=head1 DESCRIPTION
-The B<cipherlist> command converts OpenSSL cipher lists into ordered
+The B<ciphers> command converts textual OpenSSL cipher lists into ordered
SSL cipher preference lists. It can be used as a test tool to determine
the appropriate cipherlist.

+=item B<-help>
+
+Print out a usage message.
+
+=item B<-s>
+
+Only list supported ciphers: those consistent with the security level. This
+is the actual cipher list an application will support. If this option is
+not used then ciphers excluded by the security level will still be listed.
+
+=item B<-psk>
+
+When combined with B<-s> includes cipher suites which require PSK.
+
=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.
+Verbose output: For each ciphersuite, list details as provided by
+L<SSL_CIPHER_description(3)>.

=head1 NOTES
-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.
openssl ciphers -v 'ALL:!ADH:@STRENGTH'
+Include all ciphers except ones with no encryption (eNULL) or no
+authentication (aNULL):
+
+ openssl ciphers -v 'ALL:!aNULL'
+
Include only 3DES ciphers and then place RSA ciphers last:
openssl ciphers -v '3DES:+RSA'
+Include all RC4 ciphers but leave out those without authentication:
+
+ openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
+
+Include all ciphers with RSA authentication but leave out ciphers without
+encryption.
+
+ openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
+
+Set security level to 2 and display all ciphers consistent with level 2:
+
+ openssl ciphers -s -v 'ALL:@SECLEVEL=2'
