NAME

6       openssl-ciphers, ciphers - SSL cipher display and cipher list tool
7

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] [cipherlist]
12

DESCRIPTION

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

OPTIONS

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

CIPHER LIST FORMAT

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

CIPHER STRINGS

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

CIPHER SUITE NAMES

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.

NOTES

629       Some compiled versions of OpenSSL may not include all the ciphers
630       listed here because some ciphers were excluded at compile time.
631

EXAMPLES

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'

HISTORY

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.
