Take a sample of Plain text, encrypt this plaintext step by step using AES, you must show each step how it has been done with all tables and codes, till you generate the Ciphertext. the reverse your work step by step until you generate the Plaintext Your plaintext is: “Here you can encrypt a block of bytes with a key using the popular Advanced Encryption Standard cipher” . All the internal steps of the computation are shown, which can be helpful for anyone debugging their own AES implementation. In each of the 10/12/14 rounds, the sub-steps of SubBytes, ShiftRows, MixColumns, AddRoundKey, and key schedule are shown”

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 7 years. My work is online game developing, and mainly focus on server side, using c++ under Linux environment. I made many great projects using c++, for example, I made the tools which could convert java codes into c++ scripts, of course garbage collection included, this was very similar to a compiler, and was very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.

I am Computer Engineering graduate and am doing my masters on Computer Science. I've recently took Cryptography as a graduate course (thus I am familiar with AES). I am also fluent in C/C++/Java (which ever you prefer). If you would prefer, lets discuss the details and you can decide if you want to work with me. Cheers.
