high-level ruby library for encryption

Question

It seems like the most established ones like keyczar, cryptlib and NaCl are not available for Ruby. What are some ruby libraries (or bindings) for a high-level library where decisions about cryptographic primitives have been made for you (no need to generate IVs, CBC vs EBC etc.). I did find ruby-gpgme. There's also libmcrypt which has support for symmetric encryption of streams which is what I am ultimately interested in.

Answer 1

NaCl is now (1.0.0 of the gem was published some days ago) available for Ruby through RbNaCl (which uses libsodium, "portable, cross-compilable, installable, packageable, API-compatible version of NaCl"). There is also krypt.

Answer 2

Why not OpenSSL?

It is part of the standard libary:
