You've got a few options: - Random Caesar Cipher: less predictable, doubles length of the string - Pseudorandom Caesar Cipher: more predictable, keeps length of the string the same - Shuffle characters: shuffles the characters by placing the last and first characters next to each other, then the second-last and second first, and so on; adds complexity - Characters to numbers: turns characters to numbers, very predictable, doubles string length Thanks to Julius Caesar for helping me
