NAME
       openssl-ciphers,	ciphers	- SSL cipher display and cipher	list tool

SYNOPSIS
       openssl ciphers [-help] [-s] [-v] [-V] [-ssl3] [-tls1] [-tls1_1]
       [-tls1_2] [-tls1_3] [-s]	[-psk] [-srp] [-stdname] [-convert name]
       [-ciphersuites val] [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 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 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, which should be a number between zero and five,
       inclusive.  See SSL_CTX_set_security_level 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+DES 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 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 cipher suites
	   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 cipher	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 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 cipher	suites which are only supported	in at least 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, ARIA
	   Cipher suites using 128 bit ARIA, 256 bit ARIA or 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
	   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
	   Cipher suites 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 cipher suites (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'

HISTORY
       The -V option for the ciphers command 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 was	added in OpenSSL 1.1.1.
