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
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);
DESCRIPTION
OCSP_cert_to_id(3) creates and returns a new OCSP_CERTID structure using
message digest dgst for certificate subject with issuer issuer. If dgst
is NULL then SHA1 is used.
OCSP_cert_id_new() creates and returns a new OCSP_CERTID using dgst and
issuer name issuerName, issuer key hash issuerKey and serial number
serialNumber.
OCSP_CERTID_free() frees up id. If the argument is NULL, nothing is
done.
OCSP_id_cmp() compares OCSP_CERTID a and b.
OCSP_id_issuer_cmp() compares only the issuer name of OCSP_CERTID a and
b.
OCSP_id_get0_info() returns the issuer name hash, hash OID, issuer key
hash and serial number contained in cid. If any of the values are not
required the corresponding parameter can be set to NULL.
RETURN VALUES
OCSP_cert_to_id(3) and OCSP_cert_id_new() return either a pointer to a
valid OCSP_CERTID structure or 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.
NOTES
OCSP clients will typically only use OCSP_cert_to_id(3) 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
MUST NOT be freed up by an application: they will be freed when the
corresponding OCSP_CERTID structure is freed.
