Generate passphrases using the wordlists for random passphrases made by the EFF.
By default, generated passphrases consist of twelve words randomly selected from the autocomplete-optimized wordlist. Be sure to read the article to learn about the difference between the wordlists.
pgen [--dice] [-l | -s] [-e] [-n <n>]
pgen -h | --help
-l
Use long wordlist instead of autocomplete-optimized short wordlist.
Recommended for the creation of memorable passphrases since the
increased number of words as well as the greater effective word
length allows for good entropy with a lower amount of words
compared to the autocomplete-optimized short wordlist.
Mutually exclusive with option -s
.
-s
Use non-optimized short wordlist instead of autocomplete-optimized
short wordlist. Mutually exclusive with option -l
.
-e
Print the entropy of the generated passphrase to stderr.
-n
Specify the number of words to use n. Default value:
-s

option was specified).-l

option was specified).--dice
Use physical six-sided dice instead of letting the computer pick
words. Useful in case you distrust the ability or willingness of your
computer to generate "sufficiently random" numbers. Even though pgen
will
do the right thing and use /dev/urandom
by default on Unix platforms [1],
what if the hardware source(s) for the entropy that the /dev/urandom
CSPRNG is collecting is/are rigged? With the --dice
option
you need not worry about that at least. (But have you considered
the risk of undetectable malware? [2], [3])
-h
, --help
Show help and exit.
-V
, --version
Print version information and exit.
Build from source (see the Building section below) and
copy the target/release/pgen
binary into your ~/bin/
