Hashed Message Authentication Code (HMAC): A cryptographic technique that uses a hash function and a secret key to verify the authenticity and integrity of a message. It is used in secure communication protocols to prevent tampering and replay attacks. Examples of HMAC include using it to authenticate HTTP requests and verify the authenticity of digital signatures.
