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
169 encryption algorithms but excluding export cipher suites. All these
170 ciphersuites have been removed as of OpenSSL 1.1.0.
172 =item B<eNULL>, B<NULL>
174 the "NULL" ciphers that is those offering no encryption. Because these offer no
175 encryption at all and are a security risk they are disabled unless explicitly
180 the cipher suites offering no authentication. This is currently the anonymous
181 DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable
182 to a "man in the middle" attack and so their use is normally discouraged.

250 cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA
253 =item B<TLSv1.2>, B<TLSv1.0>, B<SSLv3>
255 Lists ciphersuites which are only supported in at least TLS v1.2, TLS v1.0
256 or SSL v3.0 respectively. Note: there are no ciphersuites specific to TLS v1.1.
257 Since this is only the minimum version if, for example, TLS v1.0 is supported
258 then both TLS v1.0 and SSL v3.0 ciphersuites are included.
260 Note: these cipher strings B<do not> change the negotiated version of SSL or
261 TLS only the list of cipher suites.
263 =item B<AES128>, B<AES256>, B<AES>

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

318 ciphersuites using SHA256 or SHA384.
322 cipher suites using GOST R 34.10 (either 2001 or 94) for authentication
323 (needs an engine supporting GOST algorithms).

357 128 bit (not permitting 192 bit by peer) or 192 bit level of security
358 respectively. If used these cipherstrings should appear first in the cipher
359 list and anything after them is ignored. Setting Suite B mode has additional
360 consequences required to comply with RFC6460. In particular the supported
361 signature algorithms is reduced to support only ECDSA and SHA256 or SHA384,
362 only the elliptic curves P-256 and P-384 can be used and only the two suite B
363 compliant ciphersuites (ECDHE-ECDSA-AES128-GCM-SHA256 and
364 ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.

663 Some compiled versions of OpenSSL may not include all the ciphers
664 listed here because some ciphers were excluded at compile time.
668 Verbose listing of all OpenSSL ciphers including NULL ciphers:
670 openssl ciphers -v 'ALL:eNULL'
672 Include all ciphers except NULL and anonymous DH then sort by
675 openssl ciphers -v 'ALL:!ADH:@STRENGTH'
677 Include all ciphers except ones with no encryption (eNULL) or no
678 authentication (aNULL):
680 openssl ciphers -v 'ALL:!aNULL'
682 Include only 3DES ciphers and then place RSA ciphers last:
684 openssl ciphers -v '3DES:+RSA'
686 Include all RC4 ciphers but leave out those without authentication:
688 openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
690 Include all ciphers with RSA authentication but leave out ciphers without
693 openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
695 Set security level to 2 and display all ciphers consistent with level 2:
697 openssl ciphers -s -v 'ALL:@SECLEVEL=2'
