User doesn't know server seed in advance. User only knows encrypted server seed - for future check if roll was fair. Website doesnt know client seed in advance.
The server/site doesnt know the client seed in advance?
You make set your own seed/make it what you want it to be, and click submit.
So theres no way the website, server, who you enter that information into and click submit, could possibly get that seed?
Its a webform. You're submitting a variable and clicking send.
Are we just taking their word for it that they would never "peek" at our cards?
Also, wouldnt they in addition regardless if the above is correct, that they would have no way to see what we click to send to them, wouldnt they know our seed after one roll? They would have to hash roll 1 in order to get the outcome.
