Knowing how to interact with encrypted values is very important with memory editors like GG (and not only for mem editors).
It is hard to understand written as that, see my last paragraph.
To find Xor key + value:
I began a mission and I did exact search with encrypted value checked. I found the encrypted value. To find the xor key, you push modify button on the value, then the arrow on the right, you go in the last tab and put the real value in the box. You push OK and now the xor key replaced the encrypted value in the window.
To use Xor key (find value/modify it):
If you want to change the encrypted value or search for it (for next mission, because its place change each time), copy this xor key I gave you (or you can find it by yourself as explained before), go to modify or exact search tab, put the non encrypted score value you want or the one you can see in game, then right arrow, last tab, paste the key, OK, and you can search or edit the value now.
--> once you used a xor key on a game, the "XOR 0 = ..." tab can be a shortcut to use the last xor key entered (it replaces the "...") for this game.
If you want more help about encrypted values in GG, watch eniby's video tutorial on the forum about XOR encryption, he shows what I said here but it is much more easy to understand with a video. Btw you should really take a look at tutorials section of the forum, it is really helpful.
