When you say 'XOR', is it just a rolling XOR, or is there a specific batch size? (as in: Every X bytes is XOR'd by the key size in bytes)
If so, I'm getting nonsense. Got any examples of files you successfully decrypted, which key and its encrypted/decrypted hashes?
Also, is the keys for global, Taiwan or both (referring to the mobile versions)?
For example:
00c5bd21e86ca69e6e30fb033f10ee80 (36kB) = 8AE68080257CBB0E133DA979FB919376D17B1F4B0F72676A339CBE55B525C859
XOR'd 7 bytes: 4ABE2FD9C3787879CD3EF97F3CC8767706F18D84E581C17AD1D0B3E03ACA611F
XOR'd 8 bytes: FF1894E6791E988D9032BD1F09D903443034D85835832BF3B4CDDAB73B74C50D
XOR'd 9 bytes: 7C312050D0F7B80E3B32C19395FF9414605373EC9A9805D4A0AC8A21A051EA33
XOR'd 10 bytes: 75BD8289C2AE1971F24BC019F76875D21A7F55973E4D1F5067BC89891C55597D
Okay, I just double-checked against the Taiwan version, I think it might've been encrypted with a different cypher; XOR key.
The same file, encrypted in the Taiwan Android version has hash B03CBED6961F1A9D49AB66C27E64571E3EDEEF775C7DF1F87CC6BE0DF21840C5
Edit: I'm probably doing it wrong, because the Taiwan Android version is also gibberish to me after XORing.
