[ANN] Easy Ruby encryption with RandomNonceBox

[Tony Arcieri]

Hi RbNaClers and Rubyists alike!

Some of you my have tried using RbNaCl and found it confusing. I've just written some documentation for RandomNonceBox, which is the main API I think most people should be using:

https://github.com/cryptosphere/rbnacl/wiki/RandomNonceBox

This is an "omakase" or "Cryptography on Rails" API where all of the hard decisions about cryptography have been made in advance. Most of them have not been made by amateurs but by professional cryptographers.

We think this is probably the best and possibly only truly secure API for Ruby cryptography which covers most of the known attacks. Rails' ActiveSupport::MessageEncryptor comes close, but only in Rails 4+ as previous versions have a known problem (reuse of the same key for encryption and authentication)
