passphrase

This repo contains Crystal and Ruby programs that generate a passphrase using the Diceware algorithm.

Several word lists are available:

EFF long word list (default)
Original Diceware word list
Beale word list
EFF first short list
EFF second short list

The source for these word lists is here.

Crystal Installation

Run this command to build the Crystal version of passphrase:

make

Run this command to install the binary in /usr/local/bin and the word lists in /usr/local/share/passphrase:

make install

Ruby Installation

If you do not have a Crystal compiler, you can use the Ruby version of passphrase. To install it and the word lists, use this command:

make install-ruby

Usage

With no arguments, passphrase prints a 6-word passphrase using the EFF long word list.

For additional usage information, use this command:

passphrase --help

Here is the output of that command:
