6 ciphers - SSL cipher display and cipher list tool.
7
9 openssl ciphers [-v] [-V] [-ssl2] [-ssl3] [-tls1] [cipherlist]
10
12 The ciphers command converts textual OpenSSL cipher lists into ordered
13 SSL cipher preference lists. It can be used as a test tool to determine
14 the appropriate cipherlist.
15
17 -v Verbose option. List ciphers with a complete description of
18 protocol version (SSLv2 or SSLv3; the latter includes TLS), key
19 exchange, authentication, encryption and mac algorithms used along
20 with any key size restrictions and whether the algorithm is classed
21 as an "export" cipher. Note that without the -v option, ciphers
22 may seem to appear twice in a cipher list; this is when similar
23 ciphers are available for SSL v2 and for SSL v3/TLS v1.
24 -V Like -v, but include cipher suite codes in output (hex format).
26 -ssl3
28 only include SSL v3 ciphers.
29 -ssl2
31 only include SSL v2 ciphers.
32 -tls1
34 only include TLS v1 ciphers.
35 -h, -?
37 print a brief usage message.
38 cipherlist
40 a cipher list to convert to a cipher preference list. If it is not
41 included then the default cipher list will be used. The format is
42 described below.
43
45 The cipher list consists of one or more cipher strings separated by
46 colons. Commas or spaces are also acceptable separators but colons are
47 normally used.
48 The actual cipher string can take several different forms.
50 It can consist of a single cipher suite such as RC4-SHA.
52 It can represent a list of cipher suites containing a certain
54 algorithm, or cipher suites of a certain type. For example SHA1
55 represents all ciphers suites using the digest algorithm SHA1 and SSLv3
56 represents all SSL v3 algorithms.
57 Lists of cipher suites can be combined in a single cipher string using
59 the + character. This is used as a logical and operation. For example
60 SHA1+DES represents all cipher suites containing the SHA1 and the DES
61 algorithms.
62 Each cipher string can be optionally preceded by the characters !, - or
64 +.
65 If ! is used then the ciphers are permanently deleted from the list.
67 The ciphers deleted can never reappear in the list even if they are
68 explicitly stated.
69 If - is used then the ciphers are deleted from the list, but some or
71 all of the ciphers can be added again by later options.
72 If + is used then the ciphers are moved to the end of the list. This
74 option doesn't add any new ciphers it just moves matching existing
75 ones.
76 If none of these characters is present then the string is just
78 interpreted as a list of ciphers to be appended to the current
79 preference list. If the list includes any ciphers already present they
80 will be ignored: that is they will not moved to the end of the list.
81 Additionally the cipher string @STRENGTH can be used at any point to
83 sort the current cipher list in order of encryption algorithm key
84 length.
85
87 The following is a list of all permitted cipher strings and their
88 meanings.
89 DEFAULT
91 the default cipher list. This is determined at compile time and, as
92 of OpenSSL 1.0.0, is normally ALL:!aNULL:!eNULL. This must be the
93 first cipher string specified.
94 COMPLEMENTOFDEFAULT
96 the ciphers included in ALL, but not enabled by default. Currently
97 this is ADH and AECDH. Note that this rule does not cover eNULL,
98 which is not included by ALL (use COMPLEMENTOFALL if necessary).
99 ALL all cipher suites except the eNULL ciphers which must be explicitly
101 enabled; as of OpenSSL, the ALL cipher suites are reasonably
102 ordered by default
103 COMPLEMENTOFALL
105 the cipher suites not enabled by ALL, currently being eNULL.
106 HIGH
108 "high" encryption cipher suites. This currently means those with
109 key lengths larger than 128 bits, and some cipher suites with
110 128-bit keys.
111 MEDIUM
113 "medium" encryption cipher suites, currently some of those using
114 128 bit encryption.
115 LOW "low" encryption cipher suites, currently those using 64 or 56 bit
117 encryption algorithms but excluding export cipher suites.
118 EXP, EXPORT
120 export encryption algorithms. Including 40 and 56 bits algorithms.
121 EXPORT40
123 40 bit export encryption algorithms
124 EXPORT56
126 56 bit export encryption algorithms. In OpenSSL 0.9.8c and later
127 the set of 56 bit export ciphers is empty unless OpenSSL has been
128 explicitly configured with support for experimental ciphers.
129 eNULL, NULL
131 the "NULL" ciphers that is those offering no encryption. Because
132 these offer no encryption at all and are a security risk they are
133 disabled unless explicitly included.
134 aNULL
136 the cipher suites offering no authentication. This is currently the
137 anonymous DH algorithms and anonymous ECDH algorithms. These cipher
138 suites are vulnerable to a "man in the middle" attack and so their
139 use is normally discouraged.
140 kRSA, RSA
142 cipher suites using RSA key exchange.
143 kDHr, kDHd, kDH
145 cipher suites using DH key agreement and DH certificates signed by
146 CAs with RSA and DSS keys or either respectively. Not implemented.

150 cipher suites.

158 fixed DH.
159 kECDHr, kECDHe, kECDH
161 cipher suites using fixed ECDH key agreement signed by CAs with RSA
162 and ECDSA keys or either respectively.

183 cipher suites using DSS authentication, i.e. the certificates carry
184 DSS keys.

187 certificates carry DH keys. Not implemented.
188 aECDH
190 cipher suites effectively using ECDH authentication, i.e. the

500 The non-ephemeral DH modes are currently unimplemented in OpenSSL
501 because there is no support for DH certificates.
502 Some compiled versions of OpenSSL may not include all the ciphers
504 listed here because some ciphers were excluded at compile time.
505
507 Verbose listing of all OpenSSL ciphers including NULL ciphers:
508 openssl ciphers -v 'ALL:eNULL'
510 Include all ciphers except NULL and anonymous DH then sort by strength:
512 openssl ciphers -v 'ALL:!ADH:@STRENGTH'
514 Include all ciphers except ones with no encryption (eNULL) or no
516 authentication (aNULL):
517 openssl ciphers -v 'ALL:!aNULL'
519 Include only 3DES ciphers and then place RSA ciphers last:
521 openssl ciphers -v '3DES:+RSA'
523 Include all RC4 ciphers but leave out those without authentication:
525 openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'
527 Include all chiphers with RSA authentication but leave out ciphers
529 without encryption.
530 openssl ciphers -v 'RSA:!COMPLEMENTOFALL'

537 The COMPLENTOFALL and COMPLEMENTOFDEFAULT selection options for
538 cipherlist strings were added in OpenSSL 0.9.7. The -V option for the
539 ciphers command was added in OpenSSL 1.0.0.
