Linux Grub Password Settings

Grub password is divided into plaintext and ciphertext

1, clear text settings only need to be edited in the vim/etc/grub.conf file, the specific

2, ciphertext settings are divided into several types of encryption: now using Grub-md5-crypt to encrypt encryption, such as:

Copy the ciphertext generated by the dough into the/etc/grub.conf file, and then save the exit on it, such as:

There is another encryption algorithm: Grub-crypt--sha-256 encryption method.

Entering the Grub-crypt--sha-256 command at the command line, and then entering the password, produces a long string of characters, which is then added to the configuration file using the Passwor--sha.

Small White's experimental note, if you have any questions, please try to correct me. Thanks a lot!
