Hiding messages in a deck playing cards
Asher Falcon's personal website - Software engineer and student
hiding messages in playing cardsI was recently thinking about the huge number of ways you can shuffle a deck of 52 cards and wondered if it would be possible to store arbitrary data, which I explore in this blog post. I hacked together a website where I ported the functions to c++ and used WebAssembly/Emscripten to make it run in the browser Blazingly Fast 🔥, I also added a simple XOR cipher with a second string of text if you want to 'encrypt' your message before it hits the deck, but I think it's probably not neccesary as no one would suspect that you've hidden a 46 character message in your deck of cards! This whole process from thinking of the idea to implementing it was a lot of fun and I'm glad I got to share it with you.If you have any questions or comments, please feel free to reach out to me here.
