GEN000590 - The system must use a FIPS 140-2 approved cryptographic hashing algorithm for generating account password hashes - CRYPT_DEFAULT

Information

Systems must employ cryptographic hashes for passwords using the SHA-2 family of algorithms or FIPS 140-2 approved successors. The use of unapproved algorithms may result in weak password hashes more vulnerable to compromise.

Solution

Edit the /etc/security/policy.conf file.
# vi /etc/security/policy.conf
Uncomment or add the CRYPT_ALGORITHMS_ALLOW line and set it to '5,6'. Update the CRYPT_DEFAULT default line to be equal to 5 or 6. The following lines are acceptable.

CRYPT_ALGORITHMS_ALLOW=5,6
CRYPT_DEFAULT=6
