Add or update the following line in the "/etc/login.defs" file:

ENCRYPT_METHOD SHA512

Check Contents

Verify RHEL 10 is configured so that the shadow file stores only encrypted representations of passwords with a hash value of SHA512 with the following command:

$ sudo grep -i encrypt_method /etc/login.defs
ENCRYPT_METHOD SHA512

If "ENCRYPT_METHOD" does not have a value of "SHA512", or the line is commented out, this is a finding.
