When Is Diffie Hellman Used?

The Diffie-Hellman algorithm will be used to establish a secure communication channel. This channel is used by the systems to exchange a private key. This private key is then used to do symmetric encryption

symmetric encryption
Symmetric Encryption. Symmetric key algorithms are sometimes referred to as secret key algorithms. This is because these types of algorithms generally use one key that is kept secret by the systems engaged in the encryption and decryption processes. This single key is used for both encryption and decryption.
between the two systems.

What is Diffie-Hellman used for?

The Diffie–Hellman (DH) Algorithm is a key-exchange protocol that enables two parties communicating over public channel to establish a mutual secret without it being transmitted over the Internet. DH enables the two to use a public key to encrypt and decrypt their conversation or data using symmetric cryptography.

What's the importance of Diffie-Hellman in RSA?

Diffie–Hellman key exchange establishes a shared secret between two parties that can be used for secret communication for exchanging data over a public network and actually uses public-key techniques to allow the exchange of a private encryption key.
