How to use BitLocker Drive Encryption

Introduction to BitLocker encryption:

BitLocker in simple terms this component is a combination of a soft and hard way (BitLocker with the hardware TPM chip) together to protect the hard disk data, the biggest bright spot is that even if the hard drive to other computers, can not read any information. BitLocker can not only encrypt any partition, but also add encryption support for U disk and removable hard disk, which is also called BitLocker to go.

　　BitLocker encryption Step:

1. Enter the control panel to find "BitLocker Drive Encryption" click Enter.

2. This interface can be seen including hard disk partitions, as well as U disk, mobile hard disk and so on. Turn on encryption by clicking "Enable BitLocker" after you want to encrypt the drive.

3. After a short wait, BitLocker will eject the encryption method selection. One is the most common password encryption, and the other is the "smart Card (TPM) Unlock" We mentioned earlier (some business machines may be equipped).

4. After entering a good password, select "Save recovery Key to file" or "Print Recovery key" (be sure to keep in good order). Encryption is implemented later, depending on the amount of data.

After unlocking BitLocker encryption is complete, BitLocker begins to formally start protection. At this point if you plug it into another computer (including this machine), will first pop-up a dialog box, enter the correct password can be read out of U disk files.

Compatibility Since needless to say, after BitLocker encrypted USB disk can not only open in Vista, Win7 system, but also can be applied to the XP system. Do you find it troublesome to enter a password on your computer every time? It's easy to unlock it by simply checking the "Automatically unlock this computer from now on". In the future as long as U disk inserted into this computer, BitLocker will automatically unlock the trouble of manual input password. Of course, the automatic unlock here is only for this computer, on the other computer or will be protected by the key.

When you mention BitLocker, it's easy to associate yourself with the familiar EFS encryption, but the difference between the two is great. The focus of EFS is to protect a single file (folder) in which a user can encrypt a single file (folder). BitLocker, however, prefers to protect the entire drive, and without the correct password, you can't read any of the contents of the drive.
