Dmp

DMP (or Dice My Pass) is a simple passphrase generator that gives you a passphrase of the desired length using EFF's long wordlist. This little tool was only created for a blog post on how to create a Ruby gem at codingdose.info (WIP) and should be NOT used for production, can't say much if you like it though.

Installation

Add this line to your application's Gemfile:

gem 'dmp'

And then execute:

$ bundle

Or install it yourself as:

$ gem install dmp

Usage

You can use it as a library in your code.

irb(main):001:0> require 'dmp'
=> true
irb(main):002:0> Dmp.gen_passphrase(4)
=> ["discount", "stove", "rubbing", "underage"]

Or you can use the CLI if you want to execute it in the terminal.

Generate a passphrase

$ dmp
- Passphrase: bagpipe sprinkled unscented trespass splice outlet headlamp

Generate a passphrase and copy it to the clipboard

Generate a passphrase of your desired length and check if the password appears in HIBP datasets
