Getting ready

In this recipe, we will create a database master key for the master database. You can substitute a different database for this exercise if you wish.

The T-SQL equivalent of what we are trying to accomplish is as follows:

   $server = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Server -ArgumentList $instanceName

3. Add the following script and run it:

   $VerbosePreference = "Continue"
   $masterdb =  $server.Databases["master"]
   
   if($masterdb.MasterKey -eq $null)
   {
      $masterkey...
