So I'm trying to decrypt/decode some text strings. I don't believe they're hashes because they vary in length too much and the software they are used for is able to easily decode them and display them to the user. (I also have no access to the source code) My end goal is to be able to replace the encoded text with my own encoded text so what ends up being displayed is changed.
Some examples of the encoded text:
EDIT in response to the Hold: I'm not asking for these to be decoded for me. I'm asking how I would go about doing it. Also I'm not breaking into a system...
