.SH "DESCRIPTION"
|
|
.IX Header "DESCRIPTION"
|
|
The \fBciphers\fR command converts textual OpenSSL cipher lists into ordered
|
|
\&\s-1SSL\s0 cipher preference lists. It can be used as a test tool to determine
|
|
the appropriate cipherlist.
|
|
.SH "COMMAND OPTIONS"
|
|
.IX Header "COMMAND OPTIONS"
|
|
.IP "\fB\-v\fR" 4
|
|
.IX Item "-v"
|
|
Verbose option. List ciphers with a complete description of
|
|
protocol version (SSLv2 or SSLv3; the latter includes \s-1TLS\s0), key exchange,
|
|
authentication, encryption and mac algorithms used along with any key size
|
|
restrictions and whether the algorithm is classed as an \*(L"export\*(R" cipher.
|
|
Note that without the \fB\-v\fR option, ciphers may seem to appear twice
|
|
in a cipher list; this is when similar ciphers are available for
|
|
\&\s-1SSL\s0 v2 and for \s-1SSL\s0 v3/TLS v1.
|
|
.IP "\fB\-V\fR" 4
|
|
.IX Item "-V"
|
|
Like \fB\-v\fR, but include cipher suite codes in output (hex format).
|
|
.IP "\fB\-ssl3\fR" 4
|
|
.IX Item "-ssl3"
|
|
only include \s-1SSL\s0 v3 ciphers.
|
|
.IP "\fB\-ssl2\fR" 4
|
|
.IX Item "-ssl2"
|
|
only include \s-1SSL\s0 v2 ciphers.
|
|
.IP "\fB\-tls1\fR" 4
|
|
.IX Item "-tls1"
|
|
only include \s-1TLS\s0 v1 ciphers.
|
|
.IP "\fB\-h\fR, \fB\-?\fR" 4
|
|
.IX Item "-h, -?"
|
|
print a brief usage message.
|
|
.IP "\fBcipherlist\fR" 4
|
|
.IX Item "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.
|
|
.SH "CIPHER LIST FORMAT"
|
|
.IX Header "CIPHER LIST FORMAT"
|
|
The cipher list consists of one or more \fIcipher strings\fR separated by colons.
|
|
Commas or spaces are also acceptable separators but colons are normally used.
|
|
.PP
|
|
The actual cipher string can take several different forms.
|
|
.PP
|
|
It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR.
|
|
.PP
|
|
It can represent a list of cipher suites containing a certain algorithm, or
|
|
cipher suites of a certain type. For example \fB\s-1SHA1\s0\fR represents all ciphers
|
|
suites using the digest algorithm \s-1SHA1\s0 and \fBSSLv3\fR represents all \s-1SSL\s0 v3
|
|
algorithms.
|
|
.PP
|
|
Lists of cipher suites can be combined in a single cipher string using the
|
|
\&\fB+\fR character. This is used as a logical \fBand\fR operation. For example
|
|
\&\fB\s-1SHA1+DES\s0\fR represents all cipher suites containing the \s-1SHA1 \s0\fBand\fR the \s-1DES\s0
|
|
algorithms.
|
|
.PP
|
|
Each cipher string can be optionally preceded by the characters \fB!\fR,
|
|
\&\fB\-\fR or \fB+\fR.
|
|
.PP
|
|
If \fB!\fR 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.
|
|
.PP
|
|
If \fB\-\fR is used then the ciphers are deleted from the list, but some or
|
|
all of the ciphers can be added again by later options.
|
|
.PP
|
|
If \fB+\fR 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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
Additionally the cipher string \fB\f(CB@STRENGTH\fB\fR can be used at any point to sort
|
|
the current cipher list in order of encryption algorithm key length.
|
|
.SH "CIPHER STRINGS"
|
|
.IX Header "CIPHER STRINGS"
|
|
The following is a list of all permitted cipher strings and their meanings.
|
|
.IP "\fB\s-1DEFAULT\s0\fR" 4
|
|
.IX Item "DEFAULT"
|
|
the default cipher list. This is determined at compile time and
|
|
is normally \fB\s-1ALL:\s0!EXPORT:!aNULL:!eNULL:!SSLv2\fR. This must be the firstcipher string
|
|
specified.
|
|
.IP "\fB\s-1COMPLEMENTOFDEFAULT\s0\fR" 4
|
|
.IX Item "COMPLEMENTOFDEFAULT"
|
|
the ciphers included in \fB\s-1ALL\s0\fR, but not enabled by default. Currently
|
|
this is \fB\s-1ADH\s0\fR and \fB\s-1AECDH\s0\fR. Note that this rule does not cover \fBeNULL\fR,
|
|
which is not included by \fB\s-1ALL\s0\fR (use \fB\s-1COMPLEMENTOFALL\s0\fR if necessary).
|
|
.IP "\fB\s-1ALL\s0\fR" 4
|
|
.IX Item "ALL"
|
|
all cipher suites except the \fBeNULL\fR ciphers which must be explicitly enabled;
|
|
as of OpenSSL, the \fB\s-1ALL\s0\fR cipher suites are reasonably ordered by default
|
|
.IP "\fB\s-1COMPLEMENTOFALL\s0\fR" 4
|
|
.IX Item "COMPLEMENTOFALL"
|
|
the cipher suites not enabled by \fB\s-1ALL\s0\fR, currently being \fBeNULL\fR.
|
|
.IP "\fB\s-1HIGH\s0\fR" 4
|
|
.IX Item "HIGH"
|
|
\&\*(L"high\*(R" encryption cipher suites. This currently means those with key lengths larger
|
|
than 128 bits, and some cipher suites with 128\-bit keys.
|
|
.IP "\fB\s-1MEDIUM\s0\fR" 4
|
|
.IX Item "MEDIUM"
|
|
\&\*(L"medium\*(R" encryption cipher suites, currently some of those using 128 bit encryption.
|
|
.IP "\fB\s-1LOW\s0\fR" 4
|
|
.IX Item "LOW"
|
|
\&\*(L"low\*(R" encryption cipher suites, currently those using 64 or 56 bit encryption algorithms
|
|
but excluding export cipher suites.
|
|
.IP "\fB\s-1EXP\s0\fR, \fB\s-1EXPORT\s0\fR" 4
|

|
|
.IP "\fB\s-1EXPORT56\s0\fR" 4
|
|
.IX Item "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.
|
|
.IP "\fBeNULL\fR, \fB\s-1NULL\s0\fR" 4
|
|
.IX Item "eNULL, NULL"
|
|
the \*(L"\s-1NULL\*(R"\s0 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.
|
|
.IP "\fBaNULL\fR" 4
|
|
.IX Item "aNULL"
|
|
the cipher suites offering no authentication. This is currently the anonymous
|
|
\&\s-1DH\s0 algorithms and anonymous \s-1ECDH\s0 algorithms. These cipher suites are vulnerable
|
|
to a \*(L"man in the middle\*(R" attack and so their use is normally discouraged.

relevant specification and their OpenSSL equivalents. It should be noted,

that several cipher suite names do not include the authentication used,

e.g. \s-1DES\-CBC3\-SHA.\s0 In these cases, \s-1RSA\s0 authentication is used.

The non-ephemeral \s-1DH\s0 modes are currently unimplemented in OpenSSL
|
|
because there is no support for \s-1DH\s0 certificates.

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

The \fB\s-1COMPLENTOFALL\s0\fR and \fB\s-1COMPLEMENTOFDEFAULT\s0\fR selection options
|
|
for cipherlist strings were added in OpenSSL 0.9.7.
|
|
The \fB\-V\fR option for the \fBciphers\fR command was added in OpenSSL 1.0.0.
