PowerShell to use WinSCP .NET assembly with secure credentials -

i'm trying utilize winscp .net assembly secure credential, when password secured in external file.

class="lang-powershell prettyprint-override"># load winscp .net assembly add-type -path "d:\winscpnet.dll" # setup session options $sessionoptions = new-object winscp.sessionoptions $sessionoptions.protocol = [winscp.protocol]::sftp # env $sessionoptions.hostname = "blabla.com" $sessionoptions.username = "uuuu" #$sessionoptions.password = "pppp" $sessionoptions.sshhostkeyfingerprint = "xxxxxxxxx" $remotepath = "/home/uuuu/"

with hard coded password working. if utilize securestring password, how should that?

i tried:

class="lang-powershell prettyprint-override">read-host -assecurestring | convertfrom-securestring | out-file d:\securestring.txt

to maintain secure password in file. then, in script, back:

class="lang-powershell prettyprint-override">$sessionoptions.password = get-content d:\securestring.txt | convertto-securestring $cred = new-object -typename system.management.automation.pscredential -argumentlist $sessionoptions.username, $sessionoptions.password}

but it's not working...

since winscp 5.7, assembly accepts securestring using sessionoptions.securepassword.

see http://winscp.net/eng/docs/library_sessionoptions

thanks inspiring this improvement.

while assembly keeps password encrypted in memory, still needs decrypt eventually. improvements limit internal copies of decrypted password pending.
