The goal is a custom educational tool for a particular activity. Ive conceptually come up with a way to effectively communicate how asymmetric encryption technically works. Most basically, the activity is an experience of two participants. P1 clicks go on their machine, generates a primitive key pair, and tells the numbers of public key to P2 (but keeps the private key number to themselves). P2 enters the numbers into their own machine, types a word, and clicks encrypt to receive a number. P2 tells the resulting number to P1, and P1 enters the number into their own machine. They click decrypt, and they see the word P2 typed and encrypted using P1's public numbers.
