If something was "present in all versions" of SSLeay, or if it was added to a version of SSLeay (and therefore predates OpenSSL), remove mention of it. Documentation history now starts with OpenSSL. Remove mention of all history before OpenSSL 0.9.8, inclusive. Remove all AUTHOR sections. Reviewed-by: Tim Hudson <tjh@openssl.org>

=head1 NAME
|
|
|
|
ciphers - SSL cipher display and cipher list tool.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<openssl> B<ciphers>
|
|
[B<-s>]
|
|
[B<-v>]
|
|
[B<-V>]
|
|
[B<-ssl3>]
|
|
[B<-tls1>]

|
[B<-stdname>]
|

|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<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.
|
|
|
|
=head1 COMMAND OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-s>
|
|
|
|
Only list supported ciphers: those consistent with the security level. This
|
|
is the actual cipher list an application will support. If this option is
|
|
not used then ciphers excluded by the security level will still be listed.
|
|
|
|
=item B<-v>
|
|
|
|
Verbose option. List ciphers with a complete description of
|
|
protocol version, key exchange,
|
|
authentication, encryption and mac algorithms used along with any key size
|
|
restrictions and whether the algorithm is classed as an "export" cipher.
|
|
|
|
=item B<-V>
|
|
|
|
Like B<-v>, but include cipher suite codes in output (hex format).
|
|
|
|
=item B<-ssl3>
|
|
|
|
only include SSL v3 ciphers.
|
|
|
|
=item B<-tls1>
|
|
|
|
only include TLS v1 ciphers.
|
|
|
|
=item B<-stdname>
|
|
|
|
precede each ciphersuite by its standard name: only available is OpenSSL
|
|
is built with tracing enabled (B<enable-ssl-trace> argument to Configure).
|
|
|
|
=item B<-h>, B<-?>
|
|
|
|
print a brief usage message.
|
|
|
|
=item B<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.
|
|
|
|

|
|
|
|
=head1 CIPHER LIST FORMAT
|
|
|
|
The cipher list consists of one or more I<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 B<RC4-SHA>.
|
|
|
|
It can represent a list of cipher suites containing a certain algorithm, or
|
|
cipher suites of a certain type. For example B<SHA1> represents all ciphers
|
|
suites using the digest algorithm SHA1 and B<SSLv3> represents all SSL v3
|
|
algorithms.
|
|
|
|
Lists of cipher suites can be combined in a single cipher string using the
|
|
B<+> character. This is used as a logical B<and> operation. For example
|
|
B<SHA1+DES> represents all cipher suites containing the SHA1 B<and> the DES
|
|
algorithms.
|
|
|
|
Each cipher string can be optionally preceded by the characters B<!>,
|
|
B<-> or B<+>.
|
|
|
|
If 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.
|
|
|
|
If 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.
|
|
|
|
If 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.
|
|
|
|
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 B<@STRENGTH> can be used at any point to sort the current
|
|
cipher list in order of encryption algorithm key length.
|
|
|
|
The cipher string B<@SECLEVEL=n> can be used at any point to set the security
|
|
level to B<n>.
|
|
|
|
=head1 CIPHER STRINGS
|
|
|
|
The following is a list of all permitted cipher strings and their meanings.
|
|
|
|
=over 4
|
|
|
|
=item B<DEFAULT>
|
|
|
|
the default cipher list. This is determined at compile time and
|
|
is B<ALL:!COMPLEMENTOFDEFAULT:!eNULL>. This must be the first cipher
|
|
string specified.
|
|
|
|
=item B<COMPLEMENTOFDEFAULT>
|
|
|
|
the ciphers included in B<ALL>, but not enabled by default. Currently
|
|
this includes all RC4, DES, RC2 and anonymous ciphers. Note that this rule does
|
|
not cover B<eNULL>, which is not included by B<ALL> (use B<COMPLEMENTOFALL> if
|
|
necessary).
|
|
|
|
=item B<ALL>
|
|
|
|
all cipher suites except the B<eNULL> ciphers which must be explicitly enabled;
|
|
as of OpenSSL, the B<ALL> cipher suites are reasonably ordered by default
|
|
|
|
=item B<COMPLEMENTOFALL>
|
|
|
|
the cipher suites not enabled by B<ALL>, currently being B<eNULL>.
|
|
|
|
=item B<HIGH>
|
|
|
|
"high" encryption cipher suites. This currently means those with key lengths
|
|
larger than 128 bits, and some cipher suites with 128-bit keys.
|
|
|
|
=item B<MEDIUM>
|
|
|
|
"medium" encryption cipher suites, currently some of those using 128 bit
|
|
encryption.
|
|
|
|
=item B<LOW>
|
|
|
|
"low" encryption cipher suites, currently those using 64 or 56 bit encryption
|
|
algorithms but excluding export cipher suites.
|
|
|
|
=item B<EXP>, B<EXPORT>
|
|
|
|
export encryption algorithms. Including 40 and 56 bits algorithms.

|
|
|
|
=item B<eNULL>, B<NULL>

encryption at all and are a security risk they are disabled unless explicitly
|
|
included.
|
|
|
|
=item B<aNULL>
|
|
|
|
the cipher suites offering no authentication. This is currently the anonymous

|
|
(needs an engine supporting GOST algorithms).
|
|
|
|
=item B<aGOST01>
|
|
|
|
cipher suites using GOST R 34.10-2001 authentication.
|
|
|
|
=item B<kGOST>
|
|
|

|
|
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 ciphersuites (ECDHE-ECDSA-AES128-GCM-SHA256 and
|
|
ECDHE-ECDSA-AES256-GCM-SHA384) are permissible.

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.

=head1 NOTES
|
|
|
|
Some compiled versions of OpenSSL may not include all the ciphers
|
|
listed here because some ciphers were excluded at compile time.
|
|
|
|
=head1 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'
