-It's the same as using `crypto.subtle`, but with massively simplified API. While pure js implementation is synchronous, webcrypto is asynchronous.
+Noble implements AES. Sometimes people want to use built-in `crypto.subtle` instead. However, it has terrible API.
+
+We simplify access to built-ins. Note: it's always async.
