<H2>DESCRIPTION</H2>
The <B>ciphers</B> command converts textual OpenSSL cipher lists into ordered
<FONT SIZE="-1">SSL</FONT> cipher preference lists. It can be used as a test tool to determine
the appropriate cipherlist.
<A NAME="lbAE">&nbsp;</A>
<H2>OPTIONS</H2>
<DL COMPACT>
<DT id="1"><B>-help</B><DD>
Print a usage message.
<DT id="2"><B>-s</B><DD>
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.
<P>
<FONT SIZE="-1">PSK</FONT> and <FONT SIZE="-1">SRP</FONT> ciphers are not enabled by default: they require <B>-psk</B> or <B>-srp</B>
to enable them.
<P>
It also does not change the default list of supported signature algorithms.
<P>
On a server the list of supported ciphers might also exclude other ciphers
depending on the configured certificates and presence of <FONT SIZE="-1">DH</FONT> parameters.
<P>
If this option is not used then all ciphers that match the cipherlist will be
listed.
<DT id="3"><B>-psk</B><DD>
When combined with <B>-s</B> includes cipher suites which require <FONT SIZE="-1">PSK.</FONT>
<DT id="4"><B>-srp</B><DD>
When combined with <B>-s</B> includes cipher suites which require <FONT SIZE="-1">SRP.</FONT>
<DT id="5"><B>-v</B><DD>
Verbose output: For each cipher suite, list details as provided by
<B><A HREF="/cgi-bin/man/man2html?3+SSL_CIPHER_description">SSL_CIPHER_description</A></B>(3).
<DT id="6"><B>-V</B><DD>
Like <B>-v</B>, but include the official cipher suite values in hex.
<DT id="7"><B>-tls1_3</B>, <B>-tls1_2</B>, <B>-tls1_1</B>, <B>-tls1</B>, <B>-ssl3</B><DD>
In combination with the <B>-s</B> 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.
<DT id="8"><B>-stdname</B><DD>
Precede each cipher suite by its standard name.
<DT id="9"><B>-convert name</B><DD>
Convert a standard cipher <B>name</B> to its OpenSSL name.
<DT id="10"><B>-ciphersuites val</B><DD>
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:
<P>
<PRE>
TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256:TLS_AES_128_GCM_SHA256
</PRE>
<DT id="11"><B>cipherlist</B><DD>
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.
</DL>
<A NAME="lbAF">&nbsp;</A>
<H2>CIPHER LIST FORMAT</H2>
The cipher list consists of one or more <I>cipher strings</I> separated by colons.
Commas or spaces are also acceptable separators but colons are normally used.
<P>
The actual cipher string can take several different forms.
<P>
It can consist of a single cipher suite such as <B></B><FONT SIZE="-1"><B>RC4-SHA</B></FONT><B></B>.
<P>
It can represent a list of cipher suites containing a certain algorithm, or
cipher suites of a certain type. For example <B></B><FONT SIZE="-1"><B>SHA1</B></FONT><B></B> represents all ciphers
suites using the digest algorithm <FONT SIZE="-1">SHA1</FONT> and <B>SSLv3</B> represents all <FONT SIZE="-1">SSL</FONT> v3
algorithms.
<P>
Lists of cipher suites can be combined in a single cipher string using the
<B>+</B> character. This is used as a logical <B>and</B> operation. For example
<B></B><FONT SIZE="-1"><B>SHA1+DES</B></FONT><B></B> represents all cipher suites containing the <FONT SIZE="-1">SHA1</FONT> <B>and</B> the <FONT SIZE="-1">DES</FONT>
algorithms.
<P>
Each cipher string can be optionally preceded by the characters <B>!</B>,
<B>-</B> or <B>+</B>.
<P>
If <B>!</B> 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.
<P>
If <B>-</B> is used then the ciphers are deleted from the list, but some or
all of the ciphers can be added again by later options.
<P>
If <B>+</B> 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.
<P>
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.
<P>
The cipher string <B></B>@STRENGTH<B></B> can be used at any point to sort the current
cipher list in order of encryption algorithm key length.
<P>
The cipher string <B></B>@SECLEVEL<B>=n</B> can be used at any point to set the security
level to <B>n</B>, which should be a number between zero and five, inclusive.
See SSL_CTX_set_security_level for a description of what each level means.
<P>
The cipher list can be prefixed with the <B></B><FONT SIZE="-1"><B>DEFAULT</B></FONT><B></B> keyword, which enables
the default cipher list as defined below. Unlike cipher strings,
this prefix may not be combined with other strings using <B>+</B> character.
For example, <B></B><FONT SIZE="-1"><B>DEFAULT+DES</B></FONT><B></B> is not valid.
<P>
The content of the default list is determined at compile time and normally
corresponds to <B></B><FONT SIZE="-1"><B>ALL:</B></FONT><B>!COMPLEMENTOFDEFAULT:!eNULL</B>.
<A NAME="lbAG">&nbsp;</A>
<H2>CIPHER STRINGS</H2>
The following is a list of all permitted cipher strings and their meanings.
<DL COMPACT>
<DT id="12"><B></B><FONT SIZE="-1"><B>COMPLEMENTOFDEFAULT</B></FONT><B></B><DD>
The ciphers included in <B></B><FONT SIZE="-1"><B>ALL</B></FONT><B></B>, but not enabled by default. Currently
this includes all <FONT SIZE="-1">RC4</FONT> and anonymous ciphers. Note that this rule does
not cover <B>eNULL</B>, which is not included by <B></B><FONT SIZE="-1"><B>ALL</B></FONT><B></B> (use <B></B><FONT SIZE="-1"><B>COMPLEMENTOFALL</B></FONT><B></B> if
necessary). Note that <FONT SIZE="-1">RC4</FONT> based cipher suites are not built into OpenSSL by
default (see the enable-weak-ssl-ciphers option to Configure).
<DT id="13"><B></B><FONT SIZE="-1"><B>ALL</B></FONT><B></B><DD>
All cipher suites except the <B>eNULL</B> ciphers (which must be explicitly enabled
if needed).
As of OpenSSL 1.0.0, the <B></B><FONT SIZE="-1"><B>ALL</B></FONT><B></B> cipher suites are sensibly ordered by default.
<DT id="14"><B></B><FONT SIZE="-1"><B>COMPLEMENTOFALL</B></FONT><B></B><DD>
The cipher suites not enabled by <B></B><FONT SIZE="-1"><B>ALL</B></FONT><B></B>, currently <B>eNULL</B>.
<DT id="15"><B></B><FONT SIZE="-1"><B>HIGH</B></FONT><B></B><DD>
``High'' encryption cipher suites. This currently means those with key lengths
larger than 128 bits, and some cipher suites with 128-bit keys.
<DT id="16"><B></B><FONT SIZE="-1"><B>MEDIUM</B></FONT><B></B><DD>
``Medium'' encryption cipher suites, currently some of those using 128 bit
encryption.
<DT id="17"><B></B><FONT SIZE="-1"><B>LOW</B></FONT><B></B><DD>
``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.
<DT id="18"><B>eNULL</B>, <B></B><FONT SIZE="-1"><B>NULL</B></FONT><B></B><DD>
The ``<FONT SIZE="-1">NULL''</FONT> 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
<B></B><FONT SIZE="-1"><B>DEFAULT</B></FONT><B></B> or <B></B><FONT SIZE="-1"><B>ALL</B></FONT><B></B> cipher strings.
Be careful when building cipherlists out of lower-level primitives such as
<B>kRSA</B> or <B>aECDSA</B> as these do overlap with the <B>eNULL</B> ciphers. When in
doubt, include <B>!eNULL</B> in your cipherlist.
<DT id="19"><B>aNULL</B><DD>
The cipher suites offering no authentication. This is currently the anonymous
<FONT SIZE="-1">DH</FONT> algorithms and anonymous <FONT SIZE="-1">ECDH</FONT> algorithms. These cipher suites are vulnerable
to ``man in the middle'' attacks and so their use is discouraged.
These are excluded from the <B></B><FONT SIZE="-1"><B>DEFAULT</B></FONT><B></B> ciphers, but included in the <B></B><FONT SIZE="-1"><B>ALL</B></FONT><B></B>
ciphers.
Be careful when building cipherlists out of lower-level primitives such as
<B>kDHE</B> or <B></B><FONT SIZE="-1"><B>AES</B></FONT><B></B> as these do overlap with the <B>aNULL</B> ciphers.
When in doubt, include <B>!aNULL</B> in your cipherlist.
<DT id="20"><B>kRSA</B>, <B>aRSA</B>, <B></B><FONT SIZE="-1"><B>RSA</B></FONT><B></B><DD>
Cipher suites using <FONT SIZE="-1">RSA</FONT> key exchange or authentication. <B></B><FONT SIZE="-1"><B>RSA</B></FONT><B></B> is an alias for
<B>kRSA</B>.
<DT id="21"><B>kDHr</B>, <B>kDHd</B>, <B>kDH</B><DD>
Cipher suites using static <FONT SIZE="-1">DH</FONT> key agreement and <FONT SIZE="-1">DH</FONT> certificates signed by CAs
with <FONT SIZE="-1">RSA</FONT> and <FONT SIZE="-1">DSS</FONT> keys or either respectively.
All these cipher suites have been removed in OpenSSL 1.1.0.
<DT id="22"><B>kDHE</B>, <B>kEDH</B>, <B></B><FONT SIZE="-1"><B>DH</B></FONT><B></B><DD>
Cipher suites using ephemeral <FONT SIZE="-1">DH</FONT> key agreement, including anonymous cipher
suites.
<DT id="23"><B></B><FONT SIZE="-1"><B>DHE</B></FONT><B></B>, <B></B><FONT SIZE="-1"><B>EDH</B></FONT><B></B><DD>
Cipher suites using authenticated ephemeral <FONT SIZE="-1">DH</FONT> key agreement.
<DT id="24"><B></B><FONT SIZE="-1"><B>ADH</B></FONT><B></B><DD>
Anonymous <FONT SIZE="-1">DH</FONT> cipher suites, note that this does not include anonymous Elliptic
Curve <FONT SIZE="-1">DH</FONT> (<FONT SIZE="-1">ECDH</FONT>) cipher suites.
<DT id="25"><B>kEECDH</B>, <B>kECDHE</B>, <B></B><FONT SIZE="-1"><B>ECDH</B></FONT><B></B><DD>
Cipher suites using ephemeral <FONT SIZE="-1">ECDH</FONT> key agreement, including anonymous
cipher suites.
<DT id="26"><B></B><FONT SIZE="-1"><B>ECDHE</B></FONT><B></B>, <B></B><FONT SIZE="-1"><B>EECDH</B></FONT><B></B><DD>
Cipher suites using authenticated ephemeral <FONT SIZE="-1">ECDH</FONT> key agreement.
<DT id="27"><B></B><FONT SIZE="-1"><B>AECDH</B></FONT><B></B><DD>
Anonymous Elliptic Curve Diffie-Hellman cipher suites.
<DT id="28"><B>aDSS</B>, <B></B><FONT SIZE="-1"><B>DSS</B></FONT><B></B><DD>
Cipher suites using <FONT SIZE="-1">DSS</FONT> authentication, i.e. the certificates carry <FONT SIZE="-1">DSS</FONT> keys.
<DT id="29"><B>aDH</B><DD>
Cipher suites effectively using <FONT SIZE="-1">DH</FONT> authentication, i.e. the certificates carry
<FONT SIZE="-1">DH</FONT> keys.
All these cipher suites have been removed in OpenSSL 1.1.0.
<DT id="30"><B>aECDSA</B>, <B></B><FONT SIZE="-1"><B>ECDSA</B></FONT><B></B><DD>
Cipher suites using <FONT SIZE="-1">ECDSA</FONT> authentication, i.e. the certificates carry <FONT SIZE="-1">ECDSA</FONT>
keys.
<DT id="31"><B>TLSv1.2</B>, <B>TLSv1.0</B>, <B>SSLv3</B><DD>
Lists cipher suites which are only supported in at least <FONT SIZE="-1">TLS</FONT> v1.2, <FONT SIZE="-1">TLS</FONT> v1.0 or
<FONT SIZE="-1">SSL</FONT> v3.0 respectively.
Note: there are no cipher suites specific to <FONT SIZE="-1">TLS</FONT> 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.
<P>
Note: these cipher strings <B>do not</B> change the negotiated version of <FONT SIZE="-1">SSL</FONT> or
<FONT SIZE="-1">TLS,</FONT> they only affect the list of available cipher suites.
<DT id="32"><B></B><FONT SIZE="-1"><B>AES128</B></FONT><B></B>, <B></B><FONT SIZE="-1"><B>AES256</B></FONT><B></B>, <B></B><FONT SIZE="-1"><B>AES</B></FONT><B></B><DD>
