public class Hmac

HMACs should be used when producing a cookie or hash based on data and a key.

Simple mechanisms for using SHA1 and other algorithms to digest a key and data together are vulnerable to various security issues. HMAC uses algorithms like SHA1 in a secure way to produce a digest of a key and data.

Both the key and data are arbitrary byte arrays of bytes or characters.

Support for HMAC Digests has been added in GLib 2.30, and support for SHA-512 in GLib 2.42. Support for SHA-384 was added in GLib 2.52.

To create a new `GHmac`, use [ctor@GLib.Hmac.new]. To free a `GHmac`, use [method@GLib.Hmac.unref].
