139 ciphers \- SSL cipher display and cipher list tool.
141 .IX Header "SYNOPSIS"
142 \&\fBopenssl\fR \fBciphers\fR
150 .IX Header "DESCRIPTION"
151 The \fBciphers\fR command converts textual OpenSSL cipher lists into ordered
152 \&\s-1SSL\s0 cipher preference lists. It can be used as a test tool to determine
153 the appropriate cipherlist.
154 .SH "COMMAND OPTIONS"
155 .IX Header "COMMAND OPTIONS"
158 Verbose option. List ciphers with a complete description of
159 protocol version (SSLv2 or SSLv3; the latter includes \s-1TLS\s0), key exchange,
160 authentication, encryption and mac algorithms used along with any key size
161 restrictions and whether the algorithm is classed as an \*(L"export\*(R" cipher.
162 Note that without the \fB\-v\fR option, ciphers may seem to appear twice
163 in a cipher list; this is when similar ciphers are available for
164 \&\s-1SSL\s0 v2 and for \s-1SSL\s0 v3/TLS v1.
167 Like \fB\-v\fR, but include cipher suite codes in output (hex format).
168 .IP "\fB\-ssl3\fR, \fB\-tls1\fR" 4
169 .IX Item "-ssl3, -tls1"
170 This lists ciphers compatible with any of SSLv3, TLSv1, TLSv1.1 or TLSv1.2.
173 Only include SSLv2 ciphers.
174 .IP "\fB\-h\fR, \fB\-?\fR" 4
176 Print a brief usage message.
177 .IP "\fBcipherlist\fR" 4
178 .IX Item "cipherlist"
179 A cipher list to convert to a cipher preference list. If it is not included
180 then the default cipher list will be used. The format is described below.
181 .SH "CIPHER LIST FORMAT"
182 .IX Header "CIPHER LIST FORMAT"
183 The cipher list consists of one or more \fIcipher strings\fR separated by colons.
184 Commas or spaces are also acceptable separators but colons are normally used.
186 The actual cipher string can take several different forms.
188 It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR.
190 It can represent a list of cipher suites containing a certain algorithm, or
191 cipher suites of a certain type. For example \fB\s-1SHA1\s0\fR represents all ciphers
192 suites using the digest algorithm \s-1SHA1\s0 and \fBSSLv3\fR represents all \s-1SSL\s0 v3
195 Lists of cipher suites can be combined in a single cipher string using the
196 \&\fB+\fR character. This is used as a logical \fBand\fR operation. For example
197 \&\fB\s-1SHA1+DES\s0\fR represents all cipher suites containing the \s-1SHA1 \s0\fBand\fR the \s-1DES\s0
200 Each cipher string can be optionally preceded by the characters \fB!\fR,
201 \&\fB\-\fR or \fB+\fR.
203 If \fB!\fR is used then the ciphers are permanently deleted from the list.
204 The ciphers deleted can never reappear in the list even if they are
207 If \fB\-\fR is used then the ciphers are deleted from the list, but some or
208 all of the ciphers can be added again by later options.
210 If \fB+\fR is used then the ciphers are moved to the end of the list. This
211 option doesn't add any new ciphers it just moves matching existing ones.
213 If none of these characters is present then the string is just interpreted
214 as a list of ciphers to be appended to the current preference list. If the
215 list includes any ciphers already present they will be ignored: that is they
216 will not moved to the end of the list.
218 Additionally the cipher string \fB\f(CB@STRENGTH\fB\fR can be used at any point to sort
219 the current cipher list in order of encryption algorithm key length.

222 The following is a list of all permitted cipher strings and their meanings.
223 .IP "\fB\s-1DEFAULT\s0\fR" 4

231 the ciphers included in \fB\s-1ALL\s0\fR, but not enabled by default. Currently

265 with support for experimental ciphers.

269 The \*(L"\s-1NULL\*(R"\s0 ciphers that is those offering no encryption. Because these offer no
270 encryption at all and are a security risk they are not enabled via either the

272 Be careful when building cipherlists out of lower-level primitives such as

277 The cipher suites offering no authentication. This is currently the anonymous
278 \&\s-1DH\s0 algorithms and anonymous \s-1ECDH\s0 algorithms. These cipher suites are vulnerable
279 to a \*(L"man in the middle\*(R" attack and so their use is normally discouraged.
