Diffie-Hellman's Lasting Impact: The Algorithm That Redefined Secure Online Communication

• Flexibility: Diffie-Hellman can be used in various applications, including online transactions, data encryption, and secure communication protocols.

Diffie-Hellman is a cryptographic algorithm that enables secure communication over an insecure channel. It relies on the concept of public-key cryptography, where a pair of keys – a public key and a private key – is used to encrypt and decrypt messages. The public key is used to encrypt the message, while the private key is used to decrypt it. The Diffie-Hellman algorithm allows two parties to agree on a shared secret key over an insecure channel, without actually exchanging the key itself. This makes it a powerful tool for secure communication.

Diffie-Hellman is a public-key algorithm, using a pair of keys to ensure secure communication.
