Elocrypt

Elocrypt generates pronounceable, easy-to-remember, hard-to-guess passwords... as hard as Vince Carter's knee cartilage is. Elocrypt includes a Haskell library and program.

Prerequisites

In order to build or install you will need

• GHC (tested on 8.6.5)
• Stack (tested on 2.1.3.1)

Installing

Elocrypt is on Hackage. Installation is as easy as:

cabal install elocrypt

Binaries are also available:

• elocrypt-2.1.0-linux-bin.tar.gz
• elocrypt-2.1.0-osx-bin.exe

Running

Generate a list passwords:

elocrypt [length]

You can also generate random phrases (1 per line):

elocrypt --passphrases [min-length] [max-length]

Obtaining the source

Elocrypt sources can be found

• https://github.com/sgillespie/elocrypt
• https://hackage.haskell.org/package/elocrypt

Building

In order to build or install you will need

• GHC (tested on 8.6.5)
• Haskell Stack (tested on 2.1.3.1)

Build elocrypt:

stack setup
stack build

Then, install (if desired):

stack install

API Documentation

The full API documentation is on hackage @ https://hackage.haskell.org/package/elocrypt/docs. To build the documentation yourself, run

stack haddock

API Examples

You can use elocrypt to generate words in any Haskell code, so long as you have installed elocrypt. Generate a word by using Data.Elocrypt.newPassword

import Data.Elocrypt
...
-- Generate a word of length 10
fooGen :: IO String
fooGen = newPassword 10 `liftM` getStdGen

Alternatively, you can use Data.Elocrypt.mkPassword if you want to complete control of the random monad

import Data.Elocrypt
import Control.Monad.Random
...
-- Generate a word of length 10
fooGen' :: IO String
fooGen' = evalRand (mkPassword 10) `liftM` getStdGen
