title: Launch process and hide command line parameters from Task Manager
body: <p>I'm not sure if this question is more appropriate for Stackoverflow or SuperUser or what StackExchange site...</p>
  
  <p>Basically I'm launching a third-party app from C# with <code>Process.Start</code> with several command line parameters.  One of those command line parameters is a password.</p>
  
  <p>I think I'm doing a really good job of securing that password everywhere in my app, except if you open the Processes tab in Task Manager, you can add the "Command Line" column and see all of those command line parameters.</p>
  
  <p>Can anyone think of a way to launch a process that somehow has the command line params hidden?  Is this possible at all?</p>
  
  <p>Thank you!</p>
  
  <p>EDIT:</p>
  
  <p>This is a Windows Service wrapper for plink.exe (SSH/Putty stuff).  It will prompt for a password if I don't specify the password in the command line, but I get this weird warning:</p>
  
  <pre><code>Plink.exe - 3/30/2013 2:40:47 PM - Attempting keyboard-interactive authentication
  Plink.exe - 3/30/2013 2:40:47 PM - Server refused keyboard-interactive authentication
  Plink.exe - 3/30/2013 2:40:49 PM - user@hostname.com's password: 
  </code></pre>
  
  <p>I have specified to redirect the standard input, but perhaps I will continue looking in to that and see if I can work-around it.  Also, as David Heffernan recommended, I'm going to look further into Pageant.  Thank you everyone - I will post an update once I figure out a better solution!</p>
