BitLocker is set to Win7 to give your U disk encryption

. In this article, we will introduce you to a small application of Win7 system, which is to encrypt your U disk. U disk is a kind of mobile device that we often use. Now most of the capacity is 8GB or 16GB, and higher, the price can be said to be very cheap. However, the U disk saves important files. The first is the loss of the U disk, and the second is the privacy of the file, which brings us some hidden dangers, so that we can't put a particularly important file on the U disk with a large capacity.

In fact, this is very simple, encryption is not enough? ! Yes, we don't need to spend more money to buy a professional fingerprint recognition U disk, nor to buy professional encryption software, as long as you use Win7 system, you can encrypt your U disk, the same can play a protective role, this is Win7 BitLocker encryption in the system.

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.

Establishing an encrypted USB flash drive

The first step is to select the lock mode. The normal user can choose the password unlock method. Remember that the password must be a strong password to prevent 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.)

Unlock mode

Next is the option to save the recovery key. The so-called recovery key is actually A text file, inside which is a string of decrypted characters. When the user forgets the password, the string can be used to decrypt the U disk. Therefore, this file needs to be properly kept. If you confirm that you will not forget the encrypted password you set, you can restore it. The key is deleted.

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

Recovery key save option

The next step is the waiting time for a period of time. Waiting for the entire encryption operation of the USB flash drive to complete, the time it takes depends on the size and transmission rate of the USB flash drive. Don't worry, it takes a long time 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.

How to use encrypted USB flash drive?

So, how to use BitLocker encrypted U disk? Under the Windows 7 system, the user only needs to access the encrypted U disk, and a decryption dialog box will pop up. After entering the password, the U disk can be unlocked, and then the U disk can be used as usual. 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 be automatically unlocked.

Unlocking Operation

U disk encrypted with BitLocker is not usable without decryption. Even if you get it to others, you can only expect U disk without password. I am sighing, what the other party can do is just format the U disk operation.

BitLocker encrypted U disk will display a bunch of files when opened under Windows XP. At this time, 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.
