=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 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<MUST
|
|
NOT> be freed up by an application: they will be freed when the corresponding
|
|
B<OCSP_CERTID> structure is freed.
