Passfn

passfn provides a CLI command to generate a password from a domain and a master passphrase.

Caveat

I'm not a security professional.

Installation

Add this line to your application's Gemfile:

gem 'passfn'

And then execute:

$ bundle

Or install it yourself as:

$ gem install passfn

Usage

Assume the master passphrase is:

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Without any options

$ passfn
domain? example.com
passphrase? 
[zB#S2^xBT;@q%.X??ec5s"&?5\%IKaN

With domain option

$ passfn --domain=example.com
passphrase? 
[zB#S2^xBT;@q%.X??ec5s"&?5\%IKaN

Copy to clipboard

$ passfn --domain=example.com --copy
passphrase? 
password for example.com is copied into clipboard
$ pbpaste # I'm using Mac OSX
[zB#S2^xBT;@q%.X??ec5s"&?5\%IKaN
