This is a “Hazardous Materials” module. You should ONLY use it if you’re 100% absolutely sure that you know what you’re doing because this module is full of land mines, dragons, and dinosaurs with laser guns.

While cryptography supports both the CMAC and HMAC algorithms, we strongly recommend that HMAC should be used unless you have a good reason otherwise.
