There probably aren't many people using to encrypt their traffic any more, but in case anyone was thinking about it, please don't.

Breaking the encryption of this tool was a challenge for Real World CTF 2020.

By defaul the tunnel uses AES-CFB with a static Initialisation Vector, so multiple connections are encrypted using the same keystream. Furthermore, the streams are malleable, so an adversary can capture your traffic and decrypt it by replaying it through your own proxy server.

Here is a full writeup

what is the difference between shadowtunnel and stunnel? better performance?

please support daemon mode,support params like --daemon,--forever and --log etc.

非常好，已经用起来了，配置也比SSR简单很多

为了方便家里和手机端使用，我把客户端配置到了一台国内的vps上，switchyOmega只要配置这个地址就能使用。

这样就有一个问题，如果别人知道了我的服务器地址或者客户端地址，就能随意的使用，这一点是非常不安全的，希望增加用户认证的功能。

Hi,
Is exist showtunnel for "Android" OS?

mac上应该下哪个版本呢，我下的Linux-amd64，但是运行提示exec format error: shadowtunnel

Hello ,I had a server side shadowtunnel crash, client and server version is v1.1
server cmd:

setsid ./shadowtunnel -u -e -f 127.0.0.1:38080 -l :50000 -p 123456 >shadow.log 2>&1 &

client cmd:

./shadowtunnel -E -U -f x.x.x.x:50000 -l :50000 -p 123456

例如用json写配置文件，然后 shadowtunnel -c config.json 这样启动？

Hi,
I downloaded this project and I run it but I got this error in building:
cannot find package "github.com/snail007/proxy/core/dst"
Is exist this repository (github.com/snail007/proxy)? I cannot find this repo anywhere. Any help, please.

我现在有2个vps，都安装了goproxy 和shadowtunnel，我想要在本地局域网服务器上监听一个端口，然后能够通过隧道将流量转发到2台vps上。
我使用这个命令可以正常监听，但是日志显示只与其中一台建立了连接：

shadowtunnel -E -f 1.1.1.1:5000 -f 1.1.1.2:5000 -l :5000

当停掉建立连接的服务器上的服务时，流量并没有切换到另一台上。

发现新版增加了 -c 参数，试着两边都加了 -c 参数用了一下，但是发现无法建立连接。

请问 -c 参数怎么用呢？ 是不需要解压缩的参数吗？
