About the XOR table key and decryption method

[latot]

Hi hi, I was thinking to start a projecto about SW, and I found a lot of this project, the nice ting is every project can help others :3

My question here, is about the method to decrypt the network packets with XOR, Here other project:
https://github.com/HoLLy-HaCKeR/SWSniff/blob/master/SWSniff.SoulWorker/GeneralHelper.cs
https://github.com/HoLLy-HaCKeR/SWSniff/blob/master/SWSniff.SoulWorker/Constants.cs

As you can see, the way to decrypt is very similar to here, with some differences...

My point there is, did you find some way to can test the decryption method? even if the two methods (from here and the other project) are pretty similar, the results are differents.

Thx.
