About HMAC

HMAC (Hash-based Message Authentication Code) is a keyed hash function used to provide data integrity and authentication. It combines a cryptographic hash function (like SHA-256 or SHA-512) with a secret key.

Why Use HMAC?

  • Data Integrity: Verify that data hasn't been tampered with.
  • Data Authentication: Verify that data originates from a trusted source.
  • Security: Provides strong authentication when a secret key is kept confidential.

Examples

Example 1: Data: "My secret message" Key: "mysecretkey" Algorithm: SHA-256 Output: (HMAC hash)
