How to generate a rootpw password in Linux kickstart

In Linux KickStart, The rootpw password can use plain text or encrypted values (the password is ippbxadminroot)

Note: The encrypted value must be used here, otherwise the security will be too low.

Rootpw -- iscrypted $1 $ ippbxadm $ qlbcgdsck/a.1zzfek/mt.

The encrypted value is read, but how is this value generated?

This is the same as the password shadow in Linux. The generation method is as follows:

Perl-e 'print crypt ("ippbxadminroot", Q ($1 $ ippbxadm), "\ n "'

When special characters are used, for example, the @ $ character must be prefixed with \, for example, \ @ \ $. Otherwise, the encrypted string will be incorrect;

# Ippbxadminroot indicates the password to be set for the user. $1 $ ippbxadm is a custom string. Generally, $1 $ is followed by 8 characters in shadow.

The style of the generated password string is as follows:

$1 $ ippbxadm $ qlbcgdsck/a.1zzfek/mt.

There is a $ in the middle. The preceding value is salt, and the encrypted value is called hash together.

Crypt uses des by default.Algorithm

If salt starts with $1 $, the MD5 algorithm is used.

The DES algorithm command is as follows:

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

The style of the generated password string is as follows:
