User:Remark/Flipbook XOR Pad
Since the encryption used is AES-128-CTR, there's a static XOR pad (generated from the key) applied when encrypting/decrypting. Here's the XOR pad used for the *.lst file (hexadecimal):
00: XX XX XX XX XX XX XX 37 6E 11 40 BC A0 AB 8E 10: B0 CD EB 9B A3 DD 28 8A 87 XX XX XX XX XX XX 20: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX 30: XX XX XX XX XX XX XX XX XX XX XX XX XX XX XX
