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 out 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 List the ciphers which would be used if SSL v3 was negotiated.
62 List the ciphers which would be used if TLS v1.0 was negotiated.
66 List the ciphers which would be used if TLS v1.1 was negotiated.
70 List the ciphers which would be used if TLS v1.2 was negotiated.
74 precede each ciphersuite by its standard name: only available is OpenSSL
75 is built with tracing enabled (B<enable-ssl-trace> argument to Configure).
79 a cipher list to convert to a cipher preference list. If it is not included
80 then the default cipher list will be used. The format is described below.
84 =head1 CIPHER LIST FORMAT
86 The cipher list consists of one or more I<cipher strings> separated by colons.
87 Commas or spaces are also acceptable separators but colons are normally used.
89 The actual cipher string can take several different forms.
91 It can consist of a single cipher suite such as B<RC4-SHA>.
93 It can represent a list of cipher suites containing a certain algorithm, or
94 cipher suites of a certain type. For example B<SHA1> represents all ciphers
95 suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3
98 Lists of cipher suites can be combined in a single cipher string using the
99 B<+> character. This is used as a logical B<and> operation. For example
100 B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
103 Each cipher string can be optionally preceded by the characters B<!>,
106 If B<!> 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
110 If B<-> 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.
113 If B<+> 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 ones.
116 If none of these characters is present then the string is just interpreted
117 as a list of ciphers to be appended to the current preference list. If the
118 list includes any ciphers already present they will be ignored: that is they
119 will not moved to the end of the list.
121 The cipher string B<@STRENGTH> can be used at any point to sort the current
122 cipher list in order of encryption algorithm key length.
124 The cipher string B<@SECLEVEL=n> can be used at any point to set the security
127 =head1 CIPHER STRINGS
129 The following is a list of all permitted cipher strings and their meanings.
135 the default cipher list. This is determined at compile time and
136 is B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>. This must be the first cipher
139 =item B<COMPLEMENTOFDEFAULT>
141 the ciphers included in B<ALL>, but not enabled by default. Currently
142 this includes all RC4, DES, RC2 and anonymous ciphers. Note that this rule does
143 not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if
148 all cipher suites except the B<eNULL> ciphers which must be explicitly enabled;
149 as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default
151 =item B<COMPLEMENTOFALL>
153 the cipher suites not enabled by B<ALL>, currently being B<eNULL>.
157 "high" encryption cipher suites. This currently means those with key lengths
158 larger than 128 bits, and some cipher suites with 128-bit keys.
162 "medium" encryption cipher suites, currently some of those using 128 bit
167 "low" encryption cipher suites, currently those using 64 or 56 bit
168 encryption algorithms but excluding export cipher suites. All these
169 ciphersuites have been removed as of OpenSSL 1.1.0.
171 =item B<eNULL>, B<NULL>
173 the "NULL" ciphers that is those offering no encryption. Because these offer no
174 encryption at all and are a security risk they are disabled unless explicitly
179 the cipher suites offering no authentication. This is currently the anonymous
180 DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable
181 to a "man in the middle" attack and so their use is normally discouraged.

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

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

317 ciphersuites using SHA256 or SHA384.
321 cipher suites using GOST R 34.10 (either 2001 or 94) for authentication

356 128 bit (not permitting 192 bit by peer) or 192 bit level of security
357 respectively. If used these cipherstrings should appear first in the cipher
358 list and anything after them is ignored. Setting Suite B mode has additional
359 consequences required to comply with RFC6460. In particular the supported
360 signature algorithms is reduced to support only ECDSA and SHA256 or SHA384,
361 only the elliptic curves P-256 and P-384 can be used and only the two suite B
362 compliant ciphersuites (ECDHE-ECDSA-AES128-GCM-SHA256 and
363 ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.

662 Some compiled versions of OpenSSL may not include all the ciphers
663 listed here because some ciphers were excluded at compile time.
667 Verbose listing of all OpenSSL ciphers including NULL ciphers:
669 openssl ciphers -v 'ALL:eNULL'
671 Include all ciphers except NULL and anonymous DH then sort by
674 openssl ciphers -v 'ALL:!ADH:@STRENGTH'
676 Include all ciphers except ones with no encryption (eNULL) or no
677 authentication (aNULL):
679 openssl ciphers -v 'ALL:!aNULL'
681 Include only 3DES ciphers and then place RSA ciphers last:
683 openssl ciphers -v '3DES:+RSA'
685 Include all RC4 ciphers but leave out those without authentication:
687 openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
689 Include all ciphers with RSA authentication but leave out ciphers without
692 openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
694 Set security level to 2 and display all ciphers consistent with level 2:
696 openssl ciphers -s -v 'ALL:@SECLEVEL=2'
