=head1 NAME
|
|
|
|
ciphers - SSL cipher display and cipher list tool.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<openssl> B<ciphers>
|
|
[B<-s>]
|
|
[B<-v>]
|
|
[B<-V>]
|
|
[B<-ssl2>]
|
|
[B<-ssl3>]
|
|
[B<-tls1>]
|
|
[B<-stdname>]
|
|
[B<cipherlist>]
|
|
|
|
=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 (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 B<-v> option, ciphers may seem to appear twice
|
|
in a cipher list; this is when similar ciphers are available for
|
|
SSL v2 and for SSL v3/TLS v1.
|
|
|
|
=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<-ssl2>
|
|
|
|
only include SSL v2 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, as of OpenSSL
|
|
1.0.0, is normally B<ALL:!aNULL:!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 is B<ADH>. 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<EXPORT40>
|
|
|
|
40 bit export encryption algorithms
|
|
|
|
=item B<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.
|
|
|
|
=item B<eNULL>, B<NULL>
|
|
|
|
the "NULL" ciphers that is those offering no encryption. Because these offer no
|
|
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
|
|
DH algorithms. These cipher suites are vulnerable to a "man in the middle"
|
|
attack and so their use is normally discouraged.
|
|
|
|
=item B<kRSA>, B<aRSA>, B<RSA>
|
|
|
|
cipher suites using RSA key exchange, authentication or either respectively.
|

|
|
cipher suites using DSS authentication, i.e. the certificates carry DSS keys.

|
|
|
=item B<aDH>
|

|
|
DH keys.

|
|
|

|
|
|
|

|
|
|
|
=item B<aGOST>
|
|
|
|
cipher suites using GOST R 34.10 (either 2001 or 94) for authenticaction
|
|
(needs an engine supporting GOST algorithms).
|
|
|
|
=item B<aGOST01>
|
|
|
|
cipher suites using GOST R 34.10-2001 authentication.
|
|
|
|
=item B<aGOST94>
|
|
|
|
cipher suites using GOST R 34.10-94 authentication (note that R 34.10-94

enables suite B mode 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 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,
|

=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 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 chiphers 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 -v 'ALL:@SECLEVEL=2'
