comment Is this approach to generating a “random” number from a sha512 hash effective?
The list of participants' names might not have enough entropy to prevent you from cheating even without help from others. In particular, if you can guess who might sign up for the raffle (and in what order), you could compile a bunch of likely participant lists in advance, and, after testing a large number of possible secret inputs against those lists, select the one that has the best chance of giving you a favorable outcome if the actual participant list happens to match one of your guesses.
