# haskell-crypto-simple

A simple high level encryption interface based on cryptonite

## Usage

```haskell

> import Crypto.Simple.CBC (encrypt, decrypt) 

> import Data.ByteString.Char8 (pack)

> let key = pack "my secret key"

> let msg = pack "this is a message"

> encrypt key msg >>= \secretMsg -> decrypt key secretMsg

"this is a message"

```

## Implementation

The implementation is based on some good defaults

- The cipher that's used is AES 256

- You can choose between CBC or CTR cipher modes (modules Crypto.Simple.CBC and Crypto.Simple.CTR) 

- If you use CBC, it will pad/unpad the message using the PKCS7 padding scheme 

- The entropy method used for the initialization vector is the default system-level CSPRNG (ie. /dev/random). It is based on Crypto.Random.Entropy.getEntropy

- The maximum size for the encryption key is 32 bytes
