Description

This module collects credentials and setup information
from Tenable Security Center. root or TNS user permissions
are required. We don't utilize SC's builtin backup
functionality as that requires SC to be shut down.
The module works in 2 phases:

Phase 1: gather all passwords which can be decrypted. These
are non-user ones such as credentials used for scans, creds
for the Nessus servers, SMTP, etc.

Phase 2: handle hashed passwords processing. SC uses SHA-512
and PBKDF2 according to the documentation, but the implementation
(salt+hash vs hash+salt) is unknown due to the source code being
protected by SourceGuardian. To get around this, we use a php
script on server to brute force the passwords. Note this will
use SC's resources. The crack attempt rate is ~6/sec on a test
instance, so you'll want a small password list.

Tested against SC 6.7.2 on RHEL9
