||
timeout in milliseconds. no timeout when not given

|
||
### OSX
|
||
运行 `$ spoof-dpi` ，然后它会自动设置自身为代理
|
||
|
||
### Linux
|
||
运行 `$ spoof-dpi` 然后加上代理参数运行你的浏览器
|
||
|
||
`google-chrome --proxy-server="http://127.0.0.1:8080"`
|
||
|
||
# 工作原理
|
||
|
||
### HTTP
|
||
|
||
因为世界上许多网站都已支持 HTTPS ，SpoofDPI 不会规避对 HTTP 请求的 DPI，但是它仍会为 HTTP 请求提供代理。
|
||
|
||
### HTTPS
|
||
尽管 TLS 1.3加密了握手的每一步，但是在 Client Hello 中的域名仍然是明文的。因此如果有人看到 Client Hello 包就可以知道你在连接什么网站。这给 DPI 提供了很大方便，我们也看到连接在 Client Hello 之后就会被屏蔽掉。我之前尝试了规避这种审查，并发现，如果把 Client Hello 分包，只有第一个 chunk 会被检测。SpoofDPI 只要在第一个分包发送 1 byte，然后再发送其他部分就能规避。
|
||
|
||
> SpoofDPI 不会解密 HTTPS 请求，所以您无需安装任何 TLS 证书。
