corresponding to each certificate. 74 75OCSP_request_onereq_count() and OCSP_request_onereq_get0() are mainly used by 76OCSP responders. 77 78=head1 EXAMPLES 79 80Create an B<OCSP_REQUEST> structure for certificate B<cert> with issuer 81B<issuer>: 82 83 OCSP_REQUEST *req; 84 OCSP_ID *cid; 85 86 req = OCSP_REQUEST_new(); 87 if (req == NULL) 88 /* error */ 89 cid = OCSP_cert_to_id(EVP_sha1(), cert, issuer); 90 if (cid == NULL) 91 /* error */ 92 93 if (OCSP_REQUEST_add0_id(req, cid) == NULL) 94 /* error */ 95 96 /* Do something with req, e.g. query responder */ 97 98 OCSP_REQUEST_free(req); 99 100=head1 SEE ALSO 101 102L<crypto(7)>, 103L<OCSP_cert_to_id(3)>, 104L<OCSP_request_add1_nonce(3)>, 105L<OCSP_resp_find_status(3)>, 106L<OCSP_response_status(3)>, 107L<OCSP_sendreq_new(3)> 108 109=head1 COPYRIGHT 110 111Copyright 2015-2019 The OpenSSL Project Authors.
