.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
.Ve

or to submit a patch, please open an issue on github:

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).
