Diffie–Hellman Key Exchange - Practical Cryptography for
cryptography - "Diffie-Hellman Key Exchange" in plain Diffie-Hellman is a way of generating a shared secret between two people in such a way that the secret can't be seen by observing the communication. That's an important distinction: You're not sharing information during the key exchange, you're creating a key together. This is particularly useful because you can use this technique to create an encryption key with someone, and then start Supersingular isogeny key exchange - Wikipedia Supersingular isogeny Diffie–Hellman key exchange (SIDH) is a post-quantum cryptographic algorithm used to establish a secret key between two parties over an otherwise insecure communications channel.
Diffie-Hellman Standards []. There are a number of standards relevant to Diffie-Hellman key agreement. Some of the key ones are: PKCS 3 defines the basic algorithm and data formats to be used.; ANSI X9.42 is a later standard than PKCS 3 and provides further guidance on its use (note OpenSSL does not support ANSI X9.42 in the released versions - support is available in the as yet unreleased 1.0
Weak Diffie-Hellman and the Logjam Attack Diffie-Hellman key exchange is a popular cryptographic algorithm that allows Internet protocols to agree on a shared key and negotiate a secure connection. It is fundamental to many protocols including HTTPS, SSH, IPsec, SMTPS, and protocols that rely on TLS.

RSA and Diffie-Hellman are based on different but similar mathematical problems. While they both make use of modular exponentiation, exactly what they do/why they work is different.
