176a cipher list to convert to a cipher preference list. If it is not included
177then the default cipher list will be used. The format is described below.
178.SH "CIPHER LIST FORMAT"
8b0cefbb 179.IX Header "CIPHER LIST FORMAT"
984263bc
MD
180The cipher list consists of one or more \fIcipher strings\fR separated by colons.
181Commas or spaces are also acceptable separators but colons are normally used.
182.PP
183The actual cipher string can take several different forms.
184.PP
8b0cefbb 185It can consist of a single cipher suite such as \fB\s-1RC4\-SHA\s0\fR.
984263bc
MD
186.PP
187It can represent a list of cipher suites containing a certain algorithm, or
8b0cefbb
JR
188cipher suites of a certain type. For example \fB\s-1SHA1\s0\fR represents all ciphers
189suites using the digest algorithm \s-1SHA1\s0 and \fBSSLv3\fR represents all \s-1SSL\s0 v3
984263bc
MD
190algorithms.
191.PP
192Lists of cipher suites can be combined in a single cipher string using the
8b0cefbb
JR
193\&\fB+\fR character. This is used as a logical \fBand\fR operation. For example
194\&\fB\s-1SHA1+DES\s0\fR represents all cipher suites containing the \s-1SHA1\s0 \fBand\fR the \s-1DES\s0
984263bc
MD
195algorithms.
196.PP
197Each cipher string can be optionally preceded by the characters \fB!\fR,
8b0cefbb 198\&\fB\-\fR or \fB+\fR.
984263bc
MD
199.PP
200If \fB!\fR is used then the ciphers are permanently deleted from the list.
201The ciphers deleted can never reappear in the list even if they are
202explicitly stated.
203.PP
e3cdf75b 204If \fB\-\fR is used then the ciphers are deleted from the list, but some or
984263bc
MD
205all of the ciphers can be added again by later options.
206.PP
207If \fB+\fR is used then the ciphers are moved to the end of the list. This
208option doesn't add any new ciphers it just moves matching existing ones.
209.PP
210If none of these characters is present then the string is just interpreted
211as a list of ciphers to be appended to the current preference list. If the
212list includes any ciphers already present they will be ignored: that is they
213will not moved to the end of the list.
214.PP
e257b235 215Additionally the cipher string \fB\f(CB@STRENGTH\fB\fR can be used at any point to sort
984263bc
MD
216the current cipher list in order of encryption algorithm key length.
