How to know if my bitlocker HDD is using the new encryption or old ecryption?

Hello,
How to know if my bitlocker HDD is using the new encryption (XTS) or old encryption(AES)?
And can I convert the encryption from:
a- AES to XTS?
b- 128bit to 256 bit?
Thanks

Try using Powershell and see if that gives you the data you want.

It doesn't show encryption method which is the algorithm and key size? Please post a screenshot of what you're seeing.

As you see there is nothing showing AES or XTs and 128bit or 256 bit

The outputted list, like many Powershell commands, only shows the most common properties. The property you want is EncryptionMethod. Try this

Get-BitLockerVolume | Select-Object -Property MountPoint, EncryptionMethod, VolumeStatus, EncryptionPercentage

About conversion: this would imply to decrypt and re-encrypt with the new algorithm.
