What it does
HMAC is one of 55 tools in Hexkit, a desktop developer toolbox that runs entirely on your own machine. Keyed HMAC with the same set of algorithms.
Because Hexkit is a native app rather than a web page, anything you paste into the hmac stays local — there are no uploads, no accounts and no telemetry. You can generate IDs, hashes and test data even with the network turned off, which makes it safe for tokens, keys and production data.
