6 ciphers - SSL cipher display and cipher list tool.
7
9 openssl ciphers [-v] [-V] [-ssl3] [-tls1] [cipherlist]
10
12 The ciphers command converts textual OpenSSL cipher lists into ordered
13 SSL cipher preference lists. It can be used as a test tool to determine
14 the appropriate cipherlist.
15
17 -v Verbose option. List ciphers with a complete description of
18 protocol version (SSLv2 or SSLv3; the latter includes TLS), key
19 exchange, authentication, encryption and mac algorithms used along
20 with any key size restrictions and whether the algorithm is classed
21 as an "export" cipher. Note that without the -v option, ciphers
22 may seem to appear twice in a cipher list; this is when similar
23 ciphers are available for SSL v2 and for SSL v3/TLS v1.
24 -V Like -v, but include cipher suite codes in output (hex format).
26 -ssl3, -tls1
28 This lists ciphers compatible with any of SSLv3, TLSv1, TLSv1.1 or
29 TLSv1.2.
30 -h, -?
32 Print a brief usage message.
33 cipherlist
35 A cipher list to convert to a cipher preference list. If it is not
36 included then the default cipher list will be used. The format is
37 described below.
38
40 The cipher list consists of one or more cipher strings separated by
41 colons. Commas or spaces are also acceptable separators but colons are
42 normally used.
43 The actual cipher string can take several different forms.
45 It can consist of a single cipher suite such as RC4-SHA.
47 It can represent a list of cipher suites containing a certain
49 algorithm, or cipher suites of a certain type. For example SHA1
50 represents all ciphers suites using the digest algorithm SHA1 and SSLv3
51 represents all SSL v3 algorithms.
52 Lists of cipher suites can be combined in a single cipher string using
54 the + character. This is used as a logical and operation. For example
55 SHA1+DES represents all cipher suites containing the SHA1 and the DES
56 algorithms.
57 Each cipher string can be optionally preceded by the characters !, - or
59 +.
60 If ! is used then the ciphers are permanently deleted from the list.
62 The ciphers deleted can never reappear in the list even if they are
63 explicitly stated.
64 If - is used then the ciphers are deleted from the list, but some or
66 all of the ciphers can be added again by later options.
67 If + is used then the ciphers are moved to the end of the list. This
69 option doesn't add any new ciphers it just moves matching existing
70 ones.
71 If none of these characters is present then the string is just
73 interpreted as a list of ciphers to be appended to the current
74 preference list. If the list includes any ciphers already present they
75 will be ignored: that is they will not moved to the end of the list.
76 Additionally the cipher string @STRENGTH can be used at any point to
78 sort the current cipher list in order of encryption algorithm key
79 length.
80
82 The following is a list of all permitted cipher strings and their
83 meanings.
84 DEFAULT
86 The default cipher list. This is determined at compile time and is
87 normally ALL:!EXPORT:!LOW:!aNULL:!eNULL:!SSLv2. When used, this
88 must be the first cipherstring specified.
89 COMPLEMENTOFDEFAULT
91 the ciphers included in ALL, but not enabled by default. Currently
92 this is ADH and AECDH. Note that this rule does not cover eNULL,
93 which is not included by ALL (use COMPLEMENTOFALL if necessary).
94 ALL all cipher suites except the eNULL ciphers which must be explicitly
96 enabled; as of OpenSSL, the ALL cipher suites are reasonably
97 ordered by default
98 COMPLEMENTOFALL
100 the cipher suites not enabled by ALL, currently being eNULL.
101 HIGH
103 "high" encryption cipher suites. This currently means those with
104 key lengths larger than 128 bits, and some cipher suites with
105 128-bit keys.
106 MEDIUM
108 "medium" encryption cipher suites, currently some of those using
109 128 bit encryption.
110 LOW Low strength encryption cipher suites, currently those using 64 or
112 56 bit encryption algorithms but excluding export cipher suites.
113 As of OpenSSL 1.0.2g, these are disabled in default builds.
114 EXP, EXPORT
116 Export strength encryption algorithms. Including 40 and 56 bits
117 algorithms. As of OpenSSL 1.0.2g, these are disabled in default
118 builds.
119 EXPORT40
121 40-bit export encryption algorithms As of OpenSSL 1.0.2g, these are
122 disabled in default builds.
123 EXPORT56
125 56-bit export encryption algorithms. In OpenSSL 0.9.8c and later
126 the set of 56 bit export ciphers is empty unless OpenSSL has been
127 explicitly configured with support for experimental ciphers. As of
128 OpenSSL 1.0.2g, these are disabled in default builds.
129 eNULL, NULL
131 The "NULL" ciphers that is those offering no encryption. Because
132 these offer no encryption at all and are a security risk they are
133 not enabled via either the DEFAULT or ALL cipher strings. Be
134 careful when building cipherlists out of lower-level primitives
135 such as kRSA or aECDSA as these do overlap with the eNULL ciphers.
136 When in doubt, include !eNULL in your cipherlist.
137 aNULL
139 The cipher suites offering no authentication. This is currently the
140 anonymous DH algorithms and anonymous ECDH algorithms. These cipher
141 suites are vulnerable to a "man in the middle" attack and so their
142 use is normally discouraged. These are excluded from the DEFAULT
143 ciphers, but included in the ALL ciphers. Be careful when building
144 cipherlists out of lower-level primitives such as kDHE or AES as
145 these do overlap with the aNULL ciphers. When in doubt, include
146 !aNULL in your cipherlist.
147 kRSA, RSA
149 cipher suites using RSA key exchange.
150 kDHr, kDHd, kDH
152 cipher suites using DH key agreement and DH certificates signed by
153 CAs with RSA and DSS keys or either respectively.
154 kDHE, kEDH
156 cipher suites using ephemeral DH key agreement, including anonymous
157 cipher suites.
158 DHE, EDH
160 cipher suites using authenticated ephemeral DH key agreement.
161 ADH anonymous DH cipher suites, note that this does not include
163 anonymous Elliptic Curve DH (ECDH) cipher suites.
164 DH cipher suites using DH, including anonymous DH, ephemeral DH and
166 fixed DH.
167 kECDHr, kECDHe, kECDH
169 cipher suites using fixed ECDH key agreement signed by CAs with RSA
170 and ECDSA keys or either respectively.
171 kECDHE, kEECDH

181 ECDH
183 cipher suites using ECDH key exchange, including anonymous,
184 ephemeral and fixed ECDH.
185 aRSA
187 cipher suites using RSA authentication, i.e. the certificates carry
188 RSA keys.
189 aDSS, DSS
191 cipher suites using DSS authentication, i.e. the certificates carry
192 DSS keys.
193 aDH cipher suites effectively using DH authentication, i.e. the
195 certificates carry DH keys.
196 aECDH
198 cipher suites effectively using ECDH authentication, i.e. the
199 certificates carry ECDH keys.
200 aECDSA, ECDSA
202 cipher suites using ECDSA authentication, i.e. the certificates
203 carry ECDSA keys.
204 kFZA, aFZA, eFZA, FZA
206 ciphers suites using FORTEZZA key exchange, authentication,
207 encryption or all FORTEZZA algorithms. Not implemented.
208 TLSv1.2, TLSv1, SSLv3, SSLv2
210 TLS v1.2, TLS v1.0, SSL v3.0 or SSL v2.0 cipher suites
211 respectively. Note: there are no ciphersuites specific to TLS v1.1.
212 AES128, AES256, AES
214 cipher suites using 128 bit AES, 256 bit AES or either 128 or 256
215 bit AES.
216 AESGCM
218 AES in Galois Counter Mode (GCM): these ciphersuites are only
219 supported in TLS v1.2.
220 CAMELLIA128, CAMELLIA256, CAMELLIA
222 cipher suites using 128 bit CAMELLIA, 256 bit CAMELLIA or either
223 128 or 256 bit CAMELLIA.

247 aGOST
249 cipher suites using GOST R 34.10 (either 2001 or 94) for
250 authenticaction (needs an engine supporting GOST algorithms).
251 aGOST01
253 cipher suites using GOST R 34.10-2001 authentication.
254 aGOST94
256 cipher suites using GOST R 34.10-94 authentication (note that R
257 34.10-94 standard has been expired so use GOST R 34.10-2001)
258 kGOST
260 cipher suites, using VKO 34.10 key exchange, specified in the RFC
261 4357.
262 GOST94
264 cipher suites, using HMAC based on GOST R 34.11-94.
265 GOST89MAC
267 cipher suites using GOST 28147-89 MAC instead of HMAC.
268 PSK cipher suites using pre-shared keys (PSK).
270 SUITEB128, SUITEB128ONLY, SUITEB192
272 enables suite B mode operation using 128 (permitting 192 bit mode
273 by peer) 128 bit (not permitting 192 bit by peer) or 192 bit level
274 of security respectively. If used these cipherstrings should appear
275 first in the cipher list and anything after them is ignored.
276 Setting Suite B mode has additional consequences required to comply
277 with RFC6460. In particular the supported signature algorithms is
278 reduced to support only ECDSA and SHA256 or SHA384, only the
279 elliptic curves P-256 and P-384 can be used and only the two suite
280 B compliant ciphersuites (ECDHE-ECDSA-AES128-GCM-SHA256 and
281 ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.
282
284 The following lists give the SSL or TLS cipher suites names from the
285 relevant specification and their OpenSSL equivalents. It should be
286 noted, that several cipher suite names do not include the
287 authentication used, e.g. DES-CBC3-SHA. In these cases, RSA
288 authentication is used.

518 Some compiled versions of OpenSSL may not include all the ciphers
519 listed here because some ciphers were excluded at compile time.

522 Verbose listing of all OpenSSL ciphers including NULL ciphers:
523 openssl ciphers -v 'ALL:eNULL'
525 Include all ciphers except NULL and anonymous DH then sort by strength:
527 openssl ciphers -v 'ALL:!ADH:@STRENGTH'
529 Include all ciphers except ones with no encryption (eNULL) or no
531 authentication (aNULL):
532 openssl ciphers -v 'ALL:!aNULL'
534 Include only 3DES ciphers and then place RSA ciphers last:
536 openssl ciphers -v '3DES:+RSA'
538 Include all RC4 ciphers but leave out those without authentication:
540 openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
542 Include all chiphers with RSA authentication but leave out ciphers
544 without encryption.
545 openssl ciphers -v 'RSA:!COMPLEMENTOFALL'

552 The COMPLENTOFALL and COMPLEMENTOFDEFAULT selection options for
553 cipherlist strings were added in OpenSSL 0.9.7. The -V option for the
554 ciphers command was added in OpenSSL 1.0.0.
