微信视频号解密工具 - 使用说明
|
||
|
||
📝 使用步骤：
|
||
|
||
1️⃣ 获取密钥流
|
||
方式一：使用浏览器生成
|
||
- 访问项目 GitHub Pages 或启动本地服务器
|
||
- 在页面中输入 decode_key
|
||
- 点击"生成密钥流"
|
||
- 点击"导出密钥流"下载文件
|
||
|
||
方式二：直接粘贴
|
||
- 将密钥流十六进制字符串粘贴到文本框
|
||
- 点击"从文本加载密钥流"
|
||
|
||
2️⃣ 选择加密文件
|
||
- 点击"选择文件"选择加密的 MP4 视频
|
||
|
||
3️⃣ 指定输出文件
|
||
- 输入输出文件名（默认：wx_decrypted.mp4）
|
||
|
||
4️⃣ 开始解密
|
||
- 点击"开始解密"按钮
|
||
- 等待解密完成
|
||
|
||
🔧 技术原理：
|
||
- 加密算法：Isaac64 PRNG
|
||
- 加密范围：视频前 128 KB
|
||
- 解密方式：XOR 运算
|
||
- 关键步骤：密钥流必须 reverse()
|
||
|
||
📌 注意事项：
