[\fB\-v\fR]
[\fB\-V\fR]
[\fB\-ssl2\fR]
[\fB\-ssl3\fR]
[\fB\-tls1\fR]
[\fBcipherlist\fR]
.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, as of OpenSSL
1.0.0, is normally \fB\s-1ALL:\s0!aNULL:!eNULL\fR. This must be the first cipher 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. 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
.IX Item "EXP, EXPORT"
export encryption algorithms. Including 40 and 56 bits algorithms.
.IP "\fB\s-1EXPORT40\s0\fR" 4
.IX Item "EXPORT40"
40 bit export encryption algorithms
.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. These cipher suites are vulnerable to a \*(L"man in the middle\*(R"
attack and so their use is normally discouraged.
.IP "\fBkRSA\fR, \fB\s-1RSA\s0\fR" 4
.IX Item "kRSA, RSA"
cipher suites using \s-1RSA\s0 key exchange.
.IP "\fBkEDH\fR" 4

and \s-1DSS\s0 keys respectively. Not implemented.
.IP "\fBaRSA\fR" 4
.IX Item "aRSA"

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