Encrypt the password of GRUB using the grub-md5-crypt command of linux

Do not know how to use linux's grub-md5-crypt command to encrypt GRUB's password? In fact, it is not difficult to solve this problem. Let the editor take you to learn how to solve it. I hope you will gain a lot after reading this article.

MD5, a widely used cryptographic hash function, can produce a 128bit hash value (hash value) to ensure complete and consistent transmission of information. The principle of MD5 algorithm can be briefly described as follows: MD5 code processes the input information in 512-bit packets, and each packet is divided into 16 32-bit subgroups. after a series of processing, the output of the algorithm consists of four 32-bit packets, which will generate a 128-bit hash value after concatenating the four 32-bit packets.

Use the grub-md5-crypt command to add an encrypted password to the password of GRUB in MD5 format.

Syntax format: grub-md5-crypt [parameters]

Common parameters:

Reference example

Generate a MD5 encrypted password:

[root@linuxcool ~] # grub-md5-crypt

Edit the grub configuration file:

[root@linuxcool] # vi / etc/grub.confpassword-- md5 $1$ xdRKQ/$43ZXGkk1yziGE12Vlqgg71 Thank you for reading this article carefully. I hope it is helpful for the editor to share the use of linux's grub-md5-crypt command to encrypt the password of GRUB. At the same time, I also hope that you will support it, pay attention to the industry information channel, and find a detailed solution waiting for you to learn!
