Fix Recommendation

Configure RHEL 10 to use the SHA-512 algorithm for password hashing.

Add or change the following line in the "[default]" section of the "/etc/libuser.conf" file:

crypt_style = sha512

Check Contents

Verify RHEL 10 user and group account administration utilities are configured to store only encrypted representations of passwords with the following command:

$ sudo grep crypt /etc/libuser.conf
crypt_style = sha512

If the "crypt_style" variable is not set to "sha512", is not in the defaults section, is commented out, or does not exist, this is a finding.
