Implement simplified version of DES in R

- I have 4 years of strong experience working in C, C++, Python and R programming languages. I have worked on many Data Science/ Machine Learning projects. - I have studied block ciphers and have understood DES well. Thus I have clearly understood the requirements for the project. - I will make sure that the project gets completed with the utmost care and reach the best of your expectation standards because I believe client satisfaction is more important than monetary rewards.
