generate kickstart passwords

Synopsis

Generates kickstart-compatible syntax by default.

      $ pwkickstart
      Password:

      # md5
      rootpw --iscrypted $1$SI$D964QyK1.Iz/
      # sha256
      rootpw --iscrypted $5$Ll/Q6$SEYqHGso3maNbtBc1wjyiyr2
      # sha512
      rootpw --iscrypted $6$MN7wS$1QE3FmSBrN71tXV8y.Blif1avdhTYt/

Description

Utility pwkickstart generates kickstart passwords from password input and prints them to standard output in three different formats: md5, sha256 and sha512.

Previously grub-crypt provided the same, but it is not longer available in some Linux distributions.

The output in section was shortened to fit on screen in the SYNOPOSIS example above.

NON-INTERACTIVE MODE

The utility accepts exactly one parameter - the password. Entries are sorted from oldest to newest.

  $ pwkickstart mypass 
  $1$6FrN7YsS$2o3lfiD9T4LlUfKBgCe0X1
  $5$S2Zab0elQkL7fN.ikw.jmZeb7qtEK7DJESPDv9
  $6$slYmPDc8PtwOPmnx$9u3X3NE73XxuU7.5YlJAm/QMEahzx

To get the "strongest" possible hash:

  $ pwkickstart mypass | tail -n1
  $6$slYmPDc8PtwOPmnx$9u3X3NE73XxuU7.5YlJAm/QMEahzx

Grep exactly what's needed:

  $ pwkickstart mypass | grep '$6$'
  $6$slYmPDc8PtwOPmnx$9u3X3NE73XxuU7.5YlJAm/QMEahzx
