Want to protect privacy, Win 7 makes U disk encryption easier

        Today's U disk and other mobile storage is really a cabbage price compared to a few years ago, a 4GU disk is only a few tens of dollars, many users are used to bring a U disk as a file transfer station between home and company, but this A small U disk is very easy to lose. There is a memory that is valuable and the data is priceless. It doesn't matter if the U disk is lost, but the important information files inside are taken away by people with ulterior motives.

In order not to leak important data, many users have turned to a variety of U disk encryption tools, but the U disk encryption tools on the market are uneven, some even pseudo-encrypted, there are The user's file loss due to design flaws, so that users are not worth the loss, is there a safe encryption tool?

In fact, users who use Windows7 have a very secure encryption tool, use it, You can safely encrypt your USB flash drive without worrying about the risk of being illegally cracked. This is the BitLocker encryption feature of Windows 7.

The operation of encrypting a USB flash drive with BitLocker in Windows 7 is very simple. You only need to select “Enable BitLocker” in the right-click menu of the drive letter of the USB flash drive to enter the BitLocker Encryption Wizard.

The first choice is to lock the way, 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.

(A smart card is a small plastic card containing 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 that is installed Or connect to a computer and read the information stored on the smart card.)

Next is the option 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.

(BitLocker will lock the drive if it detects a system condition that may indicate a security risk when the computer starts up, such as a disk error, a change to BiOS, or a change to any startup files And you need to use a specific BitLocker recovery password to unlock it. Make sure to create this recovery password the first time you open BitLocker; otherwise, you may lose access to the file permanently.)

Next is a paragraph The waiting time of the time, waiting for the entire encryption operation of the U disk to complete, the time taken depends on the size and transmission rate of the U disk. Don't worry, it takes so long to open the encryption. The U disk that is encrypted is the same as the U disk before the encryption. When the user saves the file to the USB flash drive, the encryption process is automatically completed. This process is only a moment, and vice versa.

So, how to use BitLocker encrypted U disk? In Windows7 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 USB flash drive and then use the USB flash drive as you normally would. This is just an unlock operation performed on the current computer, not a decryption operation. That is to say, after unlocking, the file encryption (file storage into the U disk) and decryption (copying the file from the U disk to the local) are automatically performed in the background.

If you don't want to enter your password every time, you can check the "Automatically unlock on this computer from now on" option. After inserting the encrypted USB flash drive in your computer, it will automatically Unlock.

U disk using BitLocker encryption is not available without decryption. Even if you get it to someone else, you can only hope that the U disk will be sighed without a password. The other party can only format the U disk.

BitLocker encrypted U disk will display a bunch of files when opened under Windows XP. This is, the user needs to find the executable file BitLockerToGo and run it, it will open BitLocker To Go reader, this reading Microsoft is designed specifically for users to decrypt BitLocker encrypted USB flash drives in Windows XP, but it should be noted that this tool can only help users to read files in encrypted U disk, but can not modify or add deleted files.
