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. http://nacl.cr.yp.to/ Sodium is a portable, cross-compilable, installable, packageable crypto library based on NaCl, with a compatible API. https://github.com/jedisct1/libsodium Saltine is a Haskell binding to the NaCl primitives going through Sodium for build convenience and, eventually, portability.
