AlgorithmicOnBigNumber

Introduction and context

This code was created for a school work. The purpose of this repository is to implement operations on big numbers necessary for cryptographic purposes (i.e. 1024 bits AES, 256 bits RSA...).
Of course, more advanced and probably perfomant library exist for theses operations. But it was really intersting to face the difficulties of coding these operation in C++.

Operation implemented

The following operations have been implemented :

• Modular addition
• Modular substraction
• Modular mutliplication
• Modular exponentiation (using montgomery algorithm)
