.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

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 \s-1OCSP_CERTID\s0 structure using message digest dgst for certificate subject with issuer issuer. If \fBdgst is \s-1NULL\s0 then \s-1SHA1\s0 is used.

\fBOCSP_cert_id_new() creates and returns a new \s-1OCSP_CERTID\s0 using dgst and issuer name issuerName, issuer key hash issuerKey and serial number \fBserialNumber.

\fBOCSP_CERTID_free() frees up id.

\fBOCSP_id_cmp() compares \s-1OCSP_CERTID\s0 a and b.

\fBOCSP_id_issuer_cmp() compares only the issuer name of \s-1OCSP_CERTID\s0 a and b.

\fBOCSP_id_get0_info() returns the issuer name hash, hash \s-1OID,\s0 issuer key hash and serial number contained in cid. If any of the values are not required the corresponding parameter can be set to \s-1NULL\s0.

Header "RETURN VALUES" \fBOCSP_cert_to_id() and OCSP_cert_id_new() return either a pointer to a valid \fB\s-1OCSP_CERTID\s0 structure or \s-1NULL\s0 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" \s-1OCSP\s0 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 \s-1MUST NOT\s0 be freed up by an application: they will be freed when the corresponding \fB\s-1OCSP_CERTID\s0 structure is freed.
