🛡️ What is HMAC?

HMAC (Keyed-Hash Message Authentication Code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key.

  • Integrity: Ensures the message hasn't been changed.
  • Authentication: Verifies that the sender knows the secret key.
  • SHA-512: One of the strongest standard hash functions available today.
