In this issue, the editor will bring you about how to use shadow commands to generate user password strings in the Centos system. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

Perl-e'print crypt ("88991026", Q ($1$ aCwLBNGo)), "\ n"'\ where 88991026 is the password to be set for the user, $1$ aCwLBNGo string is a custom string, and the format $1$ followed by 8 characters is usually used in shadow.

The password string generated is as follows:

$1$ aCwLBNGo$0napSn3Qck9Sj4FqP5RFz0

There is a $in the middle, with salt in front of it, and the encryption value at the end, which is called hash.

Crypt itself defaults to des algorithm.

Use the md5 algorithm if salt starts with $1 $

The des algorithm commands are as follows:

Perl-e'print crypt ("88991026", "/ g"), "\ n"'

The password string generated is as follows:

/ gSr78Mzt1eYI
