22 | =head1 DESCRIPTION | |
23 | ||
13e4670c | 24 | The B<ciphers> command converts textual OpenSSL cipher lists into ordered |
64287002 DSH |
25 | SSL cipher preference lists. It can be used as a test tool to determine |
26 | the appropriate cipherlist. | |

34 | Only list supported ciphers: those consistent with the security level. This | |
35 | is the actual cipher list an application will support. If this option is | |
36 | not used then ciphers excluded by the security level will still be listed. | |

85 | =head1 CIPHER LIST FORMAT |
86 | ||
87 | The cipher list consists of one or more I<cipher strings> separated by colons. | |
88 | Commas or spaces are also acceptable separators but colons are normally used. | |
89 | ||
90 | The actual cipher string can take several different forms. | |
91 | ||
92 | It can consist of a single cipher suite such as B<RC4-SHA>. | |
93 | ||
94 | It can represent a list of cipher suites containing a certain algorithm, or | |
95 | cipher suites of a certain type. For example B<SHA1> represents all ciphers | |
96 | suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3 | |
97 | algorithms. | |
98 | ||
99 | Lists of cipher suites can be combined in a single cipher string using the | |
100 | B<+> character. This is used as a logical B<and> operation. For example | |
101 | B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES | |
102 | algorithms. | |
103 | ||
104 | Each cipher string can be optionally preceded by the characters B<!>, | |
105 | B<-> or B<+>. | |
106 | ||
107 | If B<!> is used then the ciphers are permanently deleted from the list. | |
108 | The ciphers deleted can never reappear in the list even if they are | |
109 | explicitly stated. | |
110 | ||
111 | If B<-> is used then the ciphers are deleted from the list, but some or | |
112 | all of the ciphers can be added again by later options. | |
113 | ||
114 | If B<+> is used then the ciphers are moved to the end of the list. This | |
115 | option doesn't add any new ciphers it just moves matching existing ones. | |
116 | ||
117 | If none of these characters is present then the string is just interpreted | |
118 | as a list of ciphers to be appended to the current preference list. If the | |
119 | list includes any ciphers already present they will be ignored: that is they | |
120 | will not moved to the end of the list. | |
121 | ||
0f817d3b DSH |
122 | The cipher string B<@STRENGTH> can be used at any point to sort the current |
123 | cipher list in order of encryption algorithm key length. | |
124 | ||
125 | The cipher string B<@SECLEVEL=n> can be used at any point to set the security | |
126 | level to B<n>. | |
64287002 DSH |

128 | =head1 CIPHER STRINGS | |
129 | ||
130 | The following is a list of all permitted cipher strings and their meanings. | |
131 | ||
132 | =over 4 | |
133 | ||
134 | =item B<DEFAULT> | |
135 | ||
c84f7f4a MC |
136 | the default cipher list. This is determined at compile time and |
137 | is B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>. This must be the first cipher | |
138 | string specified. | |
64287002 | 139 | |
c6ccf055 LJ |
140 | =item B<COMPLEMENTOFDEFAULT> |
141 | ||
8be4e173 | 142 | the ciphers included in B<ALL>, but not enabled by default. Currently |
c84f7f4a MC |
143 | this includes all RC4, DES, RC2 and anonymous ciphers. Note that this rule does |
144 | not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if | |
145 | necessary). | |
c6ccf055 | 146 | |
64287002 DSH |
147 | =item B<ALL> |
148 | ||
96afc1cf BM |
149 | all cipher suites except the B<eNULL> ciphers which must be explicitly enabled; |
150 | as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default | |
64287002 | 151 | |
c6ccf055 LJ |
152 | =item B<COMPLEMENTOFALL> |
153 | ||
154 | the cipher suites not enabled by B<ALL>, currently being B<eNULL>. | |
155 | ||
64287002 DSH |
156 | =item B<HIGH> |
157 | ||
ffa45796 DSH |
158 | "high" encryption cipher suites. This currently means those with key lengths |
159 | larger than 128 bits, and some cipher suites with 128-bit keys. | |
64287002 DSH |
160 | |
161 | =item B<MEDIUM> | |
162 | ||
ffa45796 DSH |
163 | "medium" encryption cipher suites, currently some of those using 128 bit |
164 | encryption. | |
64287002 DSH |
165 | |
166 | =item B<LOW> | |
167 | ||
1c735804 VD |
168 | "low" encryption cipher suites, currently those using 64 or 56 bit |
169 | encryption algorithms but excluding export cipher suites. All these | |
170 | ciphersuites have been removed as of OpenSSL 1.1.0. | |
64287002 | 171 | |
64287002 DSH |
172 | =item B<eNULL>, B<NULL> |
173 | ||
174 | the "NULL" ciphers that is those offering no encryption. Because these offer no | |
175 | encryption at all and are a security risk they are disabled unless explicitly | |
176 | included. | |
177 | ||
178 | =item B<aNULL> | |
179 | ||
180 | the cipher suites offering no authentication. This is currently the anonymous | |
343e5cf1 HK |
181 | DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable |
182 | to a "man in the middle" attack and so their use is normally discouraged. | |

254 | ||
255 | Lists ciphersuites which are only supported in at least TLS v1.2, TLS v1.0 | |
256 | or SSL v3.0 respectively. Note: there are no ciphersuites specific to TLS v1.1. | |
257 | Since this is only the minimum version if, for example, TLS v1.0 is supported | |
258 | then both TLS v1.0 and SSL v3.0 ciphersuites are included. | |
