5 ciphers - SSL cipher display and cipher list tool.
20 The B<ciphers> command converts textual OpenSSL cipher lists into ordered
21 SSL cipher preference lists. It can be used as a test tool to determine
22 the appropriate cipherlist.
24 =head1 COMMAND OPTIONS
30 Only list supported ciphers: those consistent with the security level. This
31 is the actual cipher list an application will support. If this option is
32 not used then ciphers excluded by the security level will still be listed.
36 Verbose option. List ciphers with a complete description of
37 protocol version, key exchange,
38 authentication, encryption and mac algorithms used along with any key size
39 restrictions and whether the algorithm is classed as an "export" cipher.
43 Like B<-v>, but include cipher suite codes in output (hex format).
47 only include SSL v3 ciphers.
51 only include TLS v1 ciphers.
55 precede each ciphersuite by its standard name: only available is OpenSSL
56 is built with tracing enabled (B<enable-ssl-trace> argument to Configure).
60 print a brief usage message.
64 a cipher list to convert to a cipher preference list. If it is not included
65 then the default cipher list will be used. The format is described below.
69 =head1 CIPHER LIST FORMAT
71 The cipher list consists of one or more I<cipher strings> separated by colons.
72 Commas or spaces are also acceptable separators but colons are normally used.
74 The actual cipher string can take several different forms.
76 It can consist of a single cipher suite such as B<RC4-SHA>.
78 It can represent a list of cipher suites containing a certain algorithm, or
79 cipher suites of a certain type. For example B<SHA1> represents all ciphers
80 suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3
83 Lists of cipher suites can be combined in a single cipher string using the
84 B<+> character. This is used as a logical B<and> operation. For example
85 B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
88 Each cipher string can be optionally preceded by the characters B<!>,
91 If B<!> is used then the ciphers are permanently deleted from the list.
92 The ciphers deleted can never reappear in the list even if they are
95 If B<-> is used then the ciphers are deleted from the list, but some or
96 all of the ciphers can be added again by later options.
98 If B<+> is used then the ciphers are moved to the end of the list. This
99 option doesn't add any new ciphers it just moves matching existing ones.
101 If none of these characters is present then the string is just interpreted
102 as a list of ciphers to be appended to the current preference list. If the
103 list includes any ciphers already present they will be ignored: that is they
104 will not moved to the end of the list.
106 The cipher string B<@STRENGTH> can be used at any point to sort the current
107 cipher list in order of encryption algorithm key length.
109 The cipher string B<@SECLEVEL=n> can be used at any point to set the security
112 =head1 CIPHER STRINGS
114 The following is a list of all permitted cipher strings and their meanings.
120 the default cipher list. This is determined at compile time and
121 is B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>. This must be the first cipher
124 =item B<COMPLEMENTOFDEFAULT>
126 the ciphers included in B<ALL>, but not enabled by default. Currently
127 this includes all RC4, DES, RC2 and anonymous ciphers. Note that this rule does
128 not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if
133 all cipher suites except the B<eNULL> ciphers which must be explicitly enabled;
134 as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default
136 =item B<COMPLEMENTOFALL>
138 the cipher suites not enabled by B<ALL>, currently being B<eNULL>.
142 "high" encryption cipher suites. This currently means those with key lengths
143 larger than 128 bits, and some cipher suites with 128-bit keys.
147 "medium" encryption cipher suites, currently some of those using 128 bit
152 "low" encryption cipher suites, currently those using 64 or 56 bit encryption
153 algorithms but excluding export cipher suites.
155 =item B<EXP>, B<EXPORT>
157 export encryption algorithms. Including 40 and 56 bits algorithms.
161 40 bit export encryption algorithms
165 56 bit export encryption algorithms. This list is empty.
167 =item B<eNULL>, B<NULL>
169 the "NULL" ciphers that is those offering no encryption. Because these offer no
170 encryption at all and are a security risk they are disabled unless explicitly
175 the cipher suites offering no authentication. This is currently the anonymous
176 DH algorithms and anonymous ECDH algorithms. These cipher suites are vulnerable
177 to a "man in the middle" attack and so their use is normally discouraged.

248 =item B<TLSv1.2>, B<TLSv1>, B<SSLv3>
250 TLS v1.2, TLS v1.0 or SSL v3.0 cipher suites respectively. Note:

347 128 bit (not permitting 192 bit by peer) or 192 bit level of security
348 respectively. If used these cipherstrings should appear first in the cipher
349 list and anything after them is ignored. Setting Suite B mode has additional
350 consequences required to comply with RFC6460. In particular the supported
351 signature algorithms is reduced to support only ECDSA and SHA256 or SHA384,
352 only the elliptic curves P-256 and P-384 can be used and only the two suite B
353 compliant ciphersuites (ECDHE-ECDSA-AES128-GCM-SHA256 and
354 ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.

685 Some compiled versions of OpenSSL may not include all the ciphers
686 listed here because some ciphers were excluded at compile time.
690 Verbose listing of all OpenSSL ciphers including NULL ciphers:
692 openssl ciphers -v 'ALL:eNULL'
694 Include all ciphers except NULL and anonymous DH then sort by
697 openssl ciphers -v 'ALL:!ADH:@STRENGTH'
699 Include all ciphers except ones with no encryption (eNULL) or no
700 authentication (aNULL):
702 openssl ciphers -v 'ALL:!aNULL'
704 Include only 3DES ciphers and then place RSA ciphers last:
706 openssl ciphers -v '3DES:+RSA'
708 Include all RC4 ciphers but leave out those without authentication:
710 openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
712 Include all ciphers with RSA authentication but leave out ciphers without
715 openssl ciphers -v 'RSA:!COMPLEMENTOFALL'
717 Set security level to 2 and display all ciphers consistent with level 2:
