Fix Recommendation

Configure the operating system to store only SHA512 encrypted representations of passwords.

Add or update the following line in "/etc/libuser.conf" in the [defaults] section:

crypt_style = sha512

Check Contents

Verify the user and group account administration utilities are configured to store only encrypted representations of passwords. The strength of encryption that must be used to hash passwords for all accounts is "SHA512".

Check that the system is configured to create "SHA512" hashed passwords with the following command:

# grep -i sha512 /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.
