CIPHERS(1)                   OpenSSL                   CIPHERS(1)


NAME

     openssl-ciphers, ciphers - SSL cipher display and cipher
     list tool.


SYNOPSIS

     openssl ciphers [-v] [-V] [-ssl2] [-ssl3] [-tls1]
     [cipherlist]


DESCRIPTION

     The ciphers command converts textual OpenSSL cipher lists
     into ordered SSL cipher preference lists. It can be used as
     a test tool to determine the appropriate cipherlist.


COMMAND OPTIONS

     -v  Verbose option. List ciphers with a complete description
         of protocol version (SSLv2 or SSLv3; the latter includes
         TLS), key exchange, authentication, encryption and mac
         algorithms used along with any key size restrictions and
         whether the algorithm is classed as an "export" cipher.
         Note that without the -v option, ciphers may seem to
         appear twice in a cipher list; this is when similar
         ciphers are available for SSL v2 and for SSL v3/TLS v1.

     -V  Like -v, but include cipher suite codes in output (hex
         format).

     -ssl3, -tls1
         This lists ciphers compatible with any of SSLv3, TLSv1,
         TLSv1.1 or TLSv1.2.

     -ssl2
         Only include SSLv2 ciphers.

     -h, -?
         Print a brief usage message.

     cipherlist
         A cipher list to convert to a cipher preference list. If
         it is not included then the default cipher list will be
         used. The format is described below.


CIPHER LIST FORMAT

     The cipher list consists of one or more cipher strings
     separated by colons.  Commas or spaces are also acceptable
     separators but colons are normally used.

     The actual cipher string can take several different forms.

     It can consist of a single cipher suite such as RC4-SHA.

     It can represent a list of cipher suites containing a
     certain algorithm, or cipher suites of a certain type. For

CIPHERS(1)                   OpenSSL                   CIPHERS(1)

     example SHA1 represents all ciphers suites using the digest
     algorithm SHA1 and SSLv3 represents all SSL v3 algorithms.

     Lists of cipher suites can be combined in a single cipher
     string using the + character. This is used as a logical and
     operation. For example SHA1+DES represents all cipher suites
     containing the SHA1 and the DES algorithms.

     Each cipher string can be optionally preceded by the
     characters !, - or +.

     If ! is used then the ciphers are permanently deleted from
     the list.  The ciphers deleted can never reappear in the
     list even if they are explicitly stated.

     If - is used then the ciphers are deleted from the list, but
     some or all of the ciphers can be added again by later
     options.

     If + is used then the ciphers are moved to the end of the
     list. This option doesn't add any new ciphers it just moves
     matching existing ones.

     If none of these characters is present then the string is
     just interpreted as a list of ciphers to be appended to the
     current preference list. If the list includes any ciphers
     already present they will be ignored: that is they will not
     moved to the end of the list.

     Additionally the cipher string @STRENGTH can be used at any
     point to sort the current cipher list in order of encryption
     algorithm key length.


CIPHER STRINGS

     The following is a list of all permitted cipher strings and
     their meanings.

     DEFAULT
         The default cipher list.  This is determined at compile
         time and is normally
         ALL:!EXPORT:!LOW:!aNULL:!eNULL:!SSLv2.  When used, this
         must be the first cipherstring specified.

     COMPLEMENTOFDEFAULT
         the ciphers included in ALL, but not enabled by default.
         Currently this is ADH and AECDH. Note that this rule
         does not cover eNULL, which is not included by ALL (use
         COMPLEMENTOFALL if necessary).

     ALL all cipher suites except the eNULL ciphers which must be
         explicitly enabled; as of OpenSSL, the ALL cipher suites
         are reasonably ordered by default

CIPHERS(1)                   OpenSSL                   CIPHERS(1)

     COMPLEMENTOFALL
         the cipher suites not enabled by ALL, currently being
         eNULL.

     HIGH
         "high" encryption cipher suites. This currently means
         those with key lengths larger than 128 bits, and some
         cipher suites with 128-bit keys.

     MEDIUM
         "medium" encryption cipher suites, currently some of
         those using 128 bit encryption.

     LOW Low strength encryption cipher suites, currently those
         using 64 or 56 bit encryption algorithms but excluding
         export cipher suites.  As of OpenSSL 1.0.2g, these are
         disabled in default builds.

     EXP, EXPORT
         Export strength encryption algorithms. Including 40 and
         56 bits algorithms.  As of OpenSSL 1.0.2g, these are
         disabled in default builds.

     EXPORT40
         40-bit export encryption algorithms As of OpenSSL
         1.0.2g, these are disabled in default builds.

     EXPORT56
         56-bit export encryption algorithms. In OpenSSL 0.9.8c
         and later the set of 56 bit export ciphers is empty
         unless OpenSSL has been explicitly configured with
         support for experimental ciphers.  As of OpenSSL 1.0.2g,
         these are disabled in default builds.

     eNULL, NULL
         The "NULL" ciphers that is those offering no encryption.
         Because these offer no encryption at all and are a
         security risk they are not enabled via either the
         DEFAULT or ALL cipher strings.  Be careful when building
         cipherlists out of lower-level primitives such as kRSA
         or aECDSA as these do overlap with the eNULL ciphers.
         When in doubt, include !eNULL in your cipherlist.

     aNULL
         The cipher suites offering no authentication. This is
         currently the anonymous DH algorithms and anonymous ECDH
         algorithms. These cipher suites are vulnerable to a "man
         in the middle" attack and so their use is normally
         discouraged.  These are excluded from the DEFAULT
         ciphers, but included in the ALL ciphers.  Be careful
         when building cipherlists out of lower-level primitives
         such as kDHE or AES as these do overlap with the aNULL

CIPHERS(1)                   OpenSSL                   CIPHERS(1)

     SHA1, SHA
         cipher suites using SHA1.

     SHA256, SHA384
         ciphersuites using SHA256 or SHA384.

     aGOST
         cipher suites using GOST R 34.10 (either 2001 or 94) for
         authenticaction (needs an engine supporting GOST
         algorithms).

     aGOST01
         cipher suites using GOST R 34.10-2001 authentication.

     aGOST94
         cipher suites using GOST R 34.10-94 authentication (note
         that R 34.10-94 standard has been expired so use GOST R
         34.10-2001)

     kGOST
         cipher suites, using VKO 34.10 key exchange, specified
         in the RFC 4357.

     GOST94
         cipher suites, using HMAC based on GOST R 34.11-94.

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


CIPHER SUITE NAMES

     The following lists give the SSL or TLS cipher suites names
     from the relevant specification and their OpenSSL
     equivalents. It should be noted, that several cipher suite
     names do not include the authentication used, e.g.
     DES-CBC3-SHA. In these cases, RSA authentication is used.

NOTES

     Some compiled versions of OpenSSL may not include all the
     ciphers listed here because some ciphers were excluded at
     compile time.


EXAMPLES

     Verbose listing of all OpenSSL ciphers including NULL
     ciphers:

      openssl ciphers -v 'ALL:eNULL'

     Include all ciphers except NULL and anonymous DH then sort
     by strength:

      openssl ciphers -v 'ALL:!ADH:@STRENGTH'

     Include all ciphers except ones with no encryption (eNULL)
     or no authentication (aNULL):

      openssl ciphers -v 'ALL:!aNULL'

     Include only 3DES ciphers and then place RSA ciphers last:

      openssl ciphers -v '3DES:+RSA'

     Include all RC4 ciphers but leave out those without
     authentication:

      openssl ciphers -v 'RC4:!COMPLEMENTOFDEFAULT'

     Include all chiphers with RSA authentication but leave out
     ciphers without encryption.

      openssl ciphers -v 'RSA:!COMPLEMENTOFALL'

HISTORY

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