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>. 41 42OCSP_id_cmp() compares B<OCSP_CERTID> B<a> and B<b>. 43 44OCSP_id_issuer_cmp() compares only the issuer name of B<OCSP_CERTID> B<a> and B<b>. 45 46OCSP_id_get0_info() returns the issuer name hash, hash OID, issuer key hash and 47serial number contained in B<cid>. If any of the values are not required the 48corresponding parameter can be set to B<NULL>. 49 50=head1 RETURN VALUES 51 52OCSP_cert_to_id() and OCSP_cert_id_new() return either a pointer to a valid 53B<OCSP_CERTID> structure or B<NULL> if an error occurred. 54 55OCSP_id_cmp() and OCSP_id_issuer_cmp() returns zero for a match and non-zero 56otherwise. 57 58OCSP_CERTID_free() does not return a value. 59 60OCSP_id_get0_info() returns 1 for success and 0 for failure. 61 62=head1 NOTES 63 64OCSP clients will typically only use OCSP_cert_to_id() or OCSP_cert_id_new(): 65the other functions are used by responder applications. 66 67The values returned by OCSP_id_get0_info() are internal pointers and B<MUST 68NOT> be freed up by an application: they will be freed when the corresponding 69B<OCSP_CERTID> structure is freed. 70 71=head1 SEE ALSO 72 73L<crypto(7)>, 74L<OCSP_request_add1_nonce(3)>, 75L<OCSP_REQUEST_new(3)>, 76L<OCSP_resp_find_status(3)>, 77L<OCSP_response_status(3)>, 78L<OCSP_sendreq_new(3)> 79 80=head1 COPYRIGHT 81 82Copyright 2015-2019 The OpenSSL Project Authors.
