Fix Recommendation

Configure RHEL 8 to encrypt all stored passwords.

Edit/Modify the following line in the "/etc/login.defs" file and set "[ENCRYPT_METHOD]" to SHA512.

ENCRYPT_METHOD SHA512

Check Contents

Verify that the shadow password suite configuration is set to encrypt password with a FIPS 140-2 approved cryptographic hashing algorithm.

Check the hashing algorithm that is being used to hash passwords with the following command:

$ sudo grep -i crypt /etc/login.defs

ENCRYPT_METHOD SHA512

If "ENCRYPT_METHOD" does not equal SHA512 or greater, this is a finding.
