If Alice generates a symmetric key (session key) and sends it over to Bob, the attacker could intercept it and decrypt any further communication.We’ll want to make sure that the data has not been tampered with.This solves the problem of key distribution without compromising speed, since the slower asymmetric encryption is used only for the initial handshake.chrome free vpn extension
