The goal of krypt is to provide a platform- and library-independent cryptography API for the Ruby language (www.ruby-lang.org). It can be used with all C(++)-based Ruby implementations as well as JRuby.
The major part of krypt is implemented in Ruby, and it additionally offers the possibility to integrate OS- or language-specific native libraries to implement cryptographic primitives. krypt aims at offering performance while still improving the security and features of the Ruby cryptography infrastructure. Its motto is to keep all the good parts of what exists today and to improve the parts that need improvement. It offers an idiomatic, modern API that cherry-picks the best features of other popular libraries and also offers new features that are not offered by others today.
