This example encodes the following as:
1vbCr to "\c"
vbLf to "\l"
"\" to "\\"

This is an encryption written method that takes the 'Key' and converts each character to its ASCII value and (depending on the last total) add/subtracts the current value to the total.

This code changes a hex string eg "ed0972ba628b29f0ec" into its acsii equivalent eg "]E+'NoZûY". Useful for hex editors, using MD5 message digest checksums as keys, etc.
