Check Text ( C-42327r1_chk )
Check all password hashes in /etc/passwd or /etc/shadow begin with '$5$' or '$6$'.

Procedure:
# cut -d ':' -f2 /etc/passwd
# cut -d ':' -f2 /etc/shadow

Any password hashes present not beginning with '$5$' or '$6$', is a finding.
Fix Text (F-38298r1_fix)
Change the passwords for all accounts using non-compliant password hashes.
