Get current user's credentials object in Powershell without prompting

Question

I have a Powershell script that is going to be run through an automation tool against multiple servers. It works fine on Windows machines, as the remote calls use the tool\'

Answer 1

How about encrypting the password using the service account's encryption key?

A quick example:

Run PowerShell as the service account, run the following and save the output to a text file (or embed it in the scheduled task call):

$String = ''
ConvertFrom-SecureString -SecureString (ConvertTo-SecureString -String $String -AsPlainText -Force)

Use the following in your scheduled task in order to decrypt and utilize the password:

 $EncryptedString = ''
 [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR((ConvertTo-SecureString -String $EncryptedString)))

That should do the trick. You cannot reuse the encrypted password on a different computer, though, or if you for whatever reason destroy you local key store :)
