Xiaobian to share with you the use of linux grub-crypt command password encryption, I hope you read this article after the harvest, let us discuss it together!

The purpose of the grub-crypt command is to encrypt passwords. The grub-crypt command supports MD5 and SHA encryption of passwords, and SHA-512 encryption of passwords by default.

SHA is the abbreviation of Secure Hash Algorithm, Chinese for secure hash algorithm, is a series of cryptographic hash functions designed by the National Security Agency of the United States and published by the National Institute of Standards and Technology of the United States. As SHA-1 has become less secure, SHA-2 versions have become mainstream.
