RSA-OAEP Encrypt-then-Sign Messaging Tool

Machine Problem 2 Group Members: Deen, Ligero, Torres Introduction This machine problem involved designing and implementing a secure messaging system using public-key cryptography. Unlike the previous exercise—where the goal was to break a program's security—this one required building security in from the ground up. The objective was to construct a command-line tool that allows users to exchange messages with two guarantees: Confidentiality – only the intended recipient can read the message Auth
