Win7 system makes U disk more secure BitLocker encryption U disk technology

Now a 4GU disk is only a little more than a dozen dollars, it is really very cheap, and many users are used to carrying a U disk to store some files For some office workers, the U disk is like a virtual briefcase, which contains the materials needed for work and life. If the U disk with so much important information is accidentally lost, we lose at best. It’s just a dozen dollars, but the key issue is that if the files inside are accidentally leaked, then the loss is not a little bit. I won't take Mr. Chen's example here because you know. In fact, users who use the Win7 system have a very secure encryption tool. With it, you can safely encrypt the USB flash drive without worrying about the risk of being illegally cracked. This is the BitLocker encryption feature of the Win7 system. Therefore, the Win7 system can set the U disk encryption without any trace, making it a personal utopia.

In the Win7 system, the operation of encrypting the U disk with BitLocker is very simple. You only need to select “Enable BitLocker” in the right-click menu of the drive letter of the U disk to enter the BitLocker Encryption Wizard. The first is to choose the lock mode, the ordinary user can choose the password to unlock the way, remember to set the password must be a strong password to eliminate the possibility of brute force. The smart card unlocking method is only available to users who have a smart card.

(Smart card is a small plastic card with a computer chip. Smart cards are usually issued by the information technology (IT) department of a large company. To use a smart card, you also need a smart card reader, which is installed Or connect to a computer and can read the information stored on the smart card.

The next option is to save the recovery key. The so-called recovery key is actually a text file with a string of decrypted characters. You can use this string of characters to decrypt the U disk when the user forgets the password, so this file needs to be properly kept. If you confirm that you will not forget the encrypted password you set, you can delete the recovery key.
( When the computer boots, if BitLocker detects that a system condition may indicate a security risk, such as a disk error, a change to the BIOS, or a change to any startup files, BitLocker will lock the drive and require a specific BitLocker recovery password to unlock it. Make sure to create this recovery password the first time you open BitLocker; otherwise, you may permanently lose the file Access rights.) Recovery key saving option

The next step is the waiting time, waiting for the entire disk encryption operation to complete, the time it takes depends on the size and transmission rate of the USB disk. Don't worry, that is The time to enable encryption needs to be so long. The use of the encrypted U disk is the same as that of the U disk before the encryption. The user will automatically complete the encryption process when the file is stored in the U disk. This process is only a moment. And vice versa.
Wait for encryption to complete

So, how to use BitLocker encrypted U disk? In Win7 system, users only need to access the encrypted U disk, a decryption dialog box will pop up. After entering the password, you can unlock the U disk, and then you can use the U disk as usual. This is just the unlock operation in the current computer, not the decryption operation, that is, the file is automatically encrypted in the background after unlocking. (Files are stored in a USB flash drive) and decrypted (files are copied from a USB flash drive to the local).

If you don't want to enter your password every time, you can tick "> from now on. The option to automatically unlock on the computer will be automatically unlocked after inserting the encrypted USB flash drive in the computer.
Unlocking operation

U disk encrypted with BitLocker is not usable without decryption, even if it is given to others To, no password can only hope U disk sigh, the other party can only format the U disk operation. BitLocker encrypted U disk will open a WinXP system, will display a bunch of files, then users need to find BitLockerToGo this Executing the file and running it will open the BitLocker To Go reader. This reader is designed by Microsoft to decrypt the BitLocker encrypted USB flash drive for WinXP system. However, it should be noted that this tool can only help users to read the encryption. The files in the U disk cannot be modified or added to delete files.
