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
1.0.2t Last change: 2019-09-10 1
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
1.0.2t Last change: 2019-09-10 2
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)
ciphers. When in doubt, include !aNULL in your
cipherlist.

agreement.

certificates carry DSS keys.

1.0.2t Last change: 2019-09-10 5
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)

in the RFC 4357.

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:

CIPHERS(1) OpenSSL CIPHERS(1)
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.
