SYNOPSIS

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] [-provider name] [-provider-path path] [-propquery
12       propq] [cipherlist]
13

DESCRIPTION

15       This command converts textual OpenSSL cipher lists into ordered SSL
16       cipher preference lists. It can be used to determine the appropriate
17       cipherlist.
18

OPTIONS

20       -help
21           Print a usage message.
22
23       -provider name
24       -provider-path path
25       -propquery propq
26           See "Provider Options" in openssl(1), provider(7), and property(7).
27
28       -s  Only list supported ciphers: those consistent with the security
29           level, and minimum and maximum protocol version.  This is closer to
30           the actual cipher list an application will support.
31
32           PSK and SRP ciphers are not enabled by default: they require -psk
33           or -srp to enable them.
34
35           It also does not change the default list of supported signature
36           algorithms.
37
38           On a server the list of supported ciphers might also exclude other
39           ciphers depending on the configured certificates and presence of DH
40           parameters.
41
42           If this option is not used then all ciphers that match the
43           cipherlist will be listed.
44
45       -psk
46           When combined with -s includes cipher suites which require PSK.
47
48       -srp
49           When combined with -s includes cipher suites which require SRP.
50           This option is deprecated.
51
52       -v  Verbose output: For each cipher suite, list details as provided by
53           SSL_CIPHER_description(3).
54
55       -V  Like -v, but include the official cipher suite values in hex.
56
57       -tls1_3, -tls1_2, -tls1_1, -tls1, -ssl3
58           In combination with the -s option, list the ciphers which could be
59           used if the specified protocol were negotiated.  Note that not all
60           protocols and flags may be available, depending on how OpenSSL was
61           built.
62
63       -stdname
64           Precede each cipher suite by its standard name.
65
66       -convert name
67           Convert a standard cipher name to its OpenSSL name.
68
69       -ciphersuites val
70           Sets the list of TLSv1.3 ciphersuites. This list will be combined
71           with any TLSv1.2 and below ciphersuites that have been configured.
72           The format for this list is a simple colon (":") separated list of
73           TLSv1.3 ciphersuite names. By default this value is:
74
75            TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256
76
77       cipherlist
78           A cipher list of TLSv1.2 and below ciphersuites to convert to a
79           cipher preference list. This list will be combined with any TLSv1.3
80           ciphersuites that have been configured. If it is not included then
81           the default cipher list will be used. The format is described
82           below.
83

CIPHER LIST FORMAT

85       The cipher list consists of one or more cipher strings separated by
86       colons.  Commas or spaces are also acceptable separators but colons are
87       normally used.
88
89       The actual cipher string can take several different forms.
90
91       It can consist of a single cipher suite such as RC4-SHA.
92
93       It can represent a list of cipher suites containing a certain
94       algorithm, or cipher suites of a certain type. For example SHA1
95       represents all ciphers suites using the digest algorithm SHA1 and SSLv3
96       represents all SSL v3 algorithms.
97
98       Lists of cipher suites can be combined in a single cipher string using
99       the + character. This is used as a logical and operation. For example
100       SHA1+DES represents all cipher suites containing the SHA1 and the DES
101       algorithms.
102
103       Each cipher string can be optionally preceded by the characters !, - or
104       +.
105
106       If ! is used then the ciphers are permanently deleted from the list.
107       The ciphers deleted can never reappear in the list even if they are
108       explicitly stated.
109
110       If - is used then the ciphers are deleted from the list, but some or
111       all of the ciphers can be added again by later options.
112
113       If + is used then the ciphers are moved to the end of the list. This
114       option doesn't add any new ciphers it just moves matching existing
115       ones.
116
117       If none of these characters is present then the string is just
118       interpreted as a list of ciphers to be appended to the current
119       preference list. If the list includes any ciphers already present they
120       will be ignored: that is they will not moved to the end of the list.
121
122       The cipher string @STRENGTH can be used at any point to sort the
123       current cipher list in order of encryption algorithm key length.
124
125       The cipher string @SECLEVEL=n can be used at any point to set the
126       security level to n, which should be a number between zero and five,
127       inclusive.  See SSL_CTX_set_security_level(3) for a description of what
128       each level means.
129
130       The cipher list can be prefixed with the DEFAULT keyword, which enables
131       the default cipher list as defined below.  Unlike cipher strings, this
132       prefix may not be combined with other strings using + character.  For
133       example, DEFAULT+DES is not valid.
134
135       The content of the default list is determined at compile time and
136       normally corresponds to ALL:!COMPLEMENTOFDEFAULT:!eNULL.
137

CIPHER STRINGS

139       The following is a list of all permitted cipher strings and their
140       meanings.
141
142       COMPLEMENTOFDEFAULT
143           The ciphers included in ALL, but not enabled by default. Currently
144           this includes all RC4 and anonymous ciphers. Note that this rule
145           does not cover eNULL, which is not included by ALL (use
146           COMPLEMENTOFALL if necessary). Note that RC4 based cipher suites
147           are not built into OpenSSL by default (see the enable-weak-ssl-
148           ciphers option to Configure).
149
150       ALL All cipher suites except the eNULL ciphers (which must be
151           explicitly enabled if needed).  As of OpenSSL 1.0.0, the ALL cipher
152           suites are sensibly ordered by default.
153
154       COMPLEMENTOFALL
155           The cipher suites not enabled by ALL, currently eNULL.
156
157       PROFILE=SYSTEM
158           The list of enabled cipher suites will be loaded from the system
159           crypto policy configuration file
160           /etc/crypto-policies/back-ends/openssl.config.  See also
161           update-crypto-policies(8).  This is the default behavior unless an
162           application explicitly sets a cipher list. If used in a cipher list
163           configuration value this string must be at the beginning of the
164           cipher list, otherwise it will not be recognized.
165
166       HIGH
167           "High" encryption cipher suites. This currently means those with
168           key lengths larger than 128 bits, and some cipher suites with
169           128-bit keys.
170
171       MEDIUM
172           "Medium" encryption cipher suites, currently some of those using
173           128 bit encryption.
174
175       LOW "Low" encryption cipher suites, currently those using 64 or 56 bit
176           encryption algorithms but excluding export cipher suites.  All
177           these cipher suites have been removed as of OpenSSL 1.1.0.
178
179       eNULL, NULL
180           The "NULL" ciphers that is those offering no encryption. Because
181           these offer no encryption at all and are a security risk they are
182           not enabled via either the DEFAULT or ALL cipher strings.  Be
183           careful when building cipherlists out of lower-level primitives
184           such as kRSA or aECDSA as these do overlap with the eNULL ciphers.
185           When in doubt, include !eNULL in your cipherlist.
186
187       aNULL
188           The cipher suites offering no authentication. This is currently the
189           anonymous DH algorithms and anonymous ECDH algorithms. These cipher
190           suites are vulnerable to "man in the middle" attacks and so their
191           use is discouraged.  These are excluded from the DEFAULT ciphers,
192           but included in the ALL ciphers.  Be careful when building
193           cipherlists out of lower-level primitives such as kDHE or AES as
194           these do overlap with the aNULL ciphers.  When in doubt, include
195           !aNULL in your cipherlist.
196
197       kRSA, aRSA, RSA
198           Cipher suites using RSA key exchange or authentication. RSA is an
199           alias for kRSA.
200
201       kDHr, kDHd, kDH
202           Cipher suites using static DH key agreement and DH certificates
203           signed by CAs with RSA and DSS keys or either respectively.  All
204           these cipher suites have been removed in OpenSSL 1.1.0.
205
206       kDHE, kEDH, DH
207           Cipher suites using ephemeral DH key agreement, including anonymous
208           cipher suites.
209
210       DHE, EDH
211           Cipher suites using authenticated ephemeral DH key agreement.
212
213       ADH Anonymous DH cipher suites, note that this does not include
214           anonymous Elliptic Curve DH (ECDH) cipher suites.
215
216       kEECDH, kECDHE, ECDH
217           Cipher suites using ephemeral ECDH key agreement, including
218           anonymous cipher suites.
219
220       ECDHE, EECDH
221           Cipher suites using authenticated ephemeral ECDH key agreement.
222
223       AECDH
224           Anonymous Elliptic Curve Diffie-Hellman cipher suites.
225
226       aDSS, DSS
227           Cipher suites using DSS authentication, i.e. the certificates carry
228           DSS keys.
229
230       aDH Cipher suites effectively using DH authentication, i.e. the
231           certificates carry DH keys.  All these cipher suites have been
232           removed in OpenSSL 1.1.0.
233
234       aECDSA, ECDSA
235           Cipher suites using ECDSA authentication, i.e. the certificates
236           carry ECDSA keys.
237
238       TLSv1.2, TLSv1.0, SSLv3
239           Lists cipher suites which are only supported in at least TLS v1.2,
240           TLS v1.0 or SSL v3.0 respectively.  Note: there are no cipher
241           suites specific to TLS v1.1.  Since this is only the minimum
242           version, if, for example, TLSv1.0 is negotiated then both TLSv1.0
243           and SSLv3.0 cipher suites are available.
244
245           Note: these cipher strings do not change the negotiated version of
246           SSL or TLS, they only affect the list of available cipher suites.
247
248       AES128, AES256, AES
249           cipher suites using 128 bit AES, 256 bit AES or either 128 or 256
250           bit AES.
251
252       AESGCM
253           AES in Galois Counter Mode (GCM): these cipher suites are only
254           supported in TLS v1.2.
255
256       AESCCM, AESCCM8
257           AES in Cipher Block Chaining - Message Authentication Mode (CCM):
258           these cipher suites are only supported in TLS v1.2. AESCCM
259           references CCM cipher suites using both 16 and 8 octet Integrity
260           Check Value (ICV) while AESCCM8 only references 8 octet ICV.
261
262       ARIA128, ARIA256, ARIA
263           Cipher suites using 128 bit ARIA, 256 bit ARIA or either 128 or 256
264           bit ARIA.
265
266       CAMELLIA128, CAMELLIA256, CAMELLIA
267           Cipher suites using 128 bit CAMELLIA, 256 bit CAMELLIA or either
268           128 or 256 bit CAMELLIA.
269
270       CHACHA20
271           Cipher suites using ChaCha20.
272
273       3DES
274           Cipher suites using triple DES.
275
276       DES Cipher suites using DES (not triple DES).  All these cipher suites
277           have been removed in OpenSSL 1.1.0.
278
279       RC4 Cipher suites using RC4.
280
281       RC2 Cipher suites using RC2.
282
283       IDEA
284           Cipher suites using IDEA.
285
286       SEED
287           Cipher suites using SEED.
288
289       MD5 Cipher suites using MD5.
290
291       SHA1, SHA
292           Cipher suites using SHA1.
293
294       SHA256, SHA384
295           Cipher suites using SHA256 or SHA384.
296
297       aGOST
298           Cipher suites using GOST R 34.10 (either 2001 or 94) for
299           authentication (needs an engine supporting GOST algorithms).
300
301       aGOST01
302           Cipher suites using GOST R 34.10-2001 authentication.
303
304       kGOST
305           Cipher suites, using VKO 34.10 key exchange, specified in the RFC
306           4357.
307
308       GOST94
309           Cipher suites, using HMAC based on GOST R 34.11-94.
310
311       GOST89MAC
312           Cipher suites using GOST 28147-89 MAC instead of HMAC.
313
314       PSK All cipher suites using pre-shared keys (PSK).
315
316       kPSK, kECDHEPSK, kDHEPSK, kRSAPSK
317           Cipher suites using PSK key exchange, ECDHE_PSK, DHE_PSK or
318           RSA_PSK.
319
320       aPSK
321           Cipher suites using PSK authentication (currently all PSK modes
322           apart from RSA_PSK).
323
324       SUITEB128, SUITEB128ONLY, SUITEB192
325           Enables suite B mode of operation using 128 (permitting 192 bit
326           mode by peer) 128 bit (not permitting 192 bit by peer) or 192 bit
327           level of security respectively.  If used these cipherstrings should
328           appear first in the cipher list and anything after them is ignored.
329           Setting Suite B mode has additional consequences required to comply
330           with RFC6460.  In particular the supported signature algorithms is
331           reduced to support only ECDSA and SHA256 or SHA384, only the
332           elliptic curves P-256 and P-384 can be used and only the two suite
333           B compliant cipher suites (ECDHE-ECDSA-AES128-GCM-SHA256 and
334           ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.
335
336       CBC All cipher suites using encryption algorithm in Cipher Block
337           Chaining (CBC) mode. These cipher suites are only supported in TLS
338           v1.2 and earlier. Currently it's an alias for the following
339           cipherstrings: SSL_DES, SSL_3DES, SSL_RC2, SSL_IDEA, SSL_AES128,
340           SSL_AES256, SSL_CAMELLIA128, SSL_CAMELLIA256, SSL_SEED.
341

CIPHER SUITE NAMES

343       The following lists give the SSL or TLS cipher suites names from the
344       relevant specification and their OpenSSL equivalents. It should be
345       noted, that several cipher suite names do not include the
346       authentication used, e.g. DES-CBC3-SHA. In these cases, RSA
347       authentication is used.

647   Older names used by OpenSSL
648       The following names are accepted by older releases:
649
650        SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA    EDH-RSA-DES-CBC3-SHA (DHE-RSA-DES-CBC3-SHA)

NOTES

654       Some compiled versions of OpenSSL may not include all the ciphers
655       listed here because some ciphers were excluded at compile time.
656

EXAMPLES

658       Verbose listing of all OpenSSL ciphers including NULL ciphers:
659
660        openssl ciphers -v 'ALL:eNULL'
661
662       Include all ciphers except NULL and anonymous DH then sort by strength:
663
664        openssl ciphers -v 'ALL:!ADH:@STRENGTH'
665
666       Include all ciphers except ones with no encryption (eNULL) or no
667       authentication (aNULL):
668
669        openssl ciphers -v 'ALL:!aNULL'
670
671       Include only 3DES ciphers and then place RSA ciphers last:
672
673        openssl ciphers -v '3DES:+RSA'
674
675       Include all RC4 ciphers but leave out those without authentication:
676
677        openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
678
679       Include all ciphers with RSA authentication but leave out ciphers
680       without encryption.
681
682        openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
683
684       Set security level to 2 and display all ciphers consistent with level
685       2:
686
687        openssl ciphers -s -v 'ALL:@SECLEVEL=2'

HISTORY

693       The -V option was added in OpenSSL 1.0.0.
694
695       The -stdname is only available if OpenSSL is built with tracing enabled
696       (enable-ssl-trace argument to Configure) before OpenSSL 1.1.1.
697
698       The -convert option was added in OpenSSL 1.1.1.
