+=item B<-index indexfile>
+
+B<indexfile> is a text index file in B<ca> format containing certificate revocation
+information.
+
+If the B<index> option is specified the B<ocsp> utility is in responder mode, otherwise
+it is in client mode. The request(s) the responder processes can be either specified on
+the command line (using B<issuer> and B<serial> options), supplied in a file (using the
+B<respin> option) or via external OCSP clients (if B<port> or B<url> is specified).
+
+If the B<index> option is present then the B<CA> and B<rsigner> options must also be
+present.
+
+=item B<-CA file>
+
+CA certificate corresponding to the revocation information in B<indexfile>.

+
+Additional certificates to include in the OCSP response.

+=item B<-resp_no_certs>
+
+Don't include any certificates in the OCSP response.

+=item B<-resp_key_id>
+
+Identify the signer certificate using the key ID, default is to use the subject name.
+
+=item B<-rkey file>
+
+The private key to sign OCSP responses with: if not present the file specified in the
+B<rsigner> option is used.
+
+=item B<-port portnum>
+
+Port to listen for OCSP requests on. The port may also be specified using the B<url>
+option.
+
+=item B<-nrequest number>
+
+The OCSP server will exit after receiving B<number> requests, default unlimited.
+
+=item B<-nmin minutes>, B<-ndays days>
+
+Number of minutes or days when fresh revocation information is available: used in the

=head1 OCSP Response verification.
OCSP Response follows the rules specified in RFC2560.
Normally only the B<-CApath>, B<-CAfile> and (if the responder is a 'global
VA') B<-VAfile> options need to be used.
+The OCSP server is only useful for test and demonstration purposes: it is
+not really usable as a full OCSP responder. It contains only a very
+simple HTTP request handling and can only handle the POST form of OCSP
+queries. It also handles requests serially meaning it cannot respond to
+new requests until it has processed the current one. The text index file
+format of revocation is also inefficient for large quantities of revocation
+data.
+
+It is possible to run the B<ocsp> application in responder mode via a CGI
+script using the B<respin> and B<respout> options.

+OCSP server on port 8888 using a standard B<ca> configuration, and a separate

+
+ openssl ocsp -index demoCA/index.txt -port 8888 -rsigner rcert.pem -CA demoCA/cacert.pem

+
+As above but exit after processing one request:
