This FREEBITCO.DEV SCRIPT has practical uses within the online gaming and gambling field where websites can allow users to verify that the games they played using these shuffled decks were generated fairly and without alteration by the server.

When a user plays a game, the server would generate a unique serverSeed which would be kept a secret from the client, until they request it. The first time the deck is shuffled, nonce will be set to 0. Clients will always be able to see their client seed, and can also change it as they wish. Changing the client seed should automatically set nonce to 0, because it will reshuffle the deck using the new seedpair.

If the server or client wish to reshuffle the deck, the nonce should be increased by 1, which will generate a new seed for the deck and reshuffle it, while still keeping the clientSeed and serverSeed the same.
