尝试使用签名范围搜索密钥
签名 xjdzEncrypt
密钥 xjdzaabbccddeeffgghh
但是xxtea无法解密
这种js引擎的需要使用索引文件但是我没有在res文件夹下找到任何config文件
import os
HEADER = b"xjdzEncrypt"
KEY = b"xjdzaabbccddeeffgghh"
KEY_LEN = len(KEY)
def decrypt_file(file_path):
try:
with open(file_path, "rb") as f:
data = f.read()
if len(data) < len(HEADER):
return
if not data.startswith(HEADER):
return
encrypted = data[len(HEADER):]
decrypted = bytearray(len(encrypted))
for i in range(len(encrypted)):
decrypted[i] = encrypted[i] ^ KEY[i % KEY_LEN]
with open(file_path, "wb") as f:
f.write(decrypted)
print(f"[Y] {file_path}")
except Exception as e:
print(f"[-N-] {file_path} -> {e}")
def decrypt_directory(root_dir):
for root, dirs, files in os.walk(root_dir):
for name in files:
file_path = os.path.join(root, name)
decrypt_file(file_path)
decrypt_directory(r'69ba8af2561df4.74886084-spj2-2020318-release-v1.0.0.9\assets\res')
交叉引用一下就能看到其实是异或
我也没找到config文件倒是main.js没加密
包含一段
// init assets
cc.AssetLibrary.init({
libraryPath: 'res/import',
rawAssetsBase: 'res/raw-',
rawAssets: settings.rawAssets,
packedAssets: settings.packedAssets,
md5AssetsMap: settings.md5AssetsMap,
subpackages: settings.subpackages
});
没见过

大佬们牛逼，解加密来自吾爱，
jsc解加密工具-Orange.zip (1.6 MB)
挖一下，今天心血来潮，尝试提取文件，看见了一个非常符合我喜欢的角色CG,使我想要魔改，去除了背景，把男的删除了，把JJ换成了大茄子。分享一下 
（原来的右膝盖是缺失一部分的，ps技术有限，补全的有瑕疵，将就一下吧，哈哈）
