Initial import of NaCl.

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.

Of course, other libraries already exist for these core operations.
NaCl advances the state of the art by improving security, by improving
usability, and by improving speed.
