Use System.Text.Encoding.Unicode.GetString to convert the CredentialBlob into a password string.

If it's legal for PInvoke.net to swipe Microsoft's own code, the stuff here is even better:

$password = "password"

$cred.credentialBlobSize = [System.Text.Encoding]::Unicode.GetBytes($password).length

$cred.credentialBlob = [System.Runtime.InteropServices.Marshal]::StringToCoTaskMemUni($password)

System.Security.Cryptography.PasswordDeriveBytes and call the CryptDeriveKey.
