.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBOCSP_response_status()\fR returns the \s-1OCSP\s0 response status of \fBresp\fR. It returns
one of the values: \fB\s-1OCSP_RESPONSE_STATUS_SUCCESSFUL\s0\fR,
\&\fB\s-1OCSP_RESPONSE_STATUS_MALFORMEDREQUEST\s0\fR,
\&\fB\s-1OCSP_RESPONSE_STATUS_INTERNALERROR\s0\fR, \fB\s-1OCSP_RESPONSE_STATUS_TRYLATER\s0\fR
\&\fB\s-1OCSP_RESPONSE_STATUS_SIGREQUIRED\s0\fR, or \fB\s-1OCSP_RESPONSE_STATUS_UNAUTHORIZED\s0\fR.
.PP
\&\fBOCSP_response_get1_basic()\fR decodes and returns the \fB\s-1OCSP_BASICRESP\s0\fR structure
contained in \fBresp\fR.
.PP
\&\fBOCSP_response_create()\fR creates and returns an \fB\s-1OCSP_RESPONSE\s0\fR structure for
\&\fBstatus\fR and optionally including basic response \fBbs\fR.
.PP
\&\fBOCSP_RESPONSE_free()\fR frees up \s-1OCSP\s0 response \fBresp\fR.
.PP
\&\fBOCSP_RESPID_set_by_name()\fR sets the name of the \s-1OCSP_RESPID\s0 to be the same as the
subject name in the supplied X509 certificate \fBcert\fR for the \s-1OCSP\s0 responder.
.PP
\&\fBOCSP_RESPID_set_by_key()\fR sets the key of the \s-1OCSP_RESPID\s0 to be the same as the
key in the supplied X509 certificate \fBcert\fR for the \s-1OCSP\s0 responder. The key is
stored as a \s-1SHA1\s0 hash.
.PP
Note that an \s-1OCSP_RESPID\s0 can only have one of the name, or the key set. Calling
\&\fBOCSP_RESPID_set_by_name()\fR or \fBOCSP_RESPID_set_by_key()\fR will clear any existing
setting.
.PP
\&\fBOCSP_RESPID_match()\fR tests whether the \s-1OCSP_RESPID\s0 given in \fBrespid\fR matches
with the X509 certificate \fBcert\fR.
.PP
\&\fBOCSP_basic_sign()\fR signs \s-1OCSP\s0 response \fBbrsp\fR using certificate \fBsigner\fR, private key
\&\fBkey\fR, digest \fBdgst\fR and additional certificates \fBcerts\fR. If the \fBflags\fR option
\&\fB\s-1OCSP_NOCERTS\s0\fR is set then no certificates will be included in the response. If the
\&\fBflags\fR option \fB\s-1OCSP_RESPID_KEY\s0\fR is set then the responder is identified by key \s-1ID\s0
rather than by name. \fBOCSP_basic_sign_ctx()\fR also signs \s-1OCSP\s0 response \fBbrsp\fR but
uses the parameters contained in digest context \fBctx\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBOCSP_RESPONSE_status()\fR returns a status value.
.PP
\&\fBOCSP_response_get1_basic()\fR returns an \fB\s-1OCSP_BASICRESP\s0\fR structure pointer or
\&\fB\s-1NULL\s0\fR if an error occurred.
.PP
\&\fBOCSP_response_create()\fR returns an \fB\s-1OCSP_RESPONSE\s0\fR structure pointer or \fB\s-1NULL\s0\fR
if an error occurred.
.PP
\&\fBOCSP_RESPONSE_free()\fR does not return a value.
.PP
\&\fBOCSP_RESPID_set_by_name()\fR, \fBOCSP_RESPID_set_by_key()\fR, \fBOCSP_basic_sign()\fR, and
\&\fBOCSP_basic_sign_ctx()\fR return 1 on success or 0
on failure.
.PP
\&\fBOCSP_RESPID_match()\fR returns 1 if the \s-1OCSP_RESPID\s0 and the X509 certificate match
or 0 otherwise.
.SH "NOTES"
.IX Header "NOTES"
\&\fBOCSP_response_get1_basic()\fR is only called if the status of a response is
\&\fB\s-1OCSP_RESPONSE_STATUS_SUCCESSFUL\s0\fR.
