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 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

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. When in doubt, include !aNULL in your cipherlist.

kRSA, RSA
    cipher suites using RSA key exchange or authentication. RSA is an alias for kRSA.

kDHr, kDHd, kDH
    cipher suites using DH key agreement and DH certificates signed by CAs with RSA and DSS keys or either respectively.

kDHE, kEDH
    cipher suites using ephemeral DH key agreement, including anonymous cipher suites.

DHE, EDH
    cipher suites using authenticated ephemeral DH key agreement.

ADH anonymous DH cipher suites, note that this does not include anonymous Elliptic Curve DH (ECDH) cipher suites.

DH  cipher suites using DH, including anonymous DH, ephemeral DH and fixed DH.

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

kECDHE, kEECDH
    cipher suites using ephemeral ECDH key agreement, including anonymous cipher suites.

ECDHE, EECDH
    cipher suites using authenticated ephemeral ECDH key agreement.

AECDH
    anonymous Elliptic Curve Diffie Hellman cipher suites.

ECDH
    cipher suites using ECDH key exchange, including anonymous, ephemeral and fixed ECDH.

aRSA
    cipher suites using RSA authentication, i.e. the certificates carry RSA keys.

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

aDH cipher suites effectively using DH authentication, i.e. the certificates carry DH keys.

aECDH
    cipher suites effectively using ECDH authentication, i.e. the certificates carry ECDH keys.

aECDSA, ECDSA
    cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA keys.

kFZA, aFZA, eFZA, FZA
    ciphers suites using FORTEZZA key exchange, authentication, encryption or all FORTEZZA algorithms. Not implemented.

TLSv1.2, TLSv1, SSLv3, SSLv2
    TLS v1.2, TLS v1.0, SSL v3.0 or SSL v2.0 cipher suites respectively. Note: there are no ciphersuites specific to TLS v1.1.

AES128, AES256, AES
    cipher suites using 128 bit AES, 256 bit AES or either 128 or 256 bit AES.

AESGCM
    AES in Galois Counter Mode (GCM): these ciphersuites are only supported in TLS v1.2.

CAMELLIA128, CAMELLIA256, CAMELLIA
    cipher suites using 128 bit CAMELLIA, 256 bit CAMELLIA or either 128 or 256 bit CAMELLIA.

3DES
    cipher suites using triple DES.

DES cipher suites using DES (not triple DES).

RC4 cipher suites using RC4.

RC2 cipher suites using RC2.

IDEA
    cipher suites using IDEA.

SEED
    cipher suites using SEED.

MD5 cipher suites using MD5.

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.

GOST89MAC
    cipher suites using GOST 28147-89 MAC instead of HMAC.

PSK cipher suites using pre-shared keys (PSK).

SUITEB128, SUITEB128ONLY, SUITEB192
    enables suite B mode operation using 128 (permitting 192 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.
