说明
grub2-mkpasswd-pbkdf2 generates hashed passwords for protecting GRUB 2 bootloader configuration. The output hash can be used in grub.cfg to password-protect boot entries or the GRUB command line. PBKDF2 (Password-Based Key Derivation Function 2) provides strong protection against brute-force attacks by using multiple iterations and a random salt. The resulting hash is safe to store in configuration files.
参数
- -c, --iteration-count _COUNT_
- Number of PBKDF2 iterations (higher is more secure but slower)
- -s, --salt _LENGTH_
- Length of the salt in bytes
