Question

What is the correlation does Diffie-helman has with RSA? like is diffie-helman important for the understanding RSA, or are they completely different entities who do their own thing

Answer 1

Answer:

Diffie-Helman is a key exchange algorithm whereas RSA is a public key encryption algorithm. RSA and Diffie-Helman are based on different concepts but have similar mathematical problems. RSA uses modular exponentiation to provide encryption or signature and Diffie-Helman uses modular exponentiation to provide the key agreement so how they are using modular exponential and why they work is different. So we can say both are different entities who do their own thing but remember we can turn Diffie-Helman into a public-key encryption algorithm.
