收到了日本朋友的邮件看了一眼这不是早就暴毙的 女神降临/Goddess Arrival 吗
这还能肘赢牢大打赢复活赛我是真没想到…
与前作稍有一点不一样UI更新了（按理说是原作苍空物语更新的UI…）
加密只有H资产的png加密了
这里也给想学的小白一个参考如何快速定位这种cocos2djs在线页游的解密代码
直接打开“发起程序”
可以看到是index,js拉起的加密png下载
转到上下文后可以看到有个decryptImageDataInPlace函数调用名字已经暴露一切
然后找到函数原型
参考python解密代码
import os
def decrypt_image_in_place(data: bytearray, t: int):
n = len(data)
a = (n // 2) - (t // 2)
for i in range(t):
r = a + (i % t)
data[i] ^= data[r]
data[n - t + i] ^= data[r]
return data
def decrypt_file_in_place(file_path, t=50):
with open(file_path, "rb") as f:
data = bytearray(f.read())
# 直接判断文件头是不是合法png头来判断是不是加密文件
if data[:8] == b'\x89PNG\r\n\x1a\n':
print(f"跳过已解密文件: {file_path}")
return
print(f"解密文件: {file_path}，长度: {len(data)} 字节")
decrypt_image_in_place(data, t)
with open(file_path, "wb") as f:
f.write(data)
print(f"已覆盖原文件: {file_path}")

decrypt_file_in_place(file_path, t)
if __name__ == "__main__":

顺带问一问谁保留了原来老版本的数据包
可以参考这个解密
似乎这个新版本还少了几个角色的cg
