saltine-0.2.2.0: Cryptography that's easy to digest (NaCl/libsodium bindings).

NaCl (pronounced "salt") is a new easy-to-use high-speed software library for network communication, encryption, decryption, signatures, etc. NaCl's goal is to provide all of the core operations needed to build higher-level cryptographic tools.

Sodium is a portable, cross-compilable, installable, packageable crypto library based on NaCl, with a compatible API.

Saltine is a Haskell binding to the NaCl primitives going through Sodium for build convenience and, eventually, portability.
