tcpcrypt-master

代码说明：

说明：  tcpcrypt是一种协议，它尝试加密（几乎）所有网络流量。与其他安全机制不同的是，tcpcrypt是开箱即用的：它不需要配置，不需要更改应用程序，而且即使远程端不支持tcpcrypt，您的网络连接也将继续工作，在这种情况下，连接将优雅地返回到标准的明文tcp。(Tcpcrypt is a protocol that attempts to encrypt (almost) all of your network traffic. Unlike other security mechanisms, Tcpcrypt works out of the box: it requires no configuration, no changes to applications, and your network connections will continue to work even if the remote end does not support Tcpcrypt, in which case connections will gracefully fall back to standard clear-text TCP.)
