Why is crypto.subtle.digest async? (programming.dev)

Why is crypto.subtle.digest designed to return a promise?

Every other system I've ever worked with has the signature hash(bytes) => bytes, yet whatever committee designed the Subtle Crypto API decided that the browser version should return a promise. Why? I've looked around but I've never found any discussion on the motivation behind that.
