Passware Kit shows a “No password is set” message if no user “Password” protection was set in BitLocker encryption. This mostly means your BitLocker volume is encrypted with a recovery key that cannot be found with the brute-force method, but only extracted from a memory image or hiberfil.sys. You can read more about the protectors in BitLocker encryption here:
