-/**
-  * Generic function to derive Hawk credentials.
-  *
-  * Hawk credentials are derived using shared secrets, which depend on the token
-  * in use.
-  *
-  * @param tokenHex
-  *        The current session token encoded in hex
-  * @param context
-  *        A context for the credentials. A protocol version will be prepended
-  *        to the context, see Credentials.keyWord for more information.
-  * @param size
-  *        The size in bytes of the expected derived buffer,
-  *        defaults to 3 * 32.
-  * @return credentials
-  *        Returns an object:
-  *        {
-  *          algorithm: sha256
-  *          id: the Hawk id (from the first 32 bytes derived)
-  *          key: the Hawk key (from bytes 32 to 64)
