An employee is suspected of stealing proprietary information belonging to your company that he had no rights to possess. The information was stored on the employee computer that was protected with the NTFS Encrypted File System (EFS) and you had observed him copy the files to a floppy disk just before leaving work for the weekend. You detain the employee before he leaves the building and recover the floppy disk and secure his computer.

Will you be able to break the encryption so that you can verify that the employee was in possession of the proprietary information?

A.
EFS uses a 128-bit key that cannot be cracked, so you will not be able to recover the information

B.
The EFS Revoked Key Agent can be used on the computer to recover the information

C.
When the encrypted file was copied to the floppy disk, it was automatically unencrypted, so you can recover the information

D.
When the encrypted file was copied to the floppy disk, the EFS private key was also copied to the floppy disk, so you can recover the information
