An implementation of the Massey-Omura Cryptosystem
This project was implemented in Python language using gmpy2 library.
There are 2 main entities, the client and the server, which we can call Alice and Bob respectively.
Alice wants to send a message to Bob in a secure way but without the need to exchange any kind of keys.
Infact, using this protocol there is no need of that. That's because the encryption and decryption functions are commutative.
Mathematical properties of congruences allows us to do that.
