CIPHERS(1SSL) OpenSSL CIPHERS(1SSL)NAME
openssl-ciphers, ciphers - SSL cipher display and cipher list tool
SYNOPSIS
openssl ciphers [-help] [-s] [-v] [-V] [-ssl3] [-tls1] [-tls1_1]
[-tls1_2] [-s] [-psk] [-srp] [-stdname] [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.
OPTIONS-help
Print a usage message.
-s Only list supported ciphers: those consistent with the security
level, and minimum and maximum protocol version. This is closer to
the actual cipher list an application will support.
PSK and SRP ciphers are not enabled by default: they require -psk
or -srp to enable them.
It also does not change the default list of supported signature
algorithms.
On a server the list of supported ciphers might also exclude other
ciphers depending on the configured certificates and presence of DH
parameters.
If this option is not used then all ciphers that match the
cipherlist will be listed.
-psk
When combined with -s includes cipher suites which require PSK.
-srp
When combined with -s includes cipher suites which require SRP.
-v Verbose output: For each ciphersuite, list details as provided by
SSL_CIPHER_description(3).
-V Like -v, but include the official cipher suite values in hex.
-tls1_2
In combination with the -s option, list the ciphers which would be
used if TLSv1.2 were negotiated.
-ssl3
In combination with the -s option, list the ciphers which would be
used if SSLv3 were negotiated.
-tls1
In combination with the -s option, list the ciphers which would be
used if TLSv1 were negotiated.
-tls1_1
In combination with the -s option, list the ciphers which would be
used if TLSv1.1 were negotiated.
-stdname
precede each ciphersuite by its standard name: only available is
OpenSSL is built with tracing enabled (enable-ssl-trace argument to
Configure).
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.
The cipher string @STRENGTH can be used at any point to sort the
current cipher list in order of encryption algorithm key length.
The cipher string @SECLEVEL=n can be used at any point to set the
security level to n.
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:!COMPLEMENTOFDEFAULT:!eNULL. When used, this must be
the first cipherstring specified.
COMPLEMENTOFDEFAULT
The ciphers included in ALL, but not enabled by default. Currently
this includes all RC4 and anonymous ciphers. Note that this rule
does not cover eNULL, which is not included by ALL (use
COMPLEMENTOFALL if necessary). Note that RC4 based ciphersuites are
not built into OpenSSL by default (see the enable-weak-ssl-ciphers
option to Configure).
ALL All cipher suites except the eNULL ciphers (which must be
explicitly enabled if needed). As of OpenSSL 1.0.0, the ALL cipher
suites are sensibly ordered by default.
COMPLEMENTOFALL
The cipher suites not enabled by ALL, currently 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" encryption cipher suites, currently those using 64 or 56 bit
encryption algorithms but excluding export cipher suites. All
these ciphersuites have been removed as of OpenSSL 1.1.0.
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 "man in the middle" attacks and so their
use is 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, aRSA, RSA
Cipher suites using RSA key exchange or authentication. RSA is an
alias for kRSA.
kDHr, kDHd, kDH
Cipher suites using static DH key agreement and DH certificates
signed by CAs with RSA and DSS keys or either respectively. All
these cipher suites have been removed in OpenSSL 1.1.0.
kDHE, kEDH, DH
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.
kEECDH, kECDHE, ECDH
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.
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. All these cipher suites have been
removed in OpenSSL 1.1.0.
aECDSA, ECDSA
Cipher suites using ECDSA authentication, i.e. the certificates
carry ECDSA keys.
TLSv1.2, TLSv1.0, SSLv3
Lists ciphersuites which are only supported in at least TLS v1.2,
TLS v1.0 or SSL v3.0 respectively. Note: there are no ciphersuites
specific to TLS v1.1. Since this is only the minimum version, if,
for example, TLSv1.0 is negotiated then both TLSv1.0 and SSLv3.0
ciphersuites are available.
Note: these cipher strings do not change the negotiated version of
SSL or TLS, they only affect the list of available cipher suites.
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.
AESCCM, AESCCM8
AES in Cipher Block Chaining - Message Authentication Mode (CCM):
these ciphersuites are only supported in TLS v1.2. AESCCM
references CCM cipher suites using both 16 and 8 octet Integrity
Check Value (ICV) while AESCCM8 only references 8 octet ICV.
CAMELLIA128, CAMELLIA256, CAMELLIA
cipher suites using 128 bit CAMELLIA, 256 bit CAMELLIA or either
128 or 256 bit CAMELLIA.
CHACHA20
cipher suites using ChaCha20.
3DES
cipher suites using triple DES.
DES Cipher suites using DES (not triple DES). All these cipher suites
have been removed in OpenSSL 1.1.0.
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
authentication (needs an engine supporting GOST algorithms).
aGOST01
Cipher suites using GOST R 34.10-2001 authentication.
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 All cipher suites using pre-shared keys (PSK).
kPSK, kECDHEPSK, kDHEPSK, kRSAPSK
Cipher suites using PSK key exchange, ECDHE_PSK, DHE_PSK or
RSA_PSK.
aPSK
Cipher suites using PSK authentication (currently all PSK modes
apart from RSA_PSK).
SUITEB128, SUITEB128ONLY, SUITEB192
Enables suite B mode of 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.

Older names used by OpenSSL
The following names are accepted by older releases:
SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA EDH-RSA-DES-CBC3-SHA (DHE-RSA-DES-CBC3-SHA)
SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA EDH-DSS-DES-CBC3-SHA (DHE-DSS-DES-CBC3-SHA)
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 ciphers with RSA authentication but leave out ciphers
without encryption.
openssl ciphers-v 'RSA:!COMPLEMENTOFALL'
Set security level to 2 and display all ciphers consistent with level
2:
openssl ciphers-s -v 'ALL:@SECLEVEL=2'
SEE ALSOs_client(1), s_server(1), ssl(7)HISTORY
The -V option for the ciphers command was added in OpenSSL 1.0.0.
