openssl-ciphers - SSL cipher display and cipher list command
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]
This command converts textual OpenSSL cipher lists into ordered SSL cipher preference lists. It can be used to determine the appropriate cipherlist.
Print a usage message.
See "Provider Options" in openssl(1), provider(7), and property(7).
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.
When combined with -s includes cipher suites which require PSK.
When combined with -s includes cipher suites which require SRP. This option is deprecated.
Verbose output: For each cipher suite, list details as provided by SSL_CIPHER_description(3).
Like -v, but include the official cipher suite values in hex.
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.
Precede each cipher suite by its standard name.
Convert a standard cipher name to its OpenSSL name.
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_SHA256A 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.
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.
The following is a list of all permitted cipher strings and their meanings.
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 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.
The cipher suites not enabled by ALL, currently eNULL.
"High" encryption cipher suites. This currently means those with key lengths larger than 128 bits, and some cipher suites with 128-bit keys.
"Medium" encryption cipher suites, currently some of those using 128 bit encryption.
"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.
Cipher suites permitted in FIPS mode.
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.
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.
Cipher suites using RSA key exchange, RSA authentication, or both of them respectively.
Cipher suites using ephemeral DH key agreement, including anonymous cipher suites.
Cipher suites using authenticated ephemeral DH key agreement.
Anonymous DH cipher suites, note that this does not include anonymous Elliptic Curve DH (ECDH) cipher suites.
Cipher suites using ephemeral ECDH key agreement, including anonymous cipher suites.
Cipher suites using authenticated ephemeral ECDH key agreement.
Anonymous Elliptic Curve Diffie-Hellman cipher suites.
Cipher suites using DSS authentication, i.e. the certificates carry DSS keys.
Cipher suites using ECDSA authentication, i.e. the certificates carry ECDSA keys.
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.
cipher suites using 128 bit AES, 256 bit AES or either 128 or 256 bit AES.
AES in Galois Counter Mode (GCM): these cipher suites are only supported in TLS v1.2.
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.
Cipher suites using 128 bit ARIA or 256 bit ARIA respectively.
Cipher suites using either 128 or 256 bit ARIA.
Cipher suites using 128 bit CAMELLIA, 256 bit CAMELLIA or either 128 or 256 bit CAMELLIA.
Cipher suites using ChaCha20.
Cipher suites using triple DES.
Cipher suites using DES (not triple DES). All these cipher suites have been removed in OpenSSL 1.1.0.
Cipher suites using RC4.
Cipher suites using RC2.
Cipher suites using IDEA.
Cipher suites using SEED.
Cipher suites using MD5.
Cipher suites using SHA1.
Cipher suites using SHA256 or SHA384.
Cipher suites using GOST R 34.10 (either 2001 or 2012) for authentication (needs an engine supporting GOST algorithms).
Cipher suites that can be uses with GOST R 34.10-2001 keys for authentication.
Cipher suites that can be used with GOST R 34.10-2012 keys for authentication.
Cipher suites using VKO 34.10 key exchange and key wrap specified in the RFC 4357 or RFC 7836.
Cipher suites using VKO 34.10 key exchange specified in the RFC 7836 and KExp15 key export specified in the RFC 9189.

Cipher suites, using HMAC based on GOST R 34.11-2012 256 bits.
Cipher suites using GOST 28147-89 MAC instead of HMAC with S-boxes A.
Cipher suites using GOST 28147-89 MAC instead of HMAC with S-boxes Z.
Cipher suites using any GOST cipher (GOST 28147-89, Magma or Kuznyechik).
All cipher suites using pre-shared keys (PSK).
Cipher suites using PSK key exchange, ECDHE_PSK, DHE_PSK or RSA_PSK.
Cipher suites using PSK authentication (currently all PSK modes apart from RSA_PSK).
Cipher suites using SRP key exchange.
Cipher suites using SRP authentication.
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.
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.
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.

TLS_SHA384_SHA384 TLS_SHA384_SHA384Note: 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.
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-SHASome compiled versions of OpenSSL may not include all the ciphers listed here because some ciphers were excluded at compile time.
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'openssl(1), openssl-s_client(1), openssl-s_server(1), ssl(7)
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.
