Binary Copy of encrypted drive

Hello,

If I have an encrypted drive (with known password)  is it possible to create E01 binary copy of it using FTK Imager? Does FTK will see the encrypted drive on the list ?

Is this procedure (creating E01 encrypted copy) any diffrent than from an unencrypted drive?

Or should I first somehow decrypt the drive using known password and then create binary copy?

After creating E01 of encrypted drive is it possible to add this created e01 copy to Magnet Prcoess and then decrypt this using known password ? 

Thanks in advance for any clues.
