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

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

230 This is determined at compile time and is normally

232 When used, this must be the first cipherstring specified.

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

238 .IP "\fB\s-1ALL\s0\fR" 4

268 56 bit export ciphers is empty unless OpenSSL has been explicitly configured
269 with support for experimental ciphers.

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

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

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