174 .IP "\fBcipherlist\fR" 4
175 .IX Item "cipherlist"
176 a cipher list to convert to a cipher preference list. If it is not included
177 then the default cipher list will be used. The format is described below.
178 .SH "CIPHER LIST FORMAT"
179 .IX Header "CIPHER LIST FORMAT"
180 The cipher list consists of one or more \fIcipher strings\fR separated by colons.
181 Commas or spaces are also acceptable separators but colons are normally used.
182 .PP
183 The actual cipher string can take several different forms.
184 .PP
185 It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR.
186 .PP
187 It can represent a list of cipher suites containing a certain algorithm, or
188 cipher suites of a certain type. For example \fB\s-1SHA1\s0\fR represents all ciphers
189 suites using the digest algorithm \s-1SHA1\s0 and \fBSSLv3\fR represents all \s-1SSL\s0 v3
190 algorithms.
191 .PP
192 Lists of cipher suites can be combined in a single cipher string using the
193 \&\fB+\fR character. This is used as a logical \fBand\fR operation. For example
194 \&\fB\s-1SHA1+DES\s0\fR represents all cipher suites containing the \s-1SHA1\s0 \fBand\fR the \s-1DES\s0
195 algorithms.
196 .PP
197 Each cipher string can be optionally preceded by the characters \fB!\fR,
198 \&\fB\-\fR or \fB+\fR.
199 .PP
200 If \fB!\fR is used then the ciphers are permanently deleted from the list.
201 The ciphers deleted can never reappear in the list even if they are
202 explicitly stated.
203 .PP
204 If \fB\-\fR is used then the ciphers are deleted from the list, but some or
205 all of the ciphers can be added again by later options.
206 .PP
207 If \fB+\fR is used then the ciphers are moved to the end of the list. This
208 option doesn't add any new ciphers it just moves matching existing ones.
209 .PP
210 If none of these characters is present then the string is just interpreted
211 as a list of ciphers to be appended to the current preference list. If the
212 list includes any ciphers already present they will be ignored: that is they
213 will not moved to the end of the list.
214 .PP
215 Additionally the cipher string \fB\f(CB@STRENGTH\fB\fR can be used at any point to sort
216 the current cipher list in order of encryption algorithm key length.
