KMAC128 File Hash
The KMAC128 File Hash tool computes a secure SHA-3 based Message Authentication Code (MAC) for any file using a secret key. You can also add optional Function Name (N) and Customization String (S) parameters. All file hashing is processed entirely in your browser — your file and key never leave your device.
