Note

Keep in mind that you want to convert the contents of the passwordHash.txt file to a secure string and not the path to the passwordHash.txt file. The first time I attempted this operation, I used the following command: ConvertTo-SecureString C:\fso-\-passwordHash.txt, which does not work. I then realized that I was trying to encrypt the path to the file and not the contents of the file.

A more efficient way to create the password hash text file is to use pipelining and thus avoid the intermediate variable as shown here. When the command is run, it prompts for the password.

PS C:\> Read-Host -Prompt "Enter your password" -AsSecureString | >> ConvertFrom-SecureString >> C:\fso\passwordHash.txt

To use this password hash text file in a script, you can use a script like the one shown here.

Example 11-26. UsePasswordHashFile.ps1

$user = "Nwtraders\administrator" $password = ConvertTo-SecureString -String (Get-content C:\fso\passwordHash.txt) $credential = new-object system.management.automation.PSCredential $user,$password Get-WmiObject -class Win32_Bios -computername berlin -credential $credential
