Cryptography (describes RbNaCl):
RbNaCl is a Ruby FFI binding to the Networking and Cryptography Library
Dan Bernstein and his collaborators:
Version 3.0 includes a new “SimpleBox” API designed to be the most
straightforward API for cryptography possible. It automatically uses a
random nonce per message (using libsodium’s randombytes implementation
which pulls from /dev/urandom on *IX and CryptGenRandom on Windows).
Simplebox is usable for both public-key and secret-key cryptography:
Full list of changes from 2.0 below:
- Rename RandomNonceBox to SimpleBox (backwards compatibility preserved)
- Reverse documented order of SimpleBox/RandomNonceBox initialize
parameters. Technically backwards compatible, but confusing.
- Ensure all strings are ASCII-8BIT/BINARY encoding prior to use
