现在还是用服务器中转消息，因为直接打洞不稳定，成功率太低。

安全方面用的是“两层加密”：

先用 AES 把消息内容加密（速度快）
再用 RSA 2048 把 AES 的密钥再加密一层

流程就是：

每个用户注册时生成一对密钥（公钥+私钥）
公钥上传服务器，私钥保存在自己手机/本地
发消息前，先拿对方公钥
用 AES 加密消息，再用对方公钥加密 AES 密钥一起发出去
对方收到后，用自己私钥解开 AES 密钥，再解密消息内容

服务器只负责转发消息，不看内容，传玩即删，不存数据。

所有加密,解密流程都在前端完成.

文件传输使用的切片,加密,并发上传,接收,解密,合并,输出;

还是个半成品,等完善了我在完整代码发出来;

UI有喜欢微信这种风格可以参考下面这个看看,也是ai 调校出来的,窗口是可以拖动的;
