WebDec 29, 2024 · Currently, RSA and Diffie Hellman (DH) are the most popular encryption algorithm used on the internet. RSA relies on the "Factoring Problem," and DH relies on the "Discrete Logarithm Problem." One encryption algorithm isn't better than the other; they are just different ways to solve for encryption and are beneficial depending on the use case.
