=over 4
+=item B<-help>
+
+Print a usage message.
+
+=item B<-s>
+
+Only list supported ciphers: those consistent with the security level, and
+minimum and maximum protocol version. This is closer to the actual cipher list
+an application will support.
+
+PSK and SRP ciphers are not enabled by default: they require B<-psk> or B<-srp>
+to enable them.
+
+It also does not change the default list of supported signature algorithms.
+
+On a server the list of supported ciphers might also exclude other ciphers
+depending on the configured certificates and presence of DH parameters.
+
+If this option is not used then all ciphers that match the cipherlist will be
+listed.
+
+=item B<-psk>
+
+When combined with B<-s> includes cipher suites which require PSK.

+=item B<-srp>
+
+When combined with B<-s> includes cipher suites which require SRP.

=item B<-v>
-Verbose option. List ciphers with a complete description of
-protocol version (SSLv2 or SSLv3; the latter includes TLS), key exchange,
-authentication, encryption and mac algorithms used along with any key size
-restrictions and whether the algorithm is classed as an "export" cipher.
-Note that without the B<-v> option, ciphers may seem to appear twice
-in a cipher list; this is when similar ciphers are available for
-SSL v2 and for SSL v3/TLS v1.

-The non-ephemeral DH modes are currently unimplemented in OpenSSL
-because there is no support for DH certificates.
-
Some compiled versions of OpenSSL may not include all the ciphers
listed here because some ciphers were excluded at compile time.
