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

| V-22303 | GEN000590 | SV-40776r2_rule | Medium |
| Description |
|---|
| 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. |

| Verify the traditional UNIX crypt algorithm is deprecated. # egrep CRYPT_ALGORITHMS_ALLOW /etc/security/policy.conf If CRYPT_ALGORITHMS_ALLOW is not set, is not set to "6", or is not set to "5,6", this is a finding. Verify new password hashes are generated using either the SHA-256 or SHA-512 cryptographic hashing algorithm. # egrep CRYPT_DEFAULT /etc/security/policy.conf If CRYPT_DEFAULT is not set or is not equal to 5 or 6, this is a finding. |

| 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 |
