Cryptohack diffie-hellman starter 3
WebThe problem is using a key exchange method called the Diffie-Hellman key exchange. This algorithm follows a few simple mathematical formulas to create a pretty solid shared secret key. But, the more someone knows and more importantly, can influence, the worse this key exchange becomes. WebContribute to Cyber-eyes/cryptohack development by creating an account on GitHub.
