Your master password generator

Cretes a strong master password by selecting random words and inserting special characters into them.

This is based on the ideas expressed in xkcd and Computerphile's discussion on how to pick passwords.

Example use

Three random words

$ ./out/masterpass -f=dict/example

Five random words

$ ./out/masterpass -f=dict/example -w=5

Building

Requires Haskell. Specifically, you need ghc and may need to install extra packages through cabal install.

Use make to build, or see the makefile for the build steps.
