Use Ruby to Generate your Shadow Password

I was initially stumbled on creating the shadow compatible SHA-512 hash.
After a little research, the answer was obvious:

require 'digest/sha2'

password = "pass@123"
salt = rand(36**8).to_s(36)
shadow_hash = password.crypt("$6$" + salt)

And you now have a password hash which you can directly use in /etc/shadow
