# Diffie-Hellman Key Exchange

> Diffie-Hellman Key Exchange is a core cryptography concept in cybersecurity. It describes techniques, risks, or controls that defenders and ethical hackers must understand to protect systems and conduct authorized security testing. Learning Diffie-Hellman Key Exchange helps you recognize attacks in the wild and apply industry-standard mitigations aligned with frameworks like OWASP and NIST.
