HMAC Basics

A HMAC is a keyed-hash message authentication code that uses an additional secret key as input to the hash function. Its purpose is to provide origin authentication and integrity assurance.

Using a secret key in HMAC adds an extra layer of security by ensuring that only the intended parties who possess the secret key can verify the authenticity and integrity of the message.

HMAC provides origin authentication and integrity assurance, which helps ensure that messages are not tampered with and can be trusted to come from the expected source.
