creat a random code from orgin code 1

generate a page that can generate many random codes from the original code, from those generated codes can be converted back to the original code, written on web platform Can search for used codes. For example, I have the code: Abcde123 => Mix random characters to create a series of new codes with the number of options: eg: aheux44, oghwi2, yiisggh, etc.... => eg i get code: aheux44 => code checker => show original code Abcde123 , => press button use aheux44 only aheux44 code is disabled. other codes are still used normally: eg: oghwi2 => test => Abcde123 etc.... Just like a one-time phone recharge code, it will no longer be used, but the top-up value will remain unchanged, can be checked by the system.
