5 ciphers - SSL cipher display and cipher list tool.
25 The B<ciphers> command converts textual OpenSSL cipher lists into ordered
26 SSL cipher preference lists. It can be used as a test tool to determine
27 the appropriate cipherlist.
29 =head1 COMMAND OPTIONS
35 Print a usage message.
39 Only list supported ciphers: those consistent with the security level. This
40 is the actual cipher list an application will support. If this option is
41 not used then ciphers excluded by the security level will still be listed.
45 When combined with B<-s> includes cipher suites which require PSK.
49 Verbose output: For each ciphersuite, list details as provided by
50 L<SSL_CIPHER_description(3)>.
54 Like B<-v>, but include the official cipher suite values in hex.
58 In combination with the B<-s> option, list the ciphers which would be used if
59 TLSv1.2 were negotiated.
63 In combination with the B<-s> option, list the ciphers which would be used if
64 SSLv3 were negotiated.
68 In combination with the B<-s> option, list the ciphers which would be used if
69 TLSv1 were negotiated.
73 In combination with the B<-s> option, list the ciphers which would be used if
74 TLSv1.1 were negotiated.

79 is built with tracing enabled (B<enable-ssl-trace> argument to Configure).
83 a cipher list to convert to a cipher preference list. If it is not included
84 then the default cipher list will be used. The format is described below.
88 =head1 CIPHER LIST FORMAT
90 The cipher list consists of one or more I<cipher strings> separated by colons.
91 Commas or spaces are also acceptable separators but colons are normally used.
93 The actual cipher string can take several different forms.
95 It can consist of a single cipher suite such as B<RC4-SHA>.
97 It can represent a list of cipher suites containing a certain algorithm, or
98 cipher suites of a certain type. For example B<SHA1> represents all ciphers
99 suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3
102 Lists of cipher suites can be combined in a single cipher string using the
103 B<+> character. This is used as a logical B<and> operation. For example
104 B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
107 Each cipher string can be optionally preceded by the characters B<!>,
110 If B<!> is used then the ciphers are permanently deleted from the list.
111 The ciphers deleted can never reappear in the list even if they are
114 If B<-> is used then the ciphers are deleted from the list, but some or
115 all of the ciphers can be added again by later options.
117 If B<+> is used then the ciphers are moved to the end of the list. This
118 option doesn't add any new ciphers it just moves matching existing ones.
120 If none of these characters is present then the string is just interpreted
121 as a list of ciphers to be appended to the current preference list. If the
122 list includes any ciphers already present they will be ignored: that is they
123 will not moved to the end of the list.
125 The cipher string B<@STRENGTH> can be used at any point to sort the current
126 cipher list in order of encryption algorithm key length.
128 The cipher string B<@SECLEVEL=n> can be used at any point to set the security
131 =head1 CIPHER STRINGS
133 The following is a list of all permitted cipher strings and their meanings.
139 The default cipher list.
140 This is determined at compile time and is normally
141 B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>.
142 When used, this must be the first cipherstring specified.
144 =item B<COMPLEMENTOFDEFAULT>
146 The ciphers included in B<ALL>, but not enabled by default. Currently
147 this includes all RC4, DES, RC2 and anonymous ciphers. Note that this rule does
148 not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if
153 All cipher suites except the B<eNULL> ciphers (which must be explicitly enabled
155 As of OpenSSL 1.0.0, the B<ALL> cipher suites are sensibly ordered by default.
157 =item B<COMPLEMENTOFALL>
159 The cipher suites not enabled by B<ALL>, currently B<eNULL>.
163 "high" encryption cipher suites. This currently means those with key lengths
164 larger than 128 bits, and some cipher suites with 128-bit keys.
168 "medium" encryption cipher suites, currently some of those using 128 bit
173 "low" encryption cipher suites, currently those using 64 or 56 bit
174 encryption algorithms but excluding export cipher suites. All these
175 ciphersuites have been removed as of OpenSSL 1.1.0.
177 =item B<eNULL>, B<NULL>
179 The "NULL" ciphers that is those offering no encryption. Because these offer no
180 encryption at all and are a security risk they are not enabled via either the
181 B<DEFAULT> or B<ALL> cipher strings.
182 Be careful when building cipherlists out of lower-level primitives such as
183 B<kRSA> or B<aECDSA> as these do overlap with the B<eNULL> ciphers. When in
184 doubt, include B<!eNULL> in your cipherlist.
188 The cipher suites offering no authentication. This is currently the anonymous
189 DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable
190 to "man in the middle" attacks and so their use is discouraged.
191 These are excluded from the B<DEFAULT> ciphers, but included in the B<ALL>
193 Be careful when building cipherlists out of lower-level primitives such as
194 B<kDHE> or B<AES> as these do overlap with the B<aNULL> ciphers.
195 When in doubt, include B<!aNULL> in your cipherlist.
197 =item B<kRSA>, B<aRSA>, B<RSA>
199 Cipher suites using RSA key exchange, authentication or either respectively.
201 =item B<kDHr>, B<kDHd>, B<kDH>

249 =item B<TLSv1.2>, B<TLSv1.0>, B<SSLv3>
251 Lists ciphersuites which are only supported in at least TLS v1.2, TLS v1.0 or
252 SSL v3.0 respectively.
253 Note: there are no ciphersuites specific to TLS v1.1.
254 Since this is only the minimum version, if, for example, TLSv1.0 is negotiated
255 then both TLSv1.0 and SSLv3.0 ciphersuites are available.
257 Note: these cipher strings B<do not> change the negotiated version of SSL or
258 TLS, they only affect the list of available cipher suites.
260 =item B<AES128>, B<AES256>, B<AES>
262 cipher suites using 128 bit AES, 256 bit AES or either 128 or 256 bit AES.
266 AES in Galois Counter Mode (GCM): these ciphersuites are only supported
269 =item B<AESCCM>, B<AESCCM8>

272 ciphersuites are only supported in TLS v1.2. B<AESCCM> references CCM
273 cipher suites using both 16 and 8 octet Integrity Check Value (ICV)

361 If used these cipherstrings should appear first in the cipher
362 list and anything after them is ignored.
363 Setting Suite B mode has additional consequences required to comply with
365 In particular the supported signature algorithms is reduced to support only
366 ECDSA and SHA256 or SHA384, only the elliptic curves P-256 and P-384 can be
367 used and only the two suite B compliant ciphersuites

652 Some compiled versions of OpenSSL may not include all the ciphers
653 listed here because some ciphers were excluded at compile time.
657 Verbose listing of all OpenSSL ciphers including NULL ciphers:
659 openssl ciphers -v 'ALL:eNULL'
661 Include all ciphers except NULL and anonymous DH then sort by
664 openssl ciphers -v 'ALL:!ADH:@STRENGTH'
666 Include all ciphers except ones with no encryption (eNULL) or no
667 authentication (aNULL):
669 openssl ciphers -v 'ALL:!aNULL'
671 Include only 3DES ciphers and then place RSA ciphers last:
673 openssl ciphers -v '3DES:+RSA'
675 Include all RC4 ciphers but leave out those without authentication:
677 openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
679 Include all ciphers with RSA authentication but leave out ciphers without
682 openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
684 Set security level to 2 and display all ciphers consistent with level 2:
686 openssl ciphers -s -v 'ALL:@SECLEVEL=2'
690 L<s_client(1)>, L<s_server(1)>, L<ssl(3)>
694 The B<-V> option for the B<ciphers> command was added in OpenSSL 1.0.0.
