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