..What many users of Bitlocker don’t know is that it defaults to 128-bit encryption, even though 256-bit is also available…
While 128-bit is the default, even Microsoft recommends using 256-bit to improve security. Problem is, most users may not know about the weaker default or how to make the change..
you may want to find out which encryption method is used on the Windows device..
Open the Start Menu.
Type CMD and activate the “run as administrator” option while the Command Prompt result is highlighted.
Run the command manage-bde -status.Windows returns a bunch of information about each volume. Check the Encryption Method status. If it reads XTS-AEs 256 you are all set and don’t need to do anything. If you get XTS-AES 128, encryption is using the weaker 128-bit method.
Problem is, Windows does not include an option to migrate from 128-bit to 256-bit. Even worse, to even get the 256-bit option, it is necessary to make a change in the Group Policy Editor…
