Just as the name implies, this is a DES Ruby Implementation. It is a homework assignment of BUAA Software Engineering's information security course. Wang Haiquan is the lecturer of this course. And Yu Yang is the TA.
I'm asked to implement DES using C or Java, but I haven't been coding C/Java for a long time, and more familiar with scripting languages like Python, CoffeeScript/JavaScript, Ruby. So I decided to implement DES in Ruby first as a good starting point, then rewrite it using C or Java.
What's DES? -----------Please check this wiki page.
What's Ruby? ------------You can check its offical website, or this wiki page if you prefer.
Who Are You? ------------I'm Labi Kyo ( Li Xinyue ), BUAA Software Engineering Junior, web developer, starter. Love Python,Ruby and JavaScript, write nodejs/Rails.
Why You Create This Repository? -------------------------------I know there are thousands of implementation for DES and mine might be the worst, I just do it in order to prove that I implement this algorithm myself. It's also a practice for BDD, sharing and open-source coding. Also, I want to have some code to show my future employe{r,e} and friends.
It's the first time I follow GPL's document and really use a license. It's also the first time I use markdown to write documents. I'm feeling pretty good and I'd like to contribute more open-source codes.
