crypton-box: NaCl crypto/secret box implementations based on crypton primitives.

[ bsd3, cryptography, library ] [ Propose Tags ] [ Report a vulnerability ]

This library provides a high-level API for authenticated encryption and decryption using the NaCl crypto_box and crypto_secretbox constructs.

The API is implemented in pure Haskell using XSalsa and Poly1305 primitives provided by the crypton library.

Important: This library has not been professionally reviewed. Side channel attacks and memory-related vulnerabilities may exist! Use at your own risk.

(P.S. I would love to hear from you if you can audit this library and improve its security!)

Readme for crypton-box-1.2.0

[back to package description]

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
