| The Diffie-Hellman algorithm is foundational in various security protocols, such as TLS (used for secure communication on the Internet) and VPNs (Virtual Private Networks). It ensures that only two parties can generate a shared key that they can compute, even if an attacker monitors the communication channel. | The Diffie-Hellman algorithm is foundational in various security protocols, such as TLS (used for secure communication on the Internet) and VPNs (Virtual Private Networks).
