Hello again earthlings. The fatmin returns once again to dispense a bit of wisdom. This handy one-liner is a command that for the life of me I cannot remember.
Our story begings when building your kickstart config and post-install config files you are going to need to set the password for at least one user (being root). If you are like me your configs add all sorts of users. As you know you cannot just stick the password for these users into your config files in plain text, rather you need to encrypt them via ssl.
The command to do so is below.
openssl passwd -1
At this point you will be prompted to enter the users password — twice. Then the command will spit out your ssl encrypted password which you can then shove into your config files.
