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

221 The following is a list of all permitted cipher strings and their meanings.

277 \&\s-1DH\s0 algorithms and anonymous \s-1ECDH\s0 algorithms. These cipher suites are vulnerable
