When a cryptographic disk erasure (or crypto erase) command is given (with proper authentication credentials), the drive self-generates a new media encryption key and goes into a 'new drive' state. [10] Without the old key, the old data becomes irretrievable and therefore an efficient means of providing disk sanitisation which can be a lengthy ...
USB Key Mode: The user must insert a USB device that contains a startup key into the computer to be able to boot the protected OS. Note that this mode requires that the BIOS on the protected machine supports the reading of USB devices in the pre-OS environment. BitLocker does not support smart cards for pre-boot authentication.

Multiple keys: Whether an encrypted volume can have more than one active key. Passphrase strengthening: Whether key strengthening is used with plain text passwords to frustrate dictionary attacks, usually using PBKDF2 or Argon2. Hardware acceleration: Whether dedicated cryptographic accelerator expansion cards can be taken advantage of.
Since disk encryption generally uses the same key for encrypting the whole drive, all of the data can be decrypted when the system runs. However, some disk encryption solutions use multiple keys for encrypting different volumes. If an attacker gains access to the computer at run-time, the attacker has access to all files.

9. Kansas. When it comes to expensive states for homeowners, the state of Kansas doesn’t often come to mind. But it has an average property tax rate of 1.26%.
FileVault uses the user's login password as the encryption pass phrase. It uses the XTS-AES mode of AES with 128 bit blocks and a 256 bit key to encrypt the disk, as recommended by NIST. [11] [12] Only unlock-enabled users can start or unlock the drive. Once unlocked, other users may also use the computer until it is shut down.
Hulu + Live TV: If you have an upgraded Hulu subscription that includes Hulu Live ($70 per month), you can watch “Countdown to Christmas” on the Hallmark Channel, record movies, and browse 90 ...
