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. - -=item B<kRSA>, B<RSA> - -cipher suites using RSA key exchange or authentication.

-=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 SEE ALSO -
