180a cipher list to convert to a cipher preference list. If it is not included
181then the default cipher list will be used. The format is described below.
182.SH "CIPHER LIST FORMAT"
8b0cefbb 183.IX Header "CIPHER LIST FORMAT"
984263bc
MD
184The cipher list consists of one or more \fIcipher strings\fR separated by colons.
185Commas or spaces are also acceptable separators but colons are normally used.
186.PP
187The actual cipher string can take several different forms.
188.PP
8b0cefbb 189It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR.
984263bc
MD
190.PP
191It can represent a list of cipher suites containing a certain algorithm, or
8b0cefbb
JR
192cipher suites of a certain type. For example \fB\s-1SHA1\s0\fR represents all ciphers
193suites using the digest algorithm \s-1SHA1\s0 and \fBSSLv3\fR represents all \s-1SSL\s0 v3
984263bc
MD
194algorithms.
195.PP
196Lists of cipher suites can be combined in a single cipher string using the
8b0cefbb
JR
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
984263bc
MD
199algorithms.
200.PP
201Each cipher string can be optionally preceded by the characters \fB!\fR,
8b0cefbb 202\&\fB\-\fR or \fB+\fR.
984263bc
MD
203.PP
204If \fB!\fR is used then the ciphers are permanently deleted from the list.
205The ciphers deleted can never reappear in the list even if they are
206explicitly stated.
207.PP
e3cdf75b 208If \fB\-\fR is used then the ciphers are deleted from the list, but some or
984263bc
MD
209all of the ciphers can be added again by later options.
210.PP
211If \fB+\fR is used then the ciphers are moved to the end of the list. This
212option doesn't add any new ciphers it just moves matching existing ones.
213.PP
214If none of these characters is present then the string is just interpreted
215as a list of ciphers to be appended to the current preference list. If the
216list includes any ciphers already present they will be ignored: that is they
217will not moved to the end of the list.
218.PP
e257b235 219Additionally the cipher string \fB\f(CB@STRENGTH\fB\fR can be used at any point to sort
984263bc
MD
220the current cipher list in order of encryption algorithm key length.
