4 | ||
5 | ciphers - SSL cipher display and cipher list tool. | |
6 | ||
7 | =head1 SYNOPSIS | |
8 | ||
9 | B<openssl> B<ciphers> | |
10 | [B<-v>] | |
13e4670c | 11 | [B<-V>] |
64287002 DSH |

13 | [B<-ssl3>] | |
14 | [B<-tls1>] | |
15 | [B<cipherlist>] | |
16 | ||
17 | =head1 DESCRIPTION | |
18 | ||
13e4670c | 19 | The B<ciphers> command converts textual OpenSSL cipher lists into ordered |
64287002 DSH |
20 | SSL cipher preference lists. It can be used as a test tool to determine |
21 | the appropriate cipherlist. | |
22 | ||
23 | =head1 COMMAND OPTIONS | |
24 | ||
25 | =over 4 | |
26 | ||
27 | =item B<-v> | |
28 | ||
13e4670c | 29 | Verbose option. List ciphers with a complete description of |
8acdd759 BM |
30 | protocol version (SSLv2 or SSLv3; the latter includes TLS), key exchange, |
31 | authentication, encryption and mac algorithms used along with any key size | |
64287002 | 32 | restrictions and whether the algorithm is classed as an "export" cipher. |
8acdd759 BM |
33 | Note that without the B<-v> option, ciphers may seem to appear twice |
34 | in a cipher list; this is when similar ciphers are available for | |
35 | SSL v2 and for SSL v3/TLS v1. | |
64287002 | 36 | |
13e4670c BM |
37 | =item B<-V> |

64287002 | 42 | |
021fb42d | 43 | This lists ciphers compatible with any of SSLv3, TLSv1, TLSv1.1 or TLSv1.2. |
64287002 DSH |

64287002 DSH |
52 | |
53 | =item B<cipherlist> | |
54 | ||
021fb42d | 55 | A cipher list to convert to a cipher preference list. If it is not included |
64287002 DSH |
56 | then the default cipher list will be used. The format is described below. |

60 | =head1 CIPHER LIST FORMAT |
61 | ||
62 | The cipher list consists of one or more I<cipher strings> separated by colons. | |
63 | Commas or spaces are also acceptable separators but colons are normally used. | |
64 | ||
65 | The actual cipher string can take several different forms. | |
66 | ||
67 | It can consist of a single cipher suite such as B<RC4-SHA>. | |
68 | ||
69 | It can represent a list of cipher suites containing a certain algorithm, or | |
70 | cipher suites of a certain type. For example B<SHA1> represents all ciphers | |
71 | suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3 | |
72 | algorithms. | |
73 | ||
74 | Lists of cipher suites can be combined in a single cipher string using the | |
75 | B<+> character. This is used as a logical B<and> operation. For example | |
76 | B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES | |
77 | algorithms. | |
78 | ||
79 | Each cipher string can be optionally preceded by the characters B<!>, | |
80 | B<-> or B<+>. | |
81 | ||
82 | If B<!> is used then the ciphers are permanently deleted from the list. | |
83 | The ciphers deleted can never reappear in the list even if they are | |
84 | explicitly stated. | |
85 | ||
86 | If B<-> is used then the ciphers are deleted from the list, but some or | |
87 | all of the ciphers can be added again by later options. | |
88 | ||
89 | If B<+> is used then the ciphers are moved to the end of the list. This | |
90 | option doesn't add any new ciphers it just moves matching existing ones. | |
91 | ||
92 | If none of these characters is present then the string is just interpreted | |
93 | as a list of ciphers to be appended to the current preference list. If the | |
94 | list includes any ciphers already present they will be ignored: that is they | |
95 | will not moved to the end of the list. | |
96 | ||
97 | Additionally the cipher string B<@STRENGTH> can be used at any point to sort | |
98 | the current cipher list in order of encryption algorithm key length. | |
99 | ||
100 | =head1 CIPHER STRINGS | |
101 | ||
102 | The following is a list of all permitted cipher strings and their meanings. | |
103 | ||
104 | =over 4 | |
105 | ||
106 | =item B<DEFAULT> | |
107 | ||
021fb42d VD |
108 | The default cipher list. |
109 | This is determined at compile time and is normally | |
110 | B<ALL:!EXPORT:!aNULL:!eNULL:!SSLv2>. | |
111 | When used, this must be the first cipherstring specified. | |
64287002 | 112 | |

113 | =item B<COMPLEMENTOFDEFAULT> |
114 | ||
8be4e173 | 115 | the ciphers included in B<ALL>, but not enabled by default. Currently |
4ceddeea HK |
116 | this is B<ADH> and B<AECDH>. Note that this rule does not cover B<eNULL>, |
117 | which is not included by B<ALL> (use B<COMPLEMENTOFALL> if necessary). | |
c6ccf055 | 118 | |
64287002 DSH |
119 | =item B<ALL> |
120 | ||
96afc1cf BM |
121 | all cipher suites except the B<eNULL> ciphers which must be explicitly enabled; |
122 | as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default | |
64287002 | 123 | |
c6ccf055 LJ |
124 | =item B<COMPLEMENTOFALL> |
125 | ||
126 | the cipher suites not enabled by B<ALL>, currently being B<eNULL>. | |
127 | ||
64287002 DSH |
128 | =item B<HIGH> |
129 | ||
130 | "high" encryption cipher suites. This currently means those with key lengths larger | |
75d61b33 | 131 | than 128 bits, and some cipher suites with 128-bit keys. |
64287002 DSH |
132 | |
133 | =item B<MEDIUM> | |
134 | ||
75d61b33 | 135 | "medium" encryption cipher suites, currently some of those using 128 bit encryption. |
64287002 DSH |
136 | |
137 | =item B<LOW> | |
138 | ||
bc38a7d2 VD |
139 | Low strength encryption cipher suites, currently those using 64 or 56 bit |
140 | encryption algorithms but excluding export cipher suites. | |
141 | As of OpenSSL 1.0.2g, these are disabled in default builds. | |
64287002 DSH |
142 | |
143 | =item B<EXP>, B<EXPORT> | |

bc38a7d2 VD |
145 | Export strength encryption algorithms. Including 40 and 56 bits algorithms. |
146 | As of OpenSSL 1.0.2g, these are disabled in default builds. | |
64287002 DSH |
147 | |
148 | =item B<EXPORT40> | |

152 | |
153 | =item B<EXPORT56> | |
154 | ||
bc38a7d2 | 155 | 56-bit export encryption algorithms. In OpenSSL 0.9.8c and later the set of |
bcb38217 NL |
156 | 56 bit export ciphers is empty unless OpenSSL has been explicitly configured |
157 | with support for experimental ciphers. | |
bc38a7d2 | 158 | As of OpenSSL 1.0.2g, these are disabled in default builds. |
64287002 DSH |
159 | |
160 | =item B<eNULL>, B<NULL> | |
161 | ||
bc38a7d2 VD |
162 | The "NULL" ciphers that is those offering no encryption. Because these offer no |
163 | encryption at all and are a security risk they are not enabled via either the | |
164 | B<DEFAULT> or B<ALL> cipher strings. | |
165 | Be careful when building cipherlists out of lower-level primitives such as | |
166 | B<kRSA> or B<aECDSA> as these do overlap with the B<eNULL> ciphers. | |
167 | When in doubt, include B<!eNULL> in your cipherlist. | |
64287002 DSH |
168 | |
169 | =item B<aNULL> | |
170 | ||
bc38a7d2 | 171 | The cipher suites offering no authentication. This is currently the anonymous |
4ceddeea HK |
172 | DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable |
173 | to a "man in the middle" attack and so their use is normally discouraged. | |
bc38a7d2 VD |
174 | These are excluded from the B<DEFAULT> ciphers, but included in the B<ALL> |
175 | ciphers. | |
176 | Be careful when building cipherlists out of lower-level primitives such as | |
177 | B<kDHE> or B<AES> as these do overlap with the B<aNULL> ciphers. | |
178 | When in doubt, include B<!aNULL> in your cipherlist. | |
