This implementation conforms to RFC 2898, and has been tested using the test vectors in Appendix B of RFC 3962. Note, however, that while those specifications use HMAC-SHA-1, this implementation defaults to HMAC-SHA-256. (SHA-256 provides a longer bit length. In addition, NIST has stated that SHA-1 should be phased out due to concerns over recent cryptanalytic attacks.)

RinRuby is a Ruby library that integrates the R interpreter in Ruby, making R's statistical routines and graphics available within Ruby. The library consists of a single Ruby script that is simple to install and does not require any special compilation or installation of R. Since the library is 100% pure Ruby, it works on a variety of operating systems, Ruby implementations, and versions of R. RinRuby's methods are simple, making for readable code. The {website [rinruby.ddahl.org]}[http://rinruby.ddahl.org] describes RinRuby usage, provides comprehensive documentation, gives several examples, and discusses RinRuby's implementation.
