How to check if root password and grub password is same or not on RHEL 7 .

Hi I am trying to come up with a plan to write a script for syncing root password and grub password on RHEL 7.
If it was RHEL 6/5/4, I would simply compare shadow and grub.conf file,
but on RHEL 7 how can we acheive this. RHEL 7 uses grub2.cfg and their hash are different. Is there any other way I can accomplish this ?
Need a way to compare root and grub password and change if required ?

Thanks

This points to the source of a little program included with Samba. It is a pam plugin and will allow you to trigger an action whenever a password is changed. It should be easy to adapt it to change the grup2 password rather than the Samba database.

Hello,
If passwords were hashed with the same method, identical hashes would mean identical passwords. AFAIK, in the case of different hash methods, there is no way to find matches between passwords as the hash is meant to not having the ability to retrieve the password from the hash.

Thanks for the response guys. I also feel the same, it is not an easy task as hash value are different. I am researching methods if I can incorporate Melanie's suggestion and implement it.

Thanks again.
