nonce question #18

Closed element6 closed 9 years ago

Hi,

Perhaps this is something I don't know about javascript. If you initialize nonce in the constructor as Date.now(), then generateNonce function returns nonce++. Wouldn't that always be unique as long as you use the same object?

I've read the comment, I think I've got my answer.

To further clarify: Calling Date.now() will give back a Date object representing the current time (the object will always be unique). Saying nonce++ on that object will force it to it's numerical representation (and add 1 to it), which in the case of a Date object is the timestamp in ms. When you call the function multiple times you'll get different date objects that boil down to the same timestamp in ms.

The padding makes sure that this still results in a different nonce.
