| =head1 NAME |
| |
| 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> |
| |
| only include SSL v3 ciphers. |
| |
| =item B<-ssl2> |
| |
| only include SSL v2 ciphers. |
| |
| =item B<-tls1> |
| |
| only include TLS v1 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:!aNULL:!eNULL:!SSLv2>. This must be the firstcipher string |
| 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" 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. |
| |
| =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 disabled unless explicitly |
| included. |
| |
| =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. |

| |
| cipher suites using RSA key exchange. |
| |
| =item B<kDHr>, B<kDHd>, B<kDH> |

| suites. |

| =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. |
| |
| =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. |
