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

 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

 164 .IP "\fB\-V\fR" 4

 170 .IP "\fB\-ssl2\fR" 4

 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.
 184 .PP
 185 The actual cipher string can take several different forms.
 186 .PP
 187 It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR.
 188 .PP
 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
 192 algorithms.
 193 .PP
 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
 197 algorithms.
 198 .PP
 199 Each cipher string can be optionally preceded by the characters \fB!\fR,
 200 \&\fB\-\fR or \fB+\fR.
 201 .PP
 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
 204 explicitly stated.
 205 .PP
 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.
 208 .PP
 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.
 211 .PP
 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.
 216 .PP
 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.
