OPENSSL-CIPHERS(1ossl) OpenSSL OPENSSL-CIPHERS(1ossl) NAME openssl-ciphers - SSL cipher display and cipher list command SYNOPSIS openssl ciphers [-help] [-s] [-v] [-V] [-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. As of OpenSSL 4.0 the list of TLS 1.3 ciphersuites val and TLS 1.2 ciphers cipherlist are processed case-insensitively. 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 algo- rithms. On a server the list of supported ciphers might also exclude other ci- phers depending on the configured certificates and presence of DH para- meters. If this option is not used then all ciphers that match the cipherlist will be listed. -pskWhen combined with -s includes cipher suites which require PSK. -srpWhen 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 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 for- mat for this list is a simple colon (":") separated list of TLSv1.3 ci- phersuite 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 cipher- suites that have been configured. If it is not included then the de- fault 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-pa- rameters/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 algo- rithms. 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, DE- FAULT+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 de- fault cipher suite list provides strong security and reasonable inter- operability. 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 en- cryption algorithms but excluding export cipher suites. All these ci- pher suites 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 in- cluded 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 ci- pher 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 re- spectively. Note: there are no cipher suites specific to TLS v1.1. Since this is only the minimum version, if, for example, TLSv1.0 is ne- gotiated 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 sup- ported 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 ci- pher 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. 3DESCipher 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. IDEACipher suites using IDEA. SEEDCipher suites using SEED. MD5 Cipher suites using MD5. SHA1, SHA Cipher suites using SHA1. SHA256, SHA384 Cipher suites using SHA256 or SHA384. aGOST Cipher suites using GOST R 34.10 (either 2001 or 2012) for authentica- tion (needs a provider that supports GOST algorithms). aGOST01 Cipher suites that can be uses with GOST R 34.10-2001 keys for authen- tication. aGOST12 Cipher suites that can be used with GOST R 34.10-2012 keys for authen- tication. kGOST Cipher suites using VKO 34.10 key exchange and key wrap specified in the RFC 4357 or RFC 7836. kGOST18 Cipher suites using VKO 34.10 key exchange specified in the RFC 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. GOST89MAC Cipher suites using GOST 28147-89 MAC instead of HMAC with S-boxes A. GOST89MAC12 Cipher suites using GOST 28147-89 MAC instead of HMAC with S-boxes 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. aPSKCipher suites using PSK authentication (currently all PSK modes apart from RSA_PSK). kSRP, SRP Cipher suites using SRP key exchange. aSRPCipher 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 se- curity 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 ear- lier. 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 ei- ther 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 au- thentication used, e.g. DES-CBC3-SHA. In these cases, RSA authentication is used.

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 authenti- cation (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' SEE ALSO openssl(1), openssl-s_client(1), openssl-s_server(1), ssl(7) 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. The list of TLS 1.3 ciphersuites val and TLS 1.2 ciphers cipherlist were case-sensitive prior to OpenSSL 4.0. COPYRIGHT Copyright 2000-2026 The OpenSSL Project Authors. All Rights Reserved.
