Seems to me that the Diffie-Hellman key agreement protocol results in a symmetric shared private key. However, the books I've used for Security+ prep put it with RSA as a public-key algorithm.

Today we’re going to talk about how to keep information secret, and this isn’t a new goal. We’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard ...

In the 1970s, Whitfield Diffie co-wrote the recipe for one of today’s most widely used security algorithms in a paper called “New Directions in Cryptography.” The paper was a blueprint of what came to ...

Asymmetric cryptography or public-key cryptography is cryptography in which a pair of keys is used to encrypt and decrypt a message so that it arrives securely. Initially, a network user receives a ...
