7
9 openssl ciphers [-help] [-s] [-v] [-V] [-ssl3] [-tls1] [-tls1_1]
10 [-tls1_2] [-tls1_3] [-s] [-psk] [-srp] [-stdname] [-convert name]
11 [-ciphersuites val] [cipherlist]
12
14 The ciphers command converts textual OpenSSL cipher lists into ordered
15 SSL cipher preference lists. It can be used as a test tool to determine
16 the appropriate cipherlist.
17
19 -help
20 Print a usage message.
21
22 -s Only list supported ciphers: those consistent with the security
23 level, and minimum and maximum protocol version. This is closer to
24 the actual cipher list an application will support.
25
26 PSK and SRP ciphers are not enabled by default: they require -psk
27 or -srp to enable them.
28
29 It also does not change the default list of supported signature
30 algorithms.
31
32 On a server the list of supported ciphers might also exclude other
33 ciphers depending on the configured certificates and presence of DH
34 parameters.
35
36 If this option is not used then all ciphers that match the
37 cipherlist will be listed.
38
39 -psk
40 When combined with -s includes cipher suites which require PSK.
41
42 -srp
43 When combined with -s includes cipher suites which require SRP.
44
45 -v Verbose output: For each cipher suite, list details as provided by
46 SSL_CIPHER_description(3).
47
48 -V Like -v, but include the official cipher suite values in hex.
49
50 -tls1_3, -tls1_2, -tls1_1, -tls1, -ssl3
51 In combination with the -s option, list the ciphers which could be
52 used if the specified protocol were negotiated. Note that not all
53 protocols and flags may be available, depending on how OpenSSL was
54 built.
55
56 -stdname
57 Precede each cipher suite by its standard name.
58
59 -convert name
60 Convert a standard cipher name to its OpenSSL name.
61
62 -ciphersuites val
63 Sets the list of TLSv1.3 ciphersuites. This list will be combined
64 with any TLSv1.2 and below ciphersuites that have been configured.
65 The format for this list is a simple colon (":") separated list of
66 TLSv1.3 ciphersuite names. By default this value is:
67
68 TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256
69
70 cipherlist
71 A cipher list of TLSv1.2 and below ciphersuites to convert to a
72 cipher preference list. This list will be combined with any TLSv1.3
73 ciphersuites that have been configured. If it is not included then
74 the default cipher list will be used. The format is described
75 below.
76
78 The cipher list consists of one or more cipher strings separated by
79 colons. Commas or spaces are also acceptable separators but colons are
80 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 RC4-SHA.
85
86 It can represent a list of cipher suites containing a certain
87 algorithm, or cipher suites of a certain type. For example SHA1
88 represents all ciphers suites using the digest algorithm SHA1 and SSLv3
89 represents all SSL v3 algorithms.
90
91 Lists of cipher suites can be combined in a single cipher string using
92 the + character. This is used as a logical and operation. For example
93 SHA1+DES represents all cipher suites containing the SHA1 and the DES
94 algorithms.
95
96 Each cipher string can be optionally preceded by the characters !, - or
97 +.
98
99 If ! 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 - 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 + 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
108 ones.
109
110 If none of these characters is present then the string is just
111 interpreted as a list of ciphers to be appended to the current
112 preference list. If the list includes any ciphers already present they
113 will be ignored: that is they will not moved to the end of the list.
114
115 The cipher string @STRENGTH can be used at any point to sort the
116 current cipher list in order of encryption algorithm key length.
117
118 The cipher string @SECLEVEL=n can be used at any point to set the
119 security level to n, which should be a number between zero and five,
120 inclusive. See SSL_CTX_set_security_level for a description of what
121 each level means.
122
123 The cipher list can be prefixed with the DEFAULT keyword, which enables
124 the default cipher list as defined below. Unlike cipher strings, this
125 prefix may not be combined with other strings using + character. For
126 example, DEFAULT+DES is not valid.
127
128 The content of the default list is determined at compile time and
129 normally corresponds to ALL:!COMPLEMENTOFDEFAULT:!eNULL.
130
132 The following is a list of all permitted cipher strings and their
133 meanings.
134
135 COMPLEMENTOFDEFAULT
136 The ciphers included in ALL, but not enabled by default. Currently
137 this includes all RC4 and anonymous ciphers. Note that this rule
138 does not cover eNULL, which is not included by ALL (use
139 COMPLEMENTOFALL if necessary). Note that RC4 based cipher suites
140 are not built into OpenSSL by default (see the enable-weak-ssl-
141 ciphers option to Configure).
142
143 ALL All cipher suites except the eNULL ciphers (which must be
144 explicitly enabled if needed). As of OpenSSL 1.0.0, the ALL cipher
145 suites are sensibly ordered by default.
146
147 COMPLEMENTOFALL
148 The cipher suites not enabled by ALL, currently eNULL.
149
150 PROFILE=SYSTEM
151 The list of enabled cipher suites will be loaded from the system
152 crypto policy configuration file
153 /etc/crypto-policies/back-ends/openssl.config. See also
154 update-crypto-policies(8). This is the default behavior unless an
155 application explicitly sets a cipher list. If used in a cipher list
156 configuration value this string must be at the beginning of the
157 cipher list, otherwise it will not be recognized.
158
159 HIGH
160 "High" encryption cipher suites. This currently means those with
161 key lengths larger than 128 bits, and some cipher suites with
162 128-bit keys.
163
164 MEDIUM
165 "Medium" encryption cipher suites, currently some of those using
166 128 bit encryption.
167
168 LOW "Low" encryption cipher suites, currently those using 64 or 56 bit
169 encryption algorithms but excluding export cipher suites. All
170 these cipher suites have been removed as of OpenSSL 1.1.0.
171
172 eNULL, NULL
173 The "NULL" ciphers that is those offering no encryption. Because
174 these offer no encryption at all and are a security risk they are
175 not enabled via either the DEFAULT or ALL cipher strings. Be
176 careful when building cipherlists out of lower-level primitives
177 such as kRSA or aECDSA as these do overlap with the eNULL ciphers.
178 When in doubt, include !eNULL in your cipherlist.
179
180 aNULL
181 The cipher suites offering no authentication. This is currently the
182 anonymous DH algorithms and anonymous ECDH algorithms. These cipher
183 suites are vulnerable to "man in the middle" attacks and so their
184 use is discouraged. These are excluded from the DEFAULT ciphers,
185 but included in the ALL ciphers. Be careful when building
186 cipherlists out of lower-level primitives such as kDHE or AES as
187 these do overlap with the aNULL ciphers. When in doubt, include
188 !aNULL in your cipherlist.
189
190 kRSA, aRSA, RSA
191 Cipher suites using RSA key exchange or authentication. RSA is an
192 alias for kRSA.
193
194 kDHr, kDHd, kDH
195 Cipher suites using static DH key agreement and DH certificates
196 signed by CAs with RSA and DSS keys or either respectively. All
197 these cipher suites have been removed in OpenSSL 1.1.0.
198
199 kDHE, kEDH, DH
200 Cipher suites using ephemeral DH key agreement, including anonymous
201 cipher suites.
202
203 DHE, EDH
204 Cipher suites using authenticated ephemeral DH key agreement.
205
206 ADH Anonymous DH cipher suites, note that this does not include
207 anonymous Elliptic Curve DH (ECDH) cipher suites.
208
209 kEECDH, kECDHE, ECDH
210 Cipher suites using ephemeral ECDH key agreement, including
211 anonymous cipher suites.
212
213 ECDHE, EECDH
214 Cipher suites using authenticated ephemeral ECDH key agreement.
215
216 AECDH
217 Anonymous Elliptic Curve Diffie-Hellman cipher suites.
218
219 aDSS, DSS
220 Cipher suites using DSS authentication, i.e. the certificates carry
221 DSS keys.
222
223 aDH Cipher suites effectively using DH authentication, i.e. the
224 certificates carry DH keys. All these cipher suites have been
225 removed in OpenSSL 1.1.0.
226
227 aECDSA, ECDSA
228 Cipher suites using ECDSA authentication, i.e. the certificates
229 carry ECDSA keys.
230
231 TLSv1.2, TLSv1.0, SSLv3
232 Lists cipher suites which are only supported in at least TLS v1.2,
233 TLS v1.0 or SSL v3.0 respectively. Note: there are no cipher
234 suites specific to TLS v1.1. Since this is only the minimum
235 version, if, for example, TLSv1.0 is negotiated then both TLSv1.0
236 and SSLv3.0 cipher suites are available.
237
238 Note: these cipher strings do not change the negotiated version of
239 SSL or TLS, they only affect the list of available cipher suites.
240
241 AES128, AES256, AES
242 cipher suites using 128 bit AES, 256 bit AES or either 128 or 256
243 bit AES.
244
245 AESGCM
246 AES in Galois Counter Mode (GCM): these cipher suites are only
247 supported in TLS v1.2.
248
249 AESCCM, AESCCM8
250 AES in Cipher Block Chaining - Message Authentication Mode (CCM):
251 these cipher suites are only supported in TLS v1.2. AESCCM
252 references CCM cipher suites using both 16 and 8 octet Integrity
253 Check Value (ICV) while AESCCM8 only references 8 octet ICV.
254
255 ARIA128, ARIA256, ARIA
256 Cipher suites using 128 bit ARIA, 256 bit ARIA or either 128 or 256
257 bit ARIA.
258
259 CAMELLIA128, CAMELLIA256, CAMELLIA
260 Cipher suites using 128 bit CAMELLIA, 256 bit CAMELLIA or either
261 128 or 256 bit CAMELLIA.
262
263 CHACHA20
264 Cipher suites using ChaCha20.
265
266 3DES
267 Cipher suites using triple DES.
268
269 DES Cipher suites using DES (not triple DES). All these cipher suites
270 have been removed in OpenSSL 1.1.0.
271
272 RC4 Cipher suites using RC4.
273
274 RC2 Cipher suites using RC2.
275
276 IDEA
277 Cipher suites using IDEA.
278
279 SEED
280 Cipher suites using SEED.
281
282 MD5 Cipher suites using MD5.
283
284 SHA1, SHA
285 Cipher suites using SHA1.
286
287 SHA256, SHA384
288 Cipher suites using SHA256 or SHA384.
289
290 aGOST
291 Cipher suites using GOST R 34.10 (either 2001 or 94) for
292 authentication (needs an engine supporting GOST algorithms).
293
294 aGOST01
295 Cipher suites using GOST R 34.10-2001 authentication.
296
297 kGOST
298 Cipher suites, using VKO 34.10 key exchange, specified in the RFC
299 4357.
300
301 GOST94
302 Cipher suites, using HMAC based on GOST R 34.11-94.
303
304 GOST89MAC
305 Cipher suites using GOST 28147-89 MAC instead of HMAC.
306
307 PSK All cipher suites using pre-shared keys (PSK).
308
309 kPSK, kECDHEPSK, kDHEPSK, kRSAPSK
310 Cipher suites using PSK key exchange, ECDHE_PSK, DHE_PSK or
311 RSA_PSK.
312
313 aPSK
314 Cipher suites using PSK authentication (currently all PSK modes
315 apart from RSA_PSK).
316
317 SUITEB128, SUITEB128ONLY, SUITEB192
318 Enables suite B mode of operation using 128 (permitting 192 bit
319 mode by peer) 128 bit (not permitting 192 bit by peer) or 192 bit
320 level of security respectively. If used these cipherstrings should
321 appear first in the cipher list and anything after them is ignored.
322 Setting Suite B mode has additional consequences required to comply
323 with RFC6460. In particular the supported signature algorithms is
324 reduced to support only ECDSA and SHA256 or SHA384, only the
325 elliptic curves P-256 and P-384 can be used and only the two suite
326 B compliant cipher suites (ECDHE-ECDSA-AES128-GCM-SHA256 and
327 ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.
328
330 The following lists give the SSL or TLS cipher suites names from the
331 relevant specification and their OpenSSL equivalents. It should be
332 noted, that several cipher suite names do not include the
333 authentication used, e.g. DES-CBC3-SHA. In these cases, RSA
334 authentication is used.

622 Older names used by OpenSSL
623 The following names are accepted by older releases:
624
625 SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA EDH-RSA-DES-CBC3-SHA (DHE-RSA-DES-CBC3-SHA)
626 SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA EDH-DSS-DES-CBC3-SHA (DHE-DSS-DES-CBC3-SHA)
627
629 Some compiled versions of OpenSSL may not include all the ciphers
630 listed here because some ciphers were excluded at compile time.
631
633 Verbose listing of all OpenSSL ciphers including NULL ciphers:
634
635 openssl ciphers -v 'ALL:eNULL'
636
637 Include all ciphers except NULL and anonymous DH then sort by strength:
638
639 openssl ciphers -v 'ALL:!ADH:@STRENGTH'
640
641 Include all ciphers except ones with no encryption (eNULL) or no
642 authentication (aNULL):
643
644 openssl ciphers -v 'ALL:!aNULL'
645
646 Include only 3DES ciphers and then place RSA ciphers last:
647
648 openssl ciphers -v '3DES:+RSA'
649
650 Include all RC4 ciphers but leave out those without authentication:
651
652 openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
653
654 Include all ciphers with RSA authentication but leave out ciphers
655 without encryption.
656
657 openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
658
659 Set security level to 2 and display all ciphers consistent with level
660 2:
661
662 openssl ciphers -s -v 'ALL:@SECLEVEL=2'
663
665 s_client(1), s_server(1), ssl(7)
666
668 The -V option for the ciphers command was added in OpenSSL 1.0.0.
669
670 The -stdname is only available if OpenSSL is built with tracing enabled
671 (enable-ssl-trace argument to Configure) before OpenSSL 1.1.1.
672
673 The -convert option was added in OpenSSL 1.1.1.
