NAME
ciphers - SSL cipher display and cipher list tool.SYNOPSIS
openssl ciphers [-v] [-V] [-ssl2] [-ssl3] [-tls1] [cipherlist]DESCRIPTION
The ciphers command converts textual OpenSSL cipher lists into orderedCOMMAND OPTIONS
- -v
-
Verbose option. List ciphers with a complete description of
protocol version (SSLv2 or SSLv3; the latter includes TLS), key exchange, authentication, encryption and mac algorithms used along with any key size restrictions and whether the algorithm is classed as an ``export'' cipher. Note that without the -v option, ciphers may seem to appear twice in a cipher list; this is when similar ciphers are available forSSLv2 and forSSLv3/TLS v1.
- -V
- Like -v, but include cipher suite codes in output (hex format).
- -ssl3, -tls1
- This lists ciphers compatible with any of SSLv3, TLSv1, TLSv1.1 or TLSv1.2.
- -ssl2
- Only include SSLv2 ciphers.
- -h, -?
- Print a brief usage message.
- 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
It can represent a list of cipher suites containing a certain algorithm, or cipher suites of a certain type. For example
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
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.
Additionally the cipher string @STRENGTH can be used at any point to sort the current cipher list in order of encryption algorithm key length.
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:!EXPORT:!aNULL:!eNULL:!SSLv2. When used, this must be the first cipherstring specified.
- COMPLEMENTOFDEFAULT
-
the ciphers included in ALL, but not enabled by default. Currently this isADHandAECDH. Note that this rule does not cover eNULL, which is not included byALL(useCOMPLEMENTOFALLif necessary).
- ALL
-
all cipher suites except the eNULL ciphers which must be explicitly enabled;
as of OpenSSL, the ALLcipher suites are reasonably ordered by default
- COMPLEMENTOFALL
-
the cipher suites not enabled by ALL, currently being 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 strength encryption cipher suites, currently those using 64 or 56 bit encryption algorithms but excluding export cipher suites. As of OpenSSL 1.0.2g, these are disabled in default builds.
- EXP,EXPORT
- Export strength encryption algorithms. Including 40 and 56 bits algorithms. As of OpenSSL 1.0.2g, these are disabled in default builds.
- EXPORT40
- 40-bit export encryption algorithms As of OpenSSL 1.0.2g, these are disabled in default builds.
- EXPORT56
- 56-bit export encryption algorithms. In OpenSSL 0.9.8c and later the set of 56 bit export ciphers is empty unless OpenSSL has been explicitly configured with support for experimental ciphers. As of OpenSSL 1.0.2g, these are disabled in default builds.
- 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 theDEFAULTorALLcipher 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
DHalgorithms and anonymousECDHalgorithms. These cipher suites are vulnerable to a ``man in the middle'' attack and so their use is normally discouraged. These are excluded from theDEFAULTciphers, but included in theALLciphers. Be careful when building cipherlists out of lower-level primitives such as kDHE orAESas these do overlap with the aNULL ciphers. When in doubt, include !aNULL in your cipherlist.

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 onlyECDSAandSHA256orSHA384,only the elliptic curves P-256 and P-384 can be used and only the two suite B compliant ciphersuites (ECDHE-ECDSA-AES128-GCM-SHA256andECDHE-ECDSA-AES256-GCM-SHA384) are permissible.
