Store Secure Credentials in the Registry with PowerShell
This process will store secure credentials in the registry. It allows you to query those credentials and then pass them using PowerCLI to make a connection to vCenter.
This is a simple code snippet that will ask for credentials and then add them to the registry. To make this easier, you can have PowerShell create the key that will house the information and then add the proper values. I’m going to use HKEY_CURRENT_USER but feel free to store these in HKEY_LOCAL_MACHINE if necessary. To store information into HKLM, you may need to elevate your PowerShell environment to administrator. I find putting stuff in HKCU is much easier… and it has the added benefit of storing credentials with the user instead of the machine.

# Creates the structure $strRegistryKey = "HKCU:\SOFTWARE\MySoftware\Users" New-Item -Path $strRegistryKey -ItemType RegistryKey -Force # Gather credential information $secureCredential = Get-Credential -Message "Enter the username and password:" $securePassword = $secureCredential.Password | ConvertFrom-SecureString $strUsername = $secureCredential.Username # Add credentials to the registry New-ItemProperty -Path $strRegistryKey -PropertyType String -Name $strUsername -Value $securePassword |
This will add something like the following to your registry:
Notice that the Data column for administrator@vsphere.local will be the password you entered but in encrypted form.

Now that we have it stored, we need to pull the information and log into vCenter with PowerCLI.
