I’m not participating in the challenge, but I wanted to show that it is possible to make this without any component. Even more, I made a simple coding and decoding system that generates a different code for the same string every time is called, and of course is totally reversible. The only drawback is that it doesn’t encode emojis.
This coding is not unbreakable but without seeing the encoding process it will be hard to find out.
(Thanks to @Taifun for his LEADING ZEROES procedure)
These are the procedures for this encoding. Like I said, no emojis. It could be implemented, but I will leave that for you guys, if you want to.
