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.

After the PUK code is entered, the PIN must be reset. If the wrong PUK is entered ten times in a row, the SIM card will become permanently blocked and unrecoverable, requiring a replacement. Mobile phone users are therefore advised by most providers to keep their PUK written down in a safe place separate from the device.
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.
A limited number of disk encryption solutions have support for TPM. These implementations can wrap the decryption key using the TPM, thus tying the hard disk drive (HDD) to a particular device. If the HDD is removed from that particular device and placed in another, the decryption process will fail.
If you no longer have your Security Key, use these steps: Go to the Sign-In Helper. Sign in and go to the AOL Account Security page. Turn off Security Key 2-Step Verification. When you get your Security Key back or get a new key, you can re-enable 2-Step Verification in your Account Security settings.
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.
Locking your keys in your car is never fun—especially when you’re running late. Here’s a tip: Keep a roll of string around, and you’ll never have to cash out for a locksmith again. Don’t ...
