=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 <openssl/ocsp.h>
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(const OCSP_CERTID *a, const OCSP_CERTID *b);
int OCSP_id_cmp(const OCSP_CERTID *a, const 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<OCSP_CERTID> structure using
message digest B<dgst> for certificate B<subject> with issuer B<issuer>. If
B<dgst> is B<NULL> then SHA1 is used.
OCSP_cert_id_new() creates and returns a new B<OCSP_CERTID> using B<dgst> and
issuer name B<issuerName>, issuer key hash B<issuerKey> and serial number
B<serialNumber>.
OCSP_CERTID_free() frees up B<id>.
OCSP_id_cmp() compares B<OCSP_CERTID> B<a> and B<b>.
OCSP_id_issuer_cmp() compares only the issuer name of B<OCSP_CERTID> B<a> and B<b>.
OCSP_id_get0_info() returns the issuer name hash, hash OID, issuer key hash and
serial number contained in B<cid>. If any of the values are not required the
corresponding parameter can be set to B<NULL>.
=head1 RETURN VALUES
OCSP_cert_to_id() and OCSP_cert_id_new() return either a pointer to a valid
B<OCSP_CERTID> structure or B<NULL> if an error occurred.
OCSP_id_cmp() and OCSP_id_issuer_cmp() returns zero for a match and nonzero
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<MUST
NOT> be freed up by an application: they will be freed when the corresponding
B<OCSP_CERTID> structure is freed.
