Interesting. Can you explain how you are generating ECDA private key from the current deck
I have created two math functions, one converts each sequence of cards to a unique decimal number, and the other converts a decimal number to a unique sequence of cards. Once I create the downloadable version you will be able to see the source code for the two functions. I'm trying to get a patent on this for use in the casino industry. As soon as this is done, I'll be able to publish the code.
