 161 Verbose option. List ciphers with a complete description of
 162 protocol version (SSLv2 or SSLv3; the latter includes \s-1TLS\s0), key exchange,

 164 restrictions and whether the algorithm is classed as an \*(L"export\*(R" cipher.
 165 Note that without the \fB\-v\fR option, ciphers may seem to appear twice

 168 .IP "\fB\-V\fR" 4

 174 .IP "\fB\-ssl2\fR" 4

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