[ANN] RbNaCl 3.1.0: a modern cryptography for Ruby: now with scrypt

Happy Friday everyone!

RbNaCl is a Ruby FFI binding to the Networking and Cryptography Library by
Dan Bernstein and his collaborators:

If you're interested in finding out more about it, please check out the
RubyConf talk "Being Boring: A Survivor's Guide to Ruby Cryptography":

Version 3.1.0 includes the scrypt sequential memory-hard password hashing
function, a.k.a. one of the best password hashing functions presently
available. Unlike most other password hashing functions, scrypt introduces
a memory cost which makes its password hashes harder to crack.

Together with libsodium, RbNaCl provides one of the most cross-platform and
cross-VM ways to add scrypt to your Ruby code. RbNaCl supports JRuby too!

Don't want to install libsodium as a dependency? Use the rbnacl-libsodium
gem, which vendors and compiles libsodium for you:
