Posting encryptions

[godofcereal]

If you are going to post your custom encryption here please put some of the following in:
- Piece of the key e.g. A=1 B=2 etc.
- An example of the encryption key in use and decoded e.g. 456=def
- If there is a certain way to crack it that you made thats impossible for anyone of us to get, leave a clue how to.
- When/if someone cracks it, give a brief description how you made the encryption key.
These are just a few things I'd like people to know before posting your encryptions here. We do enjoy a challenge, so bring your toughest codes here.

This took me 5 minutes or so to write, so I don't suppose it'll be too hard
Will post source if anyone wants it.

"hello world" -> "76~106~115~118~125~51~112~143~154~157~159"

Try and decode:
"106~119~108~111~46~116~140~64~145~159~91~172~196~196~210~224~251~266"

Have fun.
