Use the Syskey command to encrypt multiple data entries to ensure system security

Comments: Taking Windows XP as an example, there is a commonly used but powerful command in the system, that is, the syskey command. This command can effectively enhance your system security. Maybe you have to enter your account and password when entering Windows XP or Windows 2000, which is not safe. If your computer is used by many people, and others take Windows XP as an example, there is a general, but powerful command in the system, that is: syskey command. This command can effectively enhance your system security. Maybe you have to enter your account and password when entering Windows XP or Windows 2000, which is not safe. If your computer is used by many people, others can access the system by breaking the simple password of others, and exploit various vulnerabilities to gain administrator privileges. With the encrypted disk created by syskey, you can use Windows XP with full confidence. Next let's take a look at the usage of the syskey command.
I. Dual Password

1. Enter "syskey" in "run" in the Start menu and click "OK.

2. Click "Update" next. Because NTFS-related knowledge is used, it is recommended that the disk partition be in NTFS format.

3. Select Start password, enter a password, and then click OK. This will enable Windows XP to encrypt the password twice when it starts. When the operating system is started, a window will prompt "this computer requires a password to start before we enter the user name and password. Please enter the start password ". This is the first password protection we have just created.

Ii. Password floppy disk

1. if we select "Save Startup Password on a floppy disk", a password floppy disk will be generated. No one wants to access your operating system. of course, if you have set the syskey System Startup Password, you need to enter the password again to obtain the corresponding authorization. This dual protection makes the system operation safer.

2. Then, the system will prompt you to add a floppy disk to the drive. A prompt will appear after the password is generated.

3. Then we start the system again. Then, the system will prompt you to insert a password to the floppy disk. If you do not insert a floppy disk, click OK. The system will not allow you.

Insert a password floppy disk and enter different passwords based on different accounts. At the same time, if you want to, the key file in the password floppy disk can be copied to another floppy disk.

3. Restore the system

If one day you have less demanding security requirements on the operating system, and you are tired of inserting a floppy disk every time you enter the system, what should you do? Select "Save the start password on the local machine". Of course, you must have a floppy disk with a key, this is in line with the need to enter the authorization password when creating a password floppy disk. Originally, the syskey-encrypted system is already very secure, but there are still some methods to crack it. For this type of cracking, we must be optimistic about our machine, and we will not be able to give some people who are eager to start. At the same time, we can also use flash drive boot locks on the market to protect our systems. The main function of the boot lock is to prevent others from using your computer illegally, you can also set the lock time on your computer. Of course, this type of computer locks are also expensive and can be used by users with extremely high security requirements!
