PBKDF2Async updates too much and is very slow. #26

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Due to the way setTimeout forces the browser to wait at minimum 4 ms before 
resuming the computation it makes the async pbkdf2 very slow, taking a full 10 
seconds with 2000 iterations. I've added a loop forcing it to compute for at 
least 100ms before returning to the browser, this gives it speed without much 
browser lag:

while (i < iterations && ((new Date()).getTime() - start.getTime()) < 100)

I've attached a copy of the source for reference.
