CIPHERS(1) OpenSSL CIPHERS(1)
NAME
ciphers - SSL cipher display and cipher list tool.
SYNOPSIS
openssl ciphers [-v] [-V] [-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.
-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.
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.
