【公式ゲーム】あいりすミスティリア！～少女のつむ …

如题，我想了解一下该游戏的数据包该怎么拉取，万分感谢

挺适合练手的游戏，我这里只给出一些解密函数，其他的自己抓包写

import hashlib
import struct
import hmac
from Crypto.Cipher import AES
from Crypto.Util.Padding import unpad

if __name__ == "__main__":
    k = hmac.new(b"dB3aqcLtAmBd", b"RWd3NusabzRc", hashlib.sha256).digest()

    with open("003le.encrypted", "rb") as f:
        d = f.read()

    if len(d) > 4:
        l = struct.unpack("<I", d[:4])[0]
        if l + 4 == len(d):
            d = d[4:]

    dec = unpad(AES.new(k, AES.MODE_CBC, iv=d[:16]).decrypt(d[16:]), 16)

    with open("003le", "wb") as f:
        f.write(dec)

老代码写的乱，但补全配置后应该能将就着用，用不了我也不管，当个思路(
视频文件头的XorKey = b’\xd5\xc5\xc4\xb7’

def decryptdata(data: bytes, aeskey=aeskey) → bytes:
cipher = AES.new(aeskey, AES.MODE_CBC)
return cipher.decrypt(data)[16:]

如果你明白CBC以及iv到底是什么以及在干什么，那么这么写也是没问题的，但不建议在正规项目用(
