RHEL-06-000064 - The system must use a FIPS 140-2 approved cryptographic hashing algorithm for generating account password hashes (libuser.conf) - libuser.conf.

Information

Using a stronger hashing algorithm makes password cracking attacks more difficult.

Solution

In '/etc/libuser.conf', add or correct the following line in its '[defaults]' section to ensure the system will use the SHA-512 algorithm for password hashing:

crypt_style = sha512
