=pod =head1 NAME OCSP_cert_to_id, OCSP_cert_id_new, OCSP_CERTID_free, OCSP_id_issuer_cmp, OCSP_id_cmp, OCSP_id_get0_info - OCSP certificate ID utility functions =head1 SYNOPSIS #include OCSP_CERTID *OCSP_cert_to_id(const EVP_MD *dgst, X509 *subject, X509 *issuer); OCSP_CERTID *OCSP_cert_id_new(const EVP_MD *dgst, X509_NAME *issuerName, ASN1_BIT_STRING *issuerKey, ASN1_INTEGER *serialNumber); void OCSP_CERTID_free(OCSP_CERTID *id); int OCSP_id_issuer_cmp(OCSP_CERTID *a, OCSP_CERTID *b); int OCSP_id_cmp(OCSP_CERTID *a, OCSP_CERTID *b); int OCSP_id_get0_info(ASN1_OCTET_STRING **piNameHash, ASN1_OBJECT **pmd, ASN1_OCTET_STRING **pikeyHash, ASN1_INTEGER **pserial, OCSP_CERTID *cid); =head1 DESCRIPTION OCSP_cert_to_id() creates and returns a new B structure using message digest B for certificate B with issuer B. If B is B then SHA1 is used. OCSP_cert_id_new() creates and returns a new B using B and issuer name B, issuer key hash B and serial number B. OCSP_CERTID_free() frees up B. OCSP_id_cmp() compares B B and B. OCSP_id_issuer_cmp() compares only the issuer name of B B and B. OCSP_id_get0_info() returns the issuer name hash, hash OID, issuer key hash and serial number contained in B. If any of the values are not required the corresponding parameter can be set to B. =head1 RETURN VALUES OCSP_cert_to_id() and OCSP_cert_id_new() return either a pointer to a valid B structure or B if an error occurred. OCSP_id_cmp() and OCSP_id_issuer_cmp() returns zero for a match and non-zero otherwise. OCSP_CERTID_free() does not return a value. OCSP_id_get0_info() returns 1 for success and 0 for failure. =head1 NOTES OCSP clients will typically only use OCSP_cert_to_id() or OCSP_cert_id_new(): the other functions are used by responder applications. The values returned by OCSP_id_get0_info() are internal pointers and B be freed up by an application: they will be freed when the corresponding B structure is freed. =head1 SEE ALSO L, L, L, L, L, L =head1 COPYRIGHT Copyright 2015-2016 The OpenSSL Project Authors.
