1=pod 2 3=head1 NAME 4 5OCSP_cert_to_id, OCSP_cert_id_new, OCSP_CERTID_free, OCSP_id_issuer_cmp, 6OCSP_id_cmp, OCSP_id_get0_info - OCSP certificate ID utility functions 7 8=head1 SYNOPSIS 9 10 #include <openssl/ocsp.h> 11 12 OCSP_CERTID *OCSP_cert_to_id(const EVP_MD *dgst, 13 X509 *subject, X509 *issuer); 14 15 OCSP_CERTID *OCSP_cert_id_new(const EVP_MD *dgst, 16 X509_NAME *issuerName, 17 ASN1_BIT_STRING *issuerKey, 18 ASN1_INTEGER *serialNumber); 19 20 void OCSP_CERTID_free(OCSP_CERTID *id); 21 22 int OCSP_id_issuer_cmp(const OCSP_CERTID *a, const OCSP_CERTID *b); 23 int OCSP_id_cmp(const OCSP_CERTID *a, const OCSP_CERTID *b); 24 25 int OCSP_id_get0_info(ASN1_OCTET_STRING **piNameHash, ASN1_OBJECT **pmd, 26 ASN1_OCTET_STRING **pikeyHash, 27 ASN1_INTEGER **pserial, OCSP_CERTID *cid); 28 29 30=head1 DESCRIPTION 31 32OCSP_cert_to_id() creates and returns a new B<OCSP_CERTID> structure using 33message digest B<dgst> for certificate B<subject> with issuer B<issuer>. If 34B<dgst> is B<NULL> then SHA1 is used. 35 36OCSP_cert_id_new() creates and returns a new B<OCSP_CERTID> using B<dgst> and 37issuer name B<issuerName>, issuer key hash B<issuerKey> and serial number 38B<serialNumber>. 39 40OCSP_CERTID_free() frees up B<id>. 41If the argument is NULL, nothing is done. 42 43OCSP_id_cmp() compares B<OCSP_CERTID> B<a> and B<b>. 44 45OCSP_id_issuer_cmp() compares only the issuer name of B<OCSP_CERTID> B<a> and B<b>. 46 47OCSP_id_get0_info() returns the issuer name hash, hash OID, issuer key hash and 48serial number contained in B<cid>. If any of the values are not required the 49corresponding parameter can be set to B<NULL>. 50 51=head1 RETURN VALUES 52 53OCSP_cert_to_id() and OCSP_cert_id_new() return either a pointer to a valid 54B<OCSP_CERTID> structure or B<NULL> if an error occurred. 55 56OCSP_id_cmp() and OCSP_id_issuer_cmp() returns zero for a match and nonzero 57otherwise. 58 59OCSP_CERTID_free() does not return a value. 60 61OCSP_id_get0_info() returns 1 for success and 0 for failure. 62 63=head1 NOTES 64 65OCSP clients will typically only use OCSP_cert_to_id() or OCSP_cert_id_new(): 66the other functions are used by responder applications. 67 68The values returned by OCSP_id_get0_info() are internal pointers and B<MUST 69NOT> be freed up by an application: they will be freed when the corresponding 70B<OCSP_CERTID> structure is freed. 71 72=head1 SEE ALSO 73 74L<crypto(7)>, 75L<OCSP_request_add1_nonce(3)>, 76L<OCSP_REQUEST_new(3)>, 77L<OCSP_resp_find_status(3)>, 78L<OCSP_response_status(3)>, 79L<OCSP_sendreq_new(3)> 80 81=head1 COPYRIGHT 82 83Copyright 2015-2024 The OpenSSL Project Authors.
