+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, key exchange,
-authentication, encryption and mac algorithms used along with any key size
-restrictions and whether the algorithm is classed as an "export" cipher.
+Verbose output: For each ciphersuite, list details as provided by
+L<SSL_CIPHER_description(3)>.
=item B<-V>
-Like B<-v>, but include cipher suite codes in output (hex format).
+Like B<-v>, but include the official cipher suite values in hex.
=item B<-ssl3>
-only include SSL v3 ciphers.
+List the ciphers which would be used if SSL v3 was negotiated.
=item B<-tls1>
-only include TLS v1 ciphers.
+List the ciphers which would be used if TLS v1.0 was negotiated.
+
+=item B<-tls1_1>
+
+List the ciphers which would be used if TLS v1.1 was negotiated.
+
+=item B<-tls1_2>
+
+List the ciphers which would be used if TLS v1.2 was negotiated.
=item B<-stdname>
=item B<LOW>
-"low" encryption cipher suites, currently those using 64 or 56 bit encryption
-algorithms but excluding export cipher suites.
-
-=item B<EXP>, B<EXPORT>
-
-export encryption algorithms. Including 40 and 56 bits algorithms.
-
-=item B<EXPORT40>
-
-40 bit export encryption algorithms
-
-=item B<EXPORT56>
-
-56 bit export encryption algorithms. In OpenSSL 0.9.8c and later the set of
-56 bit export ciphers is empty unless OpenSSL has been explicitly configured
-with support for experimental ciphers.
+"low" encryption cipher suites, currently those using 64 or 56 bit
+encryption algorithms but excluding export cipher suites. All these
+ciphersuites have been removed as of OpenSSL 1.1.0.
=item B<eNULL>, B<NULL>
cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA
keys.
-=item B<TLSv1.2>, B<TLSv1>, B<SSLv3>
+=item B<TLSv1.2>, B<TLSv1.0>, B<SSLv3>
+
+Lists ciphersuites which are only supported in at least TLS v1.2, TLS v1.0
+or SSL v3.0 respectively. Note: there are no ciphersuites specific to TLS v1.1.
+Since this is only the minimum version if, for example, TLS v1.0 is supported
+then both TLS v1.0 and SSL v3.0 ciphersuites are included.
-TLS v1.2, TLS v1.0 or SSL v3.0 cipher suites respectively. Note:
-there are no ciphersuites specific to TLS v1.1.
+Note: these cipher strings B<do not> change the negotiated version of SSL or
+TLS only the list of cipher suites.

=head1 HISTORY
-The B<COMPLENTOFALL> and B<COMPLEMENTOFDEFAULT> selection options
