.. \*(C` and \*(C' are quotes in nroff, nothing in troff, for use with C<>.
. ds C` "" . ds C' "" 'br\} . ds C` . ds C' 'br\}
Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "OCSP_cert_to_id 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
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 Header "SYNOPSIS" .Vb 1 #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); .Ve Header "DESCRIPTION" \fBOCSP_cert_to_id() creates and returns a new OCSP_CERTID structure using message digest dgst for certificate subject with issuer issuer. If \fBdgst is NULL then SHA1 is used.

\fBOCSP_cert_id_new() creates and returns a new OCSP_CERTID using dgst and issuer name issuerName, issuer key hash issuerKey and serial number \fBserialNumber.

\fBOCSP_CERTID_free() frees up id. If the argument is NULL, nothing is done.

\fBOCSP_id_cmp() compares OCSP_CERTID a and b.

\fBOCSP_id_issuer_cmp() compares only the issuer name of OCSP_CERTID a and b.

\fBOCSP_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.

Header "RETURN VALUES" \fBOCSP_cert_to_id() and OCSP_cert_id_new() return either a pointer to a valid \fBOCSP_CERTID structure or NULL if an error occurred.

\fBOCSP_id_cmp() and OCSP_id_issuer_cmp() returns zero for a match and nonzero otherwise.

\fBOCSP_CERTID_free() does not return a value.

\fBOCSP_id_get0_info() returns 1 for success and 0 for failure.

Header "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 MUST NOT be freed up by an application: they will be freed when the corresponding \fBOCSP_CERTID structure is freed.
