-=head1 NAME
-
-openssl-ciphers,
-ciphers - SSL cipher display and cipher list tool.
-
-=head1 SYNOPSIS
-
-B<openssl> B<ciphers>
-[B<-v>]
-[B<-V>]
-[B<-ssl2>]
-[B<-ssl3>]
-[B<-tls1>]
-[B<cipherlist>]
-
-=head1 DESCRIPTION
-
-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.
-
-=head1 COMMAND OPTIONS
-
-=over 4
-
-=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.
-
-=item B<-V>
-
-Like B<-v>, but include cipher suite codes in output (hex format).
-
-=item B<-ssl3>, B<-tls1>
-
-This lists ciphers compatible with any of SSLv3, TLSv1, TLSv1.1 or TLSv1.2.
-
-=item B<-ssl2>
-
-Only include SSLv2 ciphers.
-
-=item B<-h>, B<-?>
-
-Print a brief usage message.
-
-=item B<cipherlist>
-
-A cipher list to convert to a cipher preference list. If it is not included
-then the default cipher list will be used. The format is described below.
-
-=back
-
-=head1 CIPHER LIST FORMAT
-
-The cipher list consists of one or more I<cipher strings> separated by colons.
-Commas or spaces are also acceptable separators but colons are normally used.
-
-The actual cipher string can take several different forms.
-
-It can consist of a single cipher suite such as B<RC4-SHA>.
-
-It can represent a list of cipher suites containing a certain algorithm, or
-cipher suites of a certain type. For example B<SHA1> represents all ciphers
-suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3
-algorithms.
-
-Lists of cipher suites can be combined in a single cipher string using the
-B<+> character. This is used as a logical B<and> operation. For example
-B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
-algorithms.
-
-Each cipher string can be optionally preceded by the characters B<!>,
-B<-> or B<+>.
-
-If B<!> is used then the ciphers are permanently deleted from the list.
-The ciphers deleted can never reappear in the list even if they are
-explicitly stated.
-
-If B<-> is used then the ciphers are deleted from the list, but some or
-all of the ciphers can be added again by later options.
-
-If B<+> is used then the ciphers are moved to the end of the list. This
-option doesn't add any new ciphers it just moves matching existing ones.
-
-If none of these characters is present then the string is just interpreted
-as a list of ciphers to be appended to the current preference list. If the
-list includes any ciphers already present they will be ignored: that is they
-will not moved to the end of the list.
-
-Additionally the cipher string B<@STRENGTH> can be used at any point to sort
-the current cipher list in order of encryption algorithm key length.
-
-=head1 CIPHER STRINGS
-
-The following is a list of all permitted cipher strings and their meanings.
-
-=over 4
-
-=item B<DEFAULT>
-
-The default cipher list.
-This is determined at compile time and is normally
-B<ALL:!EXPORT:!LOW:!aNULL:!eNULL:!SSLv2>.
-When used, this must be the first cipherstring specified.
-
-=item B<COMPLEMENTOFDEFAULT>
-
-the ciphers included in B<ALL>, but not enabled by default. Currently
-this is B<ADH> and B<AECDH>. Note that this rule does not cover B<eNULL>,
-which is not included by B<ALL> (use B<COMPLEMENTOFALL> if necessary).
-
-=item B<ALL>
-
-all cipher suites except the B<eNULL> ciphers which must be explicitly enabled;
-as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default
-
-=item B<COMPLEMENTOFALL>
-
-the cipher suites not enabled by B<ALL>, currently being B<eNULL>.
-
-=item B<HIGH>
-
-"high" encryption cipher suites. This currently means those with key lengths larger
-than 128 bits, and some cipher suites with 128-bit keys.
-
-=item B<MEDIUM>
-
-"medium" encryption cipher suites, currently some of those using 128 bit encryption.
-
-=item B<LOW>
-
-Low strength encryption cipher suites, currently those using 64 or 56 bit
-encryption algorithms but excluding export cipher suites.
-As of OpenSSL 1.0.2g, these are disabled in default builds.
-
-=item B<EXP>, B<EXPORT>
-
-Export strength encryption algorithms. Including 40 and 56 bits algorithms.
-As of OpenSSL 1.0.2g, these are disabled in default builds.
-
-=item B<EXPORT40>
-
-40-bit export encryption algorithms
-As of OpenSSL 1.0.2g, these are disabled in default builds.
-
-=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.
-As of OpenSSL 1.0.2g, these are disabled in default builds.
-
-=item B<eNULL>, B<NULL>
-
-The "NULL" ciphers that is those offering no encryption. Because these offer no
-encryption at all and are a security risk they are not enabled via either the
-B<DEFAULT> or B<ALL> cipher strings.
-Be careful when building cipherlists out of lower-level primitives such as
-B<kRSA> or B<aECDSA> as these do overlap with the B<eNULL> ciphers.
-When in doubt, include B<!eNULL> in your cipherlist.
-
-=item B<aNULL>
-
-The cipher suites offering no authentication. This is currently the anonymous
-DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable
-to a "man in the middle" attack and so their use is normally discouraged.
-These are excluded from the B<DEFAULT> ciphers, but included in the B<ALL>
-ciphers.
-Be careful when building cipherlists out of lower-level primitives such as
-B<kDHE> or B<AES> as these do overlap with the B<aNULL> ciphers.
-When in doubt, include B<!aNULL> in your cipherlist.

-=head1 NOTES
-
-Some compiled versions of OpenSSL may not include all the ciphers
-listed here because some ciphers were excluded at compile time.
-
-=head1 EXAMPLES
-
-Verbose listing of all OpenSSL ciphers including NULL ciphers:
-
- openssl ciphers -v 'ALL:eNULL'
-
-Include all ciphers except NULL and anonymous DH then sort by
-strength:
-
- 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 chiphers with RSA authentication but leave out ciphers without
-encryption.
-
- openssl ciphers -v 'RSA:!COMPLEMENTOFALL'

-=head1 HISTORY
-
-The B<COMPLENTOFALL> and B<COMPLEMENTOFDEFAULT> selection options
-for cipherlist strings were added in OpenSSL 0.9.7.
-The B<-V> option for the B<ciphers> command was added in OpenSSL 1.0.0.
