NAME
openssl-ciphers - SSL cipher display and cipher list command
SYNOPSIS
openssl ciphers [-help] [-s] [-v] [-V] [-ssl3] [-tls1] [-tls1_1]
[-tls1_2] [-tls1_3] [-psk] [-srp] [-stdname] [-convert name]
[-ciphersuites val] [-provider name] [-provider-path path] [-provparam
[name:]key=value] [-propquery propq] [cipherlist]
DESCRIPTION
This command converts textual OpenSSL cipher lists into ordered SSL
cipher preference lists. It can be used to determine the appropriate
cipherlist.
OPTIONS
-help
Print a usage message.
-provider name
-provider-path path
-provparam [name:]key=value
-propquery propq
See "Provider Options" in openssl(1), provider(7), and property(7).
-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.
This option is deprecated.
-v Verbose output: For each cipher suite, list details as provided by
SSL_CIPHER_description(3).
-V Like -v, but include the official cipher suite values in hex.
-tls1_3, -tls1_2, -tls1_1, -tls1, -ssl3
In combination with the -s option, list the ciphers which could be
used if the specified protocol were negotiated. Note that not all
protocols and flags may be available, depending on how OpenSSL was
built.
-stdname
Precede each cipher suite by its standard name.
-convert name
Convert a standard cipher name to its OpenSSL name.
-ciphersuites val
Sets the list of TLSv1.3 ciphersuites. This list will be combined
with any TLSv1.2 and below ciphersuites that have been configured.
The format for this list is a simple colon (":") separated list of
TLSv1.3 ciphersuite names. By default this value is:
TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256
cipherlist
A cipher list of TLSv1.2 and below ciphersuites to convert to a
cipher preference list. This list will be combined with any TLSv1.3
ciphersuites that have been configured. 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 cipher string may reference a cipher using its standard name from
the IANA TLS Cipher Suites Registry
(<https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4>).
The actual cipher string can take several different forms.
It can consist of a single cipher suite such as AES256-SHA.
It can represent a list of cipher suites containing a certain
algorithm, or cipher suites of a certain type. For example SHA256
represents all cipher suites using the digest algorithm SHA256 and
TLSv1.2 represents all cipher suites introduced in TLS v.1.2.
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
SHA256+AES represents all cipher suites using the SHA256 and the AES
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, which should be a number between zero and five,
inclusive. See SSL_CTX_set_security_level(3) for a description of what
each level means.
The cipher list can be prefixed with the DEFAULT keyword, which enables
the default cipher list as defined below. Unlike cipher strings, this
prefix may not be combined with other strings using + character. For
example, DEFAULT+AES is not valid.
The content of the default list is determined at compile time and
normally corresponds to ALL:!COMPLEMENTOFDEFAULT:!eNULL.
CIPHER STRINGS
The following is a list of all permitted cipher strings and their
meanings.
COMPLEMENTOFDEFAULT
The cipher suites included in ALL, but not enabled by default. The
default cipher suite list provides strong security and reasonable
interoperability. A cipher suite can be not included in the
default list for different reasons: because it is weak, or not
"mature" enough, or not widely used, etc. 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 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 cipher suites have been removed as of OpenSSL 1.1.0.
FIPS
Cipher suites permitted in FIPS mode.
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, RSA authentication, or both
of them respectively.
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.
aECDSA, ECDSA
Cipher suites using ECDSA authentication, i.e. the certificates
carry ECDSA keys.
TLSv1.2, TLSv1.0, SSLv3
Lists cipher suites introduced in TLS v1.2, TLS v1.0 or SSL v3.0
respectively. Note: there are no cipher suites 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 cipher suites
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 cipher suites are only
supported in TLS v1.2.
AESCCM, AESCCM8
AES in Cipher Block Chaining - Message Authentication Mode (CCM):
these cipher suites 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.
ARIA128, ARIA256
Cipher suites using 128 bit ARIA or 256 bit ARIA respectively.
ARIA, ARIAGCM
Cipher suites using either 128 or 256 bit ARIA.
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

SHA256, SHA384
Cipher suites using SHA256 or SHA384.
aGOST
Cipher suites using GOST R 34.10 (either 2001 or 2012) for
authentication (needs an engine supporting GOST algorithms).
aGOST01
Cipher suites that can be uses with GOST R 34.10-2001 keys for
authentication.
aGOST12
Cipher suites that can be used with GOST R 34.10-2012 keys for

7836 and KExp15 key export specified in the RFC 9189.
GOST94
Cipher suites, using HMAC based on GOST R 34.11-94.
GOST12
Cipher suites, using HMAC based on GOST R 34.11-2012 256 bits.

Z.
GOST89
Cipher suites using any GOST cipher (GOST 28147-89, Magma or
Kuznyechik).
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.

apart from RSA_PSK).
kSRP, SRP

aSRP
Cipher suites using SRP authentication.
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 cipher suites (ECDHE-ECDSA-AES128-GCM-SHA256 and
ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.
CBC All cipher suites using encryption algorithm in Cipher Block
Chaining (CBC) mode. These cipher suites are only supported in TLS
v1.2 and earlier. Currently it's an alias for the following
cipherstrings: SSL_DES, SSL_3DES, SSL_RC2, SSL_IDEA, SSL_AES128,
SSL_AES256, SSL_CAMELLIA128, SSL_CAMELLIA256, SSL_SEED.
CIPHER SUITE NAMES
The following lists give the standard SSL or TLS cipher suites names
from the relevant specification and their OpenSSL equivalents. You can
use either standard names or OpenSSL names in cipher lists, or a mix of
both.
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.

Note: these ciphers are purely HMAC based and do not provide any
confidentiality and thus are disabled by default. These ciphers are
only available at security level 0.
"EDH-" aliases to "DHE-" names for backward compatibility
The following names are accepted by older releases:
EDH-RSA-DES-CBC3-SHA - alias of DHE-RSA-DES-CBC3-SHA
EDH-DSS-DES-CBC3-SHA - alias of 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 AES ciphers and then place RSA ciphers last:
openssl ciphers -v 'AES:+RSA'
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'

HISTORY
The -V option was added in OpenSSL 1.0.0.
The -stdname is only available if OpenSSL is built with tracing enabled
(enable-ssl-trace argument to Configure) before OpenSSL 1.1.1.
The -convert option was added in OpenSSL 1.1.1.
Support for standard IANA names in cipher lists was added in OpenSSL
3.2.0.
The support for TLS v1.3 integrity-only cipher suites was added in
OpenSSL 3.4.
