説明
I like the idea of this library, and I tried using it for a toy app; the challenge I have is that it would be extremely natural to use createId in class constructors, but these cannot be async and using createId(..).then(...) results in type warnings since the result cannot be definitively assigned.
I see you are building the key functionality on top of crypto.subtle and I imagine its not easy to find a work-around. Also, usually I am happy to use async APIs, but in this case its challenging.
