Hi,
I have great experience in implementing both symmetric and assymetric cryptographic algorithms from scratch in C, C++ and Python. I have checked your attached document and I understood that you need an implementation of RSA and One Time Pad etc.
I can definitely help you implement this perfectly in the shortest time possible! I will be using Python to implement this project!
Please feel free to contact me via chat so that we can discuss further and start working on this amazing project right away!!!
Best Regards,
Aravind A
