Decrypt Remote Desktop Manager Passwords Using Powershell

If you ever forget a server password that is stored in a Remote Desktop Manager file, you can use Powershell to decrypt the file and retrieve the password. You will need to be logged in to the same computer and account that created the file.

copy

# full path to your remote desktop manager exe
$remote_desktop_manager_exe = "C:\Projects\Tools\Remote Desktop Manager\RDCMan.exe"

# manually create this folder
$temp_files = "C:\temp"
 
Copy-Item $remote_desktop_manager_exe "$temp_files\RDCMan.dll"

Import-Module "$temp_files\RDCMan.dll"

$EncryptionSettings = New-Object -TypeName RdcMan.EncryptionSettings
 
$XML = New-Object -TypeName XML
$XML.Load($remote_desktop_file)
 
$Credentials = New-Object System.Collections.Arraylist

$logonCredentials = Select-XML -Xml $XML -XPath '//logonCredentials'
$logonCredentials | foreach {
    [void]$Credentials.Add([pscustomobject]@{
    Username = $_.Node.userName
    Password = $(Try{[RdcMan.Encryption]::DecryptString($_.Node.password, $EncryptionSettings)}Catch{$_.Exception.InnerException.Message})
    Domain = $_.Node.domain
