This patch introduces a helper crypto.hash() that computes a digest from the input at one shot. This can be 1.2-1.6x faster than the object-based createHash() for smaller inputs (<= 5MB) that are readily available (not streamed) and incur less memory overhead since no intermediate objects will be created.
