Script Breakdown

1. Function Definitions

Test-Proxy Function

function Test-Proxy {
    param (
        [string]$proxy
    )

    $url = "http://google.com" 
    $proxyUri = "http://$proxy"

    try {
        $request = [System.Net.HttpWebRequest]::Create($url)
        $request.Proxy = New-Object System.Net.WebProxy($proxyUri, $true)
        $request.Timeout = 5000  

        $response = $request.GetResponse()
        $response.Close()
        return $true
    } catch {
        return $false
    }
}

• Purpose: This function tests if a given proxy server can successfully make a request to http://google.com.
• Parameters:
  • $proxy: A string representing the proxy server in the format address:port.
• Details:
  • HttpWebRequest is used to create an HTTP request.
  • New-Object System.Net.WebProxy($proxyUri, $true) sets the proxy for the request.
  • Timeout is set to 5000 milliseconds (5 seconds).
  • GetResponse() attempts to get a response from the URL.
  • If successful, the function returns $true; otherwise, it returns $false if an error occurs.

Check-ProxiesFromFile Function

function Check-ProxiesFromFile {
    param (
        [string]$filePath
    )

    if (-Not (Test-Path $filePath)) {
        Write-Host "File not found!" -ForegroundColor Red
        return
    }

    $proxies = Get-Content $filePath
    foreach ($proxy in $proxies) {
        if (Test-Proxy -proxy $proxy) {
            Write-Host "$proxy > Google: yes | Chk by Spishere" -ForegroundColor Green
        } else {
            Write-Host "$proxy > Google: no | Chk by Spishere" -ForegroundColor Red
        }
    }
}

• Purpose: This function reads a list of proxy servers from a file and checks each one to see if it can connect to Google.
• Parameters:
  • $filePath: The path to the file containing the list of proxies.
• Details:
  • Test-Path checks if the file exists.
  • Get-Content reads the content of the file (assumed to be a list of proxy addresses).
  • For each proxy in the file, Test-Proxy is called to check its connectivity.
  • Write-Host outputs the result of each proxy check, with color-coded messages indicating success or failure.

Show-AsciiArt Function

function Show-AsciiArt {
    $asciiArt = @"
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄

}

• Purpose: This function displays ASCII art in the PowerShell console.
• Details:
  • $asciiArt contains a block of text representing the ASCII art.
  • Write-Host outputs the ASCII art with cyan color.

Script Execution
