5 ciphers - SSL cipher display and cipher list tool.
24 The B<ciphers> command converts textual OpenSSL cipher lists into ordered
25 SSL cipher preference lists. It can be used as a test tool to determine
26 the appropriate cipherlist.
28 =head1 COMMAND OPTIONS
34 Only list supported ciphers: those consistent with the security level. This
35 is the actual cipher list an application will support. If this option is
36 not used then ciphers excluded by the security level will still be listed.
40 When combined with B<-s> includes cipher suites which require PSK.
44 Verbose option. List ciphers with a complete description of
45 protocol version, key exchange,
46 authentication, encryption and mac algorithms used along with any key size
47 restrictions and whether the algorithm is classed as an "export" cipher.
51 Like B<-v>, but include cipher suite codes in output (hex format).
55 List the ciphers which would be used if SSL v3 was negotiated.
59 List the ciphers which would be used if TLS v1.0 was negotiated.
63 List the ciphers which would be used if TLS v1.1 was negotiated.
67 List the ciphers which would be used if TLS v1.2 was negotiated.
71 precede each ciphersuite by its standard name: only available is OpenSSL
72 is built with tracing enabled (B<enable-ssl-trace> argument to Configure).
76 print a brief usage message.
80 a cipher list to convert to a cipher preference list. If it is not included
81 then the default cipher list will be used. The format is described below.
85 =head1 CIPHER LIST FORMAT
87 The cipher list consists of one or more I<cipher strings> separated by colons.
88 Commas or spaces are also acceptable separators but colons are normally used.
90 The actual cipher string can take several different forms.
92 It can consist of a single cipher suite such as B<RC4-SHA>.
94 It can represent a list of cipher suites containing a certain algorithm, or
95 cipher suites of a certain type. For example B<SHA1> represents all ciphers
96 suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3
99 Lists of cipher suites can be combined in a single cipher string using the
100 B<+> character. This is used as a logical B<and> operation. For example
101 B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
104 Each cipher string can be optionally preceded by the characters B<!>,
107 If B<!> is used then the ciphers are permanently deleted from the list.
108 The ciphers deleted can never reappear in the list even if they are
111 If B<-> is used then the ciphers are deleted from the list, but some or
112 all of the ciphers can be added again by later options.
114 If B<+> is used then the ciphers are moved to the end of the list. This
115 option doesn't add any new ciphers it just moves matching existing ones.
117 If none of these characters is present then the string is just interpreted
118 as a list of ciphers to be appended to the current preference list. If the
119 list includes any ciphers already present they will be ignored: that is they
120 will not moved to the end of the list.
122 The cipher string B<@STRENGTH> can be used at any point to sort the current
123 cipher list in order of encryption algorithm key length.
125 The cipher string B<@SECLEVEL=n> can be used at any point to set the security
128 =head1 CIPHER STRINGS
130 The following is a list of all permitted cipher strings and their meanings.
136 the default cipher list. This is determined at compile time and
137 is B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>. This must be the first cipher
140 =item B<COMPLEMENTOFDEFAULT>
142 the ciphers included in B<ALL>, but not enabled by default. Currently
143 this includes all RC4, DES, RC2 and anonymous ciphers. Note that this rule does
144 not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if
149 all cipher suites except the B<eNULL> ciphers which must be explicitly enabled;
150 as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default
152 =item B<COMPLEMENTOFALL>
154 the cipher suites not enabled by B<ALL>, currently being B<eNULL>.
158 "high" encryption cipher suites. This currently means those with key lengths
159 larger than 128 bits, and some cipher suites with 128-bit keys.
163 "medium" encryption cipher suites, currently some of those using 128 bit
168 "low" encryption cipher suites, currently those using 64 or 56 bit encryption
169 algorithms but excluding export cipher suites.
171 =item B<EXP>, B<EXPORT>
173 export encryption algorithms. Including 40 and 56 bits algorithms.
177 40 bit export encryption algorithms
181 56 bit export encryption algorithms. This list is empty.
183 =item B<eNULL>, B<NULL>
185 the "NULL" ciphers that is those offering no encryption. Because these offer no
186 encryption at all and are a security risk they are disabled unless explicitly
191 the cipher suites offering no authentication. This is currently the anonymous
192 DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable
193 to a "man in the middle" attack and so their use is normally discouraged.

211 cipher suites using authenticated ephemeral DH key agreement.

259 =item B<aECDSA>, B<ECDSA>
261 cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA
264 =item B<TLSv1.2>, B<TLSv1.0>, B<SSLv3>
266 Lists ciphersuites which are only supported in at least TLS v1.2, TLS v1.0
267 or SSL v3.0 respectively. Note: there are no ciphersuites specific to TLS v1.1.
268 Since this is only the minimum version if, for example, TLS v1.0 is supported
269 then both TLS v1.0 and SSL v3.0 ciphersuites are included.
271 Note: these cipher strings B<do not> change the negotiated version of SSL or
272 TLS only the list of cipher suites.
274 =item B<AES128>, B<AES256>, B<AES>
276 cipher suites using 128 bit AES, 256 bit AES or either 128 or 256 bit AES.

286 ciphersuites are only supported in TLS v1.2. B<AESCCM> references CCM
287 cipher suites using both 16 and 8 octet Integrity Check Value (ICV)
288 while B<AESCCM8> only references 8 octet ICV.
290 =item B<CAMELLIA128>, B<CAMELLIA256>, B<CAMELLIA>

329 ciphersuites using SHA256 or SHA384.
333 cipher suites using GOST R 34.10 (either 2001 or 94) for authentication
334 (needs an engine supporting GOST algorithms).

368 128 bit (not permitting 192 bit by peer) or 192 bit level of security
369 respectively. If used these cipherstrings should appear first in the cipher
370 list and anything after them is ignored. Setting Suite B mode has additional
371 consequences required to comply with RFC6460. In particular the supported
372 signature algorithms is reduced to support only ECDSA and SHA256 or SHA384,
373 only the elliptic curves P-256 and P-384 can be used and only the two suite B
374 compliant ciphersuites (ECDHE-ECDSA-AES128-GCM-SHA256 and
375 ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.

382 relevant specification and their OpenSSL equivalents. It should be noted,
383 that several cipher suite names do not include the authentication used,

706 Some compiled versions of OpenSSL may not include all the ciphers
707 listed here because some ciphers were excluded at compile time.
711 Verbose listing of all OpenSSL ciphers including NULL ciphers:
713 openssl ciphers -v 'ALL:eNULL'
715 Include all ciphers except NULL and anonymous DH then sort by
718 openssl ciphers -v 'ALL:!ADH:@STRENGTH'
720 Include all ciphers except ones with no encryption (eNULL) or no
721 authentication (aNULL):
723 openssl ciphers -v 'ALL:!aNULL'
725 Include only 3DES ciphers and then place RSA ciphers last:
727 openssl ciphers -v '3DES:+RSA'
729 Include all RC4 ciphers but leave out those without authentication:
731 openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
733 Include all ciphers with RSA authentication but leave out ciphers without
736 openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
738 Set security level to 2 and display all ciphers consistent with level 2:
