19 | =head1 DESCRIPTION | |
20 | ||
13e4670c | 21 | The B<ciphers> command converts textual OpenSSL cipher lists into ordered |
64287002 DSH |
22 | SSL cipher preference lists. It can be used as a test tool to determine |
23 | the appropriate cipherlist. | |
24 | ||
25 | =head1 COMMAND OPTIONS | |
26 | ||
27 | =over 4 | |
28 | ||
0f817d3b DSH |
29 | =item B<-s> |
30 | ||
31 | Only list supported ciphers: those consistent with the security level. This | |
32 | is the actual cipher list an application will support. If this option is | |
33 | not used then ciphers excluded by the security level will still be listed. | |
34 | ||
64287002 DSH |
35 | =item B<-v> |
36 | ||
13e4670c | 37 | Verbose option. List ciphers with a complete description of |
8acdd759 BM |
38 | protocol version (SSLv2 or SSLv3; the latter includes TLS), key exchange, |
39 | authentication, encryption and mac algorithms used along with any key size | |
64287002 | 40 | restrictions and whether the algorithm is classed as an "export" cipher. |
8acdd759 BM |
41 | Note that without the B<-v> option, ciphers may seem to appear twice |
42 | in a cipher list; this is when similar ciphers are available for | |
43 | SSL v2 and for SSL v3/TLS v1. | |
64287002 | 44 | |

71 | ||
72 | a cipher list to convert to a cipher preference list. If it is not included | |
73 | then the default cipher list will be used. The format is described below. | |

77 | =head1 CIPHER LIST FORMAT |
78 | ||
79 | The cipher list consists of one or more I<cipher strings> separated by colons. | |
80 | Commas or spaces are also acceptable separators but colons are normally used. | |
81 | ||
82 | The actual cipher string can take several different forms. | |
83 | ||
84 | It can consist of a single cipher suite such as B<RC4-SHA>. | |
85 | ||
86 | It can represent a list of cipher suites containing a certain algorithm, or | |
87 | cipher suites of a certain type. For example B<SHA1> represents all ciphers | |
88 | suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3 | |
89 | algorithms. | |
90 | ||
91 | Lists of cipher suites can be combined in a single cipher string using the | |
92 | B<+> character. This is used as a logical B<and> operation. For example | |
93 | B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES | |
94 | algorithms. | |
95 | ||
96 | Each cipher string can be optionally preceded by the characters B<!>, | |
97 | B<-> or B<+>. | |
98 | ||
99 | If B<!> is used then the ciphers are permanently deleted from the list. | |
100 | The ciphers deleted can never reappear in the list even if they are | |
101 | explicitly stated. | |
102 | ||
103 | If B<-> is used then the ciphers are deleted from the list, but some or | |
104 | all of the ciphers can be added again by later options. | |
105 | ||
106 | If B<+> is used then the ciphers are moved to the end of the list. This | |
107 | option doesn't add any new ciphers it just moves matching existing ones. | |
108 | ||
109 | If none of these characters is present then the string is just interpreted | |
110 | as a list of ciphers to be appended to the current preference list. If the | |
111 | list includes any ciphers already present they will be ignored: that is they | |
112 | will not moved to the end of the list. | |
113 | ||
0f817d3b DSH |
114 | The cipher string B<@STRENGTH> can be used at any point to sort the current |
115 | cipher list in order of encryption algorithm key length. | |
116 | ||
117 | The cipher string B<@SECLEVEL=n> can be used at any point to set the security | |
118 | level to B<n>. | |

124 | =over 4 | |
125 | ||
126 | =item B<DEFAULT> | |
127 | ||
96afc1cf | 128 | the default cipher list. This is determined at compile time and, as of OpenSSL |
fb552ac6 | 129 | 1.0.0, is normally B<ALL:!aNULL:!eNULL>. This must be the first cipher string |
3142c86d | 130 | specified. |
64287002 | 131 | |
c6ccf055 LJ |
132 | =item B<COMPLEMENTOFDEFAULT> |
133 | ||
8be4e173 | 134 | the ciphers included in B<ALL>, but not enabled by default. Currently |
343e5cf1 HK |
135 | this is B<ADH> and B<AECDH>. Note that this rule does not cover B<eNULL>, |
136 | which is not included by B<ALL> (use B<COMPLEMENTOFALL> if necessary). | |
c6ccf055 | 137 | |
64287002 DSH |
138 | =item B<ALL> |
139 | ||
96afc1cf BM |
140 | all cipher suites except the B<eNULL> ciphers which must be explicitly enabled; |
141 | as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default | |
64287002 | 142 | |
c6ccf055 LJ |
143 | =item B<COMPLEMENTOFALL> |

64287002 DSH |
147 | =item B<HIGH> |
148 | ||
ffa45796 DSH |
149 | "high" encryption cipher suites. This currently means those with key lengths |
150 | larger than 128 bits, and some cipher suites with 128-bit keys. | |
64287002 DSH |
151 | |
152 | =item B<MEDIUM> | |
153 | ||
ffa45796 DSH |

155 | encryption. | |

156 | |
157 | =item B<LOW> | |
158 | ||
ffa45796 DSH |
159 | "low" encryption cipher suites, currently those using 64 or 56 bit encryption |
160 | algorithms but excluding export cipher suites. | |

172 | 56 bit export encryption algorithms. In OpenSSL 0.9.8c and later the set of |
173 | 56 bit export ciphers is empty unless OpenSSL has been explicitly configured | |
174 | with support for experimental ciphers. | |
64287002 DSH |
175 | |
176 | =item B<eNULL>, B<NULL> | |
177 | ||
178 | the "NULL" ciphers that is those offering no encryption. Because these offer no | |
179 | encryption at all and are a security risk they are disabled unless explicitly | |
180 | included. | |
181 | ||
182 | =item B<aNULL> | |
183 | ||
184 | the cipher suites offering no authentication. This is currently the anonymous | |
343e5cf1 HK |
185 | DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable |
186 | to a "man in the middle" attack and so their use is normally discouraged. | |

353 | consequences required to comply with RFC6460. In particular the supported | |
354 | signature algorithms is reduced to support only ECDSA and SHA256 or SHA384, | |
355 | only the elliptic curves P-256 and P-384 can be used and only the two suite B | |
