=head1 NAME

ciphers - SSL cipher display and cipher list tool.

=head1 SYNOPSIS

B<openssl> B<ciphers>
[B<-v>]
[B<-ssl2>]
[B<-ssl3>]
[B<-tls1>]
[B<cipherlist>]

=head1 DESCRIPTION

The B<cipherlist> command converts 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<-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<-ssl3>

only include SSL v3 ciphers.

=item B<-ssl2>

only include SSL v2 ciphers.

=item B<-tls1>

only include TLS v1 ciphers.

=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.

=back

=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.

Additionally the cipher string B<@STRENGTH> can be used at any point to sort
the current cipher list in order of encryption algorithm key length.

=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 normally
B<ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH>. This must be the first cipher string
specified.

=item B<ALL>

all ciphers suites except the B<eNULL> ciphers which must be explicitly enabled.

=item B<HIGH>

"high" encryption cipher suites. This currently means those with key lengths larger
than 128 bits.

=item B<MEDIUM>

"medium" encryption cipher suites, currently 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>

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.

=head1 NOTES

The non-ephemeral DH modes are currently unimplemented in OpenSSL
because there is no support for DH certificates.

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'

320
657e60fa	321	The non-ephemeral DH modes are currently unimplemented in OpenSSL
64287002 DSH	322	because there is no support for DH certificates.
	323
	324	Some compiled versions of OpenSSL may not include all the ciphers
	325	listed here because some ciphers were excluded at compile time.
	326
	327	=head1 EXAMPLES
	328
	329	Verbose listing of all OpenSSL ciphers including NULL ciphers:
	330
	331	openssl ciphers -v 'ALL:eNULL'
	332
	333	Include all ciphers except NULL and anonymous DH then sort by
	334	strength:
	335
	336	openssl ciphers -v 'ALL:!ADH:@STRENGTH'
	337
	338	Include only 3DES ciphers and then place RSA ciphers last:
	339
	340	openssl ciphers -v '3DES:+RSA'
