# Rule ID: RHEL-06-000063_rule
# Severity: medium
# Rule Version (STIG-ID): RHEL-06-000063
# Rule Title: The system must use a FIPS 140-2 approved cryptographic 
# hashing algorithm for generating account password hashes (login.defs).
#
# Vulnerability Discussion: Using a stronger hashing algorithm makes 
# password cracking attacks more difficult.
#
# Responsibility: 
# IAControls: 
#
# Check Content:
#
# Inspect "/etc/login.defs" and ensure the following line appears: 

# ENCRYPT_METHOD SHA512


# If it does not, this is a finding.
#
# Fix Text: 
#
# In "/etc/login.defs", add or correct the following line to ensure the 
# system will use SHA-512 as the hashing algorithm: 

# ENCRYPT_METHOD SHA512
