autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. minitest-autotest is the latest incarnation of the venerable and wise autotest. This time, it talks to minitest via minitest-server. As a result, there is no output parsing. There are no regexps to tweak. There's no cruft or overhead.

Hanna is an RDoc implemented in Haml, making its source clean and maintainable. It's built with simplicity, beauty and ease of browsing in mind.

This implementation conforms to RFC 2898, and has been tested using the test vectors in Appendix B of RFC 3962.

In addition, NIST has stated that SHA-1 should be phased out due to concerns over recent cryptanalytic attacks.)
