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 38 CF A0 DD 85 C0 10: C7 9B C4 D8 DD 28 8A XX XX XX XX XX XX XX XX XX 20: XX 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 XX
