go-proxy-aware-sspi

A simple Go module for transparent Windows proxy authentication calling SSPI, similar to curl's "-U :" feature.

Installation

go get github.com/superpb9/go-proxy-aware-sspi

Features

• Transparent Windows proxy authentication using SSPI
• No explicit credentials required (uses current Windows user context), similar to curl's "-U :" functionality
• For study/researching purpose, currently implementing websocket connection as an example

Usage Example

package main

import (
    "log"
    "github.com/superpb9/go-proxy-aware-sspi/wsconnect"
)

func main() {
    websocketURL := "wss://example.com/websocket"
    proxyURL := "http://proxy.example.com:8080"
    
    // Connect through proxy using current Windows user credentials
    conn, err := wsconnect.Connect(websocketURL, proxyURL)
    if err != nil {
        log.Fatal(err)
    }
    defer conn.Close()

    // Use websocket connection...
}
