184The Online Certificate Status Protocol (\s-1OCSP\s0) enables applications to
185determine the (revocation) state of an identified certificate (\s-1RFC\s0 2560).
984263bc 186.PP
8b0cefbb 187The \fBocsp\fR command performs many common \s-1OCSP\s0 tasks. It can be used
984263bc 188to print out requests and responses, create requests and send queries
8b0cefbb 189to an \s-1OCSP\s0 responder and behave like a mini \s-1OCSP\s0 server itself.

197This specifies the current issuer certificate. This option can be used
198multiple times. The certificate specified in \fBfilename\fR must be in

984263bc 207Same as the \fBcert\fR option except the certificate with serial number

223Add an \s-1OCSP\s0 nonce extension to a request or disable \s-1OCSP\s0 nonce addition.
224Normally if an \s-1OCSP\s0 request is input using the \fBrespin\fR option no
225nonce is added: using the \fBnonce\fR option will force addition of a nonce.
226If an \s-1OCSP\s0 request is being created (using \fBcert\fR and \fBserial\fR options)
227a nonce is automatically added specifying \fBno_nonce\fR overrides this.

259the certificates specified by the \fB\-verify_certs\fR option should be explicitly
260trusted and no additional checks will be performed on them. This is useful
261when the complete responder certificate chain is not available or trusting a

269don't attempt to verify the \s-1OCSP\s0 response signature or the nonce values. This

984263bc
MD
298these options specify the range of times, in seconds, which will be tolerated
299in an \s-1OCSP\s0 response. Each certificate status response includes a \fBnotBefore\fR time and
300an optional \fBnotAfter\fR time. The current time should fall between these two values, but
301the interval between the two times may be only a few seconds. In practice the \s-1OCSP\s0
302responder and clients clocks may not be precisely synchronised and so such a check
303may fail. To avoid this the \fB\-validity_period\fR option can be used to specify an
304acceptable error range in seconds, the default value is 5 minutes.
305.Sp
306If the \fBnotAfter\fR time is omitted from a response then this means that new status
307information is immediately available. In this case the age of the \fBnotBefore\fR field
308is checked to see it is not older than \fBage\fR seconds old. By default this additional
309check is not performed.

359Initially the \s-1OCSP\s0 responder certificate is located and the signature on

364certificates used to build the chain can be specified by the \fBCAfile\fR

371Otherwise the issuing \s-1CA\s0 certificate in the request is compared to the \s-1OCSP\s0

374Otherwise the \s-1OCSP\s0 responder certificate's \s-1CA\s0 is checked against the issuing
375\&\s-1CA\s0 certificate in the request. If there is a match and the OCSPSigning
376extended key usage is present in the \s-1OCSP\s0 responder certificate then the
377\&\s-1OCSP\s0 verify succeeds.

379Otherwise the root \s-1CA\s0 of the \s-1OCSP\s0 responders \s-1CA\s0 is checked to see if it
380is trusted for \s-1OCSP\s0 signing. If it is the \s-1OCSP\s0 verify succeeds.

384What this effectively means if that if the \s-1OCSP\s0 responder certificate is
385authorised directly by the \s-1CA\s0 it is issuing revocation information about
984263bc

386(and it is correctly configured) then verification will succeed.
387.PP
8b0cefbb 388If the \s-1OCSP\s0 responder is a \*(L"global responder\*(R" which can give details about
984263bc 389multiple CAs and has its own separate certificate chain then its root
8b0cefbb 390\&\s-1CA\s0 can be trusted for \s-1OCSP\s0 signing. For example:

401Normally only the \fB\-CApath\fR, \fB\-CAfile\fR and (if the responder is a 'global

404The \s-1OCSP\s0 server is only useful for test and demonstration purposes: it is
405not really usable as a full \s-1OCSP\s0 responder. It contains only a very
406simple \s-1HTTP\s0 request handling and can only handle the \s-1POST\s0 form of \s-1OCSP\s0
984263bc
MD
407queries. It also handles requests serially meaning it cannot respond to
408new requests until it has processed the current one. The text index file
409format of revocation is also inefficient for large quantities of revocation
410data.
411.PP
8b0cefbb 412It is possible to run the \fBocsp\fR application in responder mode via a \s-1CGI\s0
