a full deck of cards provides 225.58 bits of entropy −52! combinations =log2(52!) bits of entropy.

So I'm just wondering where you found 232 bits of entropy?

Either way its damn tough to crack so should be a good way to transfer a key as long as no one knows and your going to move the funds as soon as you get where your going. Interesting thought. You could increase with the jokers and rules card as well.

Maybe I put too many cards in?? I was using the Ian Coleman BIP39 tool.

But to the point of jokers and rules.. you can also just add 6 more cards to get to 256bit, I think. So you could add six cards for a second deck.

I think another way to increase entropy is to shuffle between draws. So you can have repeating cards. (Creates a poisson distribution like POW is) And if you had enough decks of cards you could also build this "custom deck' just don't try to deal a hand of poker with it. Wink
