crypton-box

crypton-box is a Haskell library that provides NaCl's box and secretbox operations, using primitives provided in crypton.

Important: This library is provided as a proof of concept. Please carefully evaluate the security related to your requirements before using! No professional security review has taken place for the implementations, and I strongly recommended not to use this library for anything critical.

Usage

Qualified imports are recommended for use:

import qualified Crypto.PubKey.Curve25519 as X25519
import qualified Crypto.Box as Box

message, nonce :: B.ByteString
secret :: X25519.DhSecret

encrypted :: B.ByteString
encrypted = Box.create message nonce secret

decrypted :: B.ByteString
decrypted = Box.open encrypted nonce secret
