| 150 | .SH "DESCRIPTION" |
| 151 | .IX Header "DESCRIPTION" |
| 152 | The \fBcipherlist\fR command converts OpenSSL cipher lists into ordered |
| 153 | \&\s-1SSL\s0 cipher preference lists. It can be used as a test tool to determine |
| 154 | the appropriate cipherlist. |
| 155 | .SH "COMMAND OPTIONS" |
| 156 | .IX Header "COMMAND OPTIONS" |
| 157 | .IP "\fB\-v\fR" 4 |
| 158 | .IX Item "-v" |
| 159 | verbose option. List ciphers with a complete description of |
| 160 | protocol version (SSLv2 or SSLv3; the latter includes \s-1TLS\s0), key exchange, |
| 161 | authentication, encryption and mac algorithms used along with any key size |
| 162 | restrictions and whether the algorithm is classed as an \*(L"export\*(R" cipher. |
| 163 | Note that without the \fB\-v\fR option, ciphers may seem to appear twice |
| 164 | in a cipher list; this is when similar ciphers are available for |
| 165 | \&\s-1SSL\s0 v2 and for \s-1SSL\s0 v3/TLS v1. |
| 166 | .IP "\fB\-ssl3\fR" 4 |
| 167 | .IX Item "-ssl3" |
| 168 | only include \s-1SSL\s0 v3 ciphers. |
| 169 | .IP "\fB\-ssl2\fR" 4 |
| 170 | .IX Item "-ssl2" |
| 171 | only include \s-1SSL\s0 v2 ciphers. |
| 172 | .IP "\fB\-tls1\fR" 4 |
| 173 | .IX Item "-tls1" |
| 174 | only include \s-1TLS\s0 v1 ciphers. |
| 175 | .IP "\fB\-h\fR, \fB\-?\fR" 4 |
| 176 | .IX Item "-h, -?" |
| 177 | print a brief usage message. |
| 178 | .IP "\fBcipherlist\fR" 4 |
| 179 | .IX Item "cipherlist" |
| 180 | a cipher list to convert to a cipher preference list. If it is not included |
| 181 | then the default cipher list will be used. The format is described below. |
| 182 | .SH "CIPHER LIST FORMAT" |
| 183 | .IX Header "CIPHER LIST FORMAT" |
| 184 | The cipher list consists of one or more \fIcipher strings\fR separated by colons. |
| 185 | Commas or spaces are also acceptable separators but colons are normally used. |
| 186 | .PP |
| 187 | The actual cipher string can take several different forms. |
| 188 | .PP |
| 189 | It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR. |
| 190 | .PP |
| 191 | It can represent a list of cipher suites containing a certain algorithm, or |
| 192 | cipher suites of a certain type. For example \fB\s-1SHA1\s0\fR represents all ciphers |
| 193 | suites using the digest algorithm \s-1SHA1\s0 and \fBSSLv3\fR represents all \s-1SSL\s0 v3 |
| 194 | algorithms. |
| 195 | .PP |
| 196 | Lists of cipher suites can be combined in a single cipher string using the |
| 197 | \&\fB+\fR character. This is used as a logical \fBand\fR operation. For example |
| 198 | \&\fB\s-1SHA1+DES\s0\fR represents all cipher suites containing the \s-1SHA1\s0 \fBand\fR the \s-1DES\s0 |
| 199 | algorithms. |
| 200 | .PP |
| 201 | Each cipher string can be optionally preceded by the characters \fB!\fR, |
| 202 | \&\fB\-\fR or \fB+\fR. |
| 203 | .PP |
| 204 | If \fB!\fR is used then the ciphers are permanently deleted from the list. |
| 205 | The ciphers deleted can never reappear in the list even if they are |
| 206 | explicitly stated. |
| 207 | .PP |
| 208 | If \fB\-\fR is used then the ciphers are deleted from the list, but some or |
| 209 | all of the ciphers can be added again by later options. |
| 210 | .PP |
| 211 | If \fB+\fR is used then the ciphers are moved to the end of the list. This |
| 212 | option doesn't add any new ciphers it just moves matching existing ones. |
| 213 | .PP |
| 214 | If none of these characters is present then the string is just interpreted |
| 215 | as a list of ciphers to be appended to the current preference list. If the |
| 216 | list includes any ciphers already present they will be ignored: that is they |
| 217 | will not moved to the end of the list. |
| 218 | .PP |
| 219 | Additionally the cipher string \fB\f(CB@STRENGTH\fB\fR can be used at any point to sort |
| 220 | the current cipher list in order of encryption algorithm key length. |
| 221 | .SH "CIPHER STRINGS" |
| 222 | .IX Header "CIPHER STRINGS" |
| 223 | The following is a list of all permitted cipher strings and their meanings. |
| 224 | .IP "\fB\s-1DEFAULT\s0\fR" 4 |
| 225 | .IX Item "DEFAULT" |
| 226 | the default cipher list. This is determined at compile time and is normally |
| 227 | \&\fB\s-1AES:ALL:\s0!aNULL:!eNULL:+RC4:@STRENGTH\fR. This must be the first cipher string |
| 228 | specified. |
| 229 | .IP "\fB\s-1COMPLEMENTOFDEFAULT\s0\fR" 4 |
| 230 | .IX Item "COMPLEMENTOFDEFAULT" |
| 231 | the ciphers included in \fB\s-1ALL\s0\fR, but not enabled by default. Currently |
| 232 | this is \fB\s-1ADH\s0\fR. Note that this rule does not cover \fBeNULL\fR, which is |
| 233 | not included by \fB\s-1ALL\s0\fR (use \fB\s-1COMPLEMENTOFALL\s0\fR if necessary). |
| 234 | .IP "\fB\s-1ALL\s0\fR" 4 |
| 235 | .IX Item "ALL" |

| 238 | .IX Item "COMPLEMENTOFALL" |
| 239 | the cipher suites not enabled by \fB\s-1ALL\s0\fR, currently being \fBeNULL\fR. |
| 240 | .IP "\fB\s-1HIGH\s0\fR" 4 |
| 241 | .IX Item "HIGH" |
| 242 | \&\*(L"high\*(R" encryption cipher suites. This currently means those with key lengths larger |
| 243 | than 128 bits, and some cipher suites with 128\-bit keys. |
| 244 | .IP "\fB\s-1MEDIUM\s0\fR" 4 |
| 245 | .IX Item "MEDIUM" |

| 260 | 56 bit export ciphers is empty unless OpenSSL has been explicitly configured |
| 261 | with support for experimental ciphers. |
| 262 | .IP "\fBeNULL\fR, \fB\s-1NULL\s0\fR" 4 |
| 263 | .IX Item "eNULL, NULL" |
| 264 | the \*(L"\s-1NULL\s0\*(R" ciphers that is those offering no encryption. Because these offer no |
| 265 | encryption at all and are a security risk they are disabled unless explicitly |
| 266 | included. |
| 267 | .IP "\fBaNULL\fR" 4 |
| 268 | .IX Item "aNULL" |
| 269 | the cipher suites offering no authentication. This is currently the anonymous |
| 270 | \&\s-1DH\s0 algorithms. These cipher suites are vulnerable to a \*(L"man in the middle\*(R" |
| 271 | attack and so their use is normally discouraged. |
| 272 | .IP "\fBkRSA\fR, \fB\s-1RSA\s0\fR" 4 |
