What is a public key exchange (DH)?
Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key.
Aug 24, 2023 · The Diffie-Hellman key exchange was the first widely used method of safely developing and exchanging keys over an insecure channel.

The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure channel. This key can then be used to encrypt subsequent communications using a symmetric-key cipher .
Diffie–Hellman Key Exchange (DHKE) is a cryptographic method to securely exchange cryptographic keys (key agreement protocol) over a public (insecure) channel in a way that overheard communication does not reveal the keys. The exchanged keys are used later for encrypted communication (e.g. using a symmetric cipher like AES).
Diffie-Hellman key exchange is a method of digital encryption that securely exchanges cryptographic keys between two parties over a public channel without their conversation being transmitted over the internet.
This solves the key exchange problem. It can be used in conjunction with a pseudorandom generator to encrypt messages between people who have never met. Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.
