The greatest ocean depth measured is in the Challenger Deep of the Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level. Oceanic lithosphere moves into trenches at a global rate of about 3 km 2 /yr.
BitLocker uses an AES encryption algorithm with a 128-bit key or 256-bit key to encrypt disk volumes. It protects the data when a hard drive is stolen and is being used on another computer or when someone has physical access to the drive. To access the drive in an offline mode, BitLocker requires a recovery key. BitLocker is generally aimed toward individual users who may fall prey to computer/laptop theft.
BitLocker can use a TPM to verify the integrity of early boot components and boot configuration data. This helps ensure that BitLocker makes the encrypted drive accessible only if those components have not been tampered with and the encrypted drive is located in the original computer.
