elocrypt-0.4.0: README.md

# Elocrypt
[![Build Status](https://travis-ci.org/sgillespie/elocrypt.svg?branch=master)](https://travis-ci.org/sgillespie/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 7.10 and 7.8)
 * cabal-install (tested on 1.20 and 1.22)

## Installing
Elocrypt is on [Hackage](https://hackage.haskell.org/package/elocrypt).  Installation is as easy as:
```
cabal install elocrypt
```

## Running
Running elocrypt is as simple as:
```
elocrypt [length]
```

## Obtaining the source
Elocrypt sources can be found 
 * https://github.com/sgillespie/elocrypt

## Building
In order to build or install you will need
 * GHC (tested on 7.10 and 7.8)
 * cabal-install (tested on 1.20 and 1.22)

Build elocrypt:
```
cabal configure
cabal build
```
Then, install (if desired):
```
cabal install
```

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