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.
Rekeying a lock is replacing the old lock pins with new lock pins. Locks are usually re keyed to build master-key systems, make a set of locks share a common key, or to eliminate compromised keys. Sometimes worn pins are replaced with new pins if the old pins become too short to reach the shear-line. The shear-line is the thin line shared by the plug and it's cylindrical housing.
