NAME

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:!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.

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.
