This article mainly introduces "string generation command of Centos system user password". In daily operation, I believe that many people have doubts about the string generation command of Centos system user password. Xiaobian consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "string generation command of Centos system user password". Next, please follow the editor to study!
I have been watching puppet these two days, and I am going to use this to manage the addition, allocation and deletion of users under my system, but every time I use the system's passwd command to generate user passwords, it is a bit too troublesome to look for them on the Internet. You can use perl to generate the passwords saved by linux users in shadow and share them as follows.
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
At this point, on the "Centos system user password string generation command" is over, I hope to be able to solve everyone's doubts.
