.SH "DESCRIPTION"
|
|
.IX Header "DESCRIPTION"
|
|
dicepwgen generates a diceware password using a dictionary
|
|
file. By default it uses pseudo random dice tosses, but
|
|
it is also possible to use real dices and enter the numbers
|
|
by using the option \fB\-t\fR, which is the most secure way
|
|
to generate diceware passwords.
|
|
.PP
|
|
The option \fB\-c\fR can be used to tweak the number of words
|
|
to output. The options \fB\-l\fR and \fB\-m\fR can be used to tweak
|
|
minimum and maximum word length.
|
|
.PP
|
|
You can tell dicepwgen to use another dictionary file with
|
|
the option \fB\-f\fR.
|
|
.PP
|
|
If you're using a precomputed diceware list, use the parameter
|
|
\&\fB\-n\fR, in which case dicepwgen will use all entries in the file.
|
|
.PP
|
|
The program only uses words which contain 7bit \s-1ASCII\s0 letters
|
|
(a\-zA\-Z0\-9), which are easier for password usage anyway.
|
|
.SH "FILES"
|
|
.IX Header "FILES"
|
|
\&\fB/usr/share/dict/american\-english\fR: default dictionary file.
|
|
.PP
|
|
You can use almost any dictionary file you want. Dicepwgen expects
|
|
the file to be in the following format: one word per line.
|
|
.PP
|
|
You can also use precomputed diceware word lists by adding the
|
|
option \fB\-n\fR to the commandline. If the file already contains
|
|
numbers, you have to remove them before using. Say, the file
|
|
looks like this:
|
|
.PP
|
|
.Vb 4
|
|
\& 11126 abase
|
|
\& 11131 abash
|
|
\& 11132 abate
|
|
\& 11133 abbas
|
|
.Ve
|
|
.PP
|
|
Prepare the file with this shell oneliner:
|
|
.PP
|
|
.Vb 1
|
|
\& grep "^[0\-9]" dicewarelist.txt | awk \*(Aq{print $2}\*(Aq >> newlist.txt

Current known issues:
|
|
.IP "\(bu" 4
|
|
The program does not count the lines in a dictionary file before
|
|
using it. If the file contains a low number of entries (e.g. because
|
|
it is a precomputed diceware word list and \fB\-n\fR has not been
|
|
specified), it seems to \*(L"hang\*(R". In fact it runs very long because it
|
|
jumps over a random number of entries and restarts from the beginning
|
|
again and again til the required number of words has been collected (7776).
