Recover OpenVPN Saved Password
Per the OpenVPN GUI source code, saved passwords are stored in the registry under HKCU\Software\OpenVPN-GUI\configs
.
The Powershell script in this link gets the password for me: OpenVPN Password Recovery
The registry names on my computer are a bit different; my version:
$keys = Get-ChildItem "HKCU:\Software\OpenVPN-GUI\configs"
$items = $keys | ForEach-Object {Get-ItemProperty $_.PsPath}
foreach ($item in $items)
{
$encryptedbytes=$item.'auth-data'
$entropy=$item.'entropy'
$entropy=$entropy[0..(($entropy.Length)-2)]
$decryptedbytes = [System.Security.Cryptography.ProtectedData]::Unprotect(
$encryptedBytes,
$entropy,
[System.Security.Cryptography.DataProtectionScope]::CurrentUser)
Write-Host ([System.Text.Encoding]::Unicode.GetString($decryptedbytes))
}
You may also need to execute Add-Type -AssemblyName System.Security
in Powershell to make it work.
edit: on windows 10, OpenVPN v11.9, $encryptedbytes=$item.'key-data'
