gohide是一款功能强大的网络通信数据加密工具,该工具可以通过一个模糊信道来对信道中的端到端数据进行AES-GCM加密。
1、会话Cookie HTTP GET(http-client)
2、Set-Cookie会话Cookie HTTP/2 200 OK(http-server)
3、WebSocket握手“Sec-WebSocket-Key”(websocket-client)
4、WebSocket握手“Sec-WebSocket-Accept”(websocket-server)
5、none-无混淆,仅使用AES-GCM加密消息
默认配置下,gohide将针对上述每一个选项启用AES-GCM加密。
由于该工具基于Go语言开发,因此我们首先需要在本地设备上安装并配置好Golang环境。接下来,使用下列命令将该项目源码克隆至本地:
git clone https://github.com/Potato-Industries/gohide.git
[email protected]:/opt/gohide-dev# ./gohide -h
Usage of ./gohide:
-f string
监听伪造的服务器-r x.x.x.x:xxxx (ip/域名:port) (默认"0.0.0.0:8081")
-key openssl passwd -1 -salt ok | md5sum
AES加密密钥: 使用'-k openssl passwd -1 -salt ok | md5sum' 从密码中获取密钥 (默认"5fe10ae58c5ad02a6113305f4e702d07")
-l string
监听端口转发-l x.x.x.x:xxxx (ip/domain:port) (默认"127.0.0.1:8080")
-m string
混淆模式 (默认启用AES加密): websocket-client, websocket-server, http-client, http-server, none (默认"none")
-pem string
用于TLS加密模式的.pem文件路径: default = 使用硬编码密钥对 'CN:target.com', none = plaintext mode (默认"default")
-r string
转发至伪造的远程服务器-r x.x.x.x:xxxx (ip/域名:port) (默认"127.0.0.1:9999")
