Consolidated duplicated helpers into Elysium.Common.ps1: - Settings parsing (Read-KeyValueSettingsFile, Read-ElysiumSettings, Get-SettingsValue) - Azure Blob URI builder (Build-BlobUri) - S3 SigV4 signing helpers and AWS module bootstrap - AD credential validation and replication permission pre-check - Parallel execution helper (Get-FunctionDefinitionText) Test-WeakADPasswords.ps1 and Extract-NTHashes.ps1 now import Elysium.Common.ps1 for the first time. Update-KHDB.ps1 and Prepare-KHDBStorage.ps1 removed their local duplicates. Deleted legacy Settings.ps1 (superseded by ElysiumSettings.txt). Removed stray placeholder comment in Elysium.ps1. All versions bumped to unified v2.2.1.

.SYNOPSIS
|
|
Weak AD password finder component of Elysium tool.
|
|
|
|
.DESCRIPTION
|
|
This script will test the passwords of selected domain (defined in ElysiumSettings.txt) using DSInternals' Test-PasswordQuality cmdlet. It writes its output to a report file which is meant to be shared with the internal security team. The report now includes UPNs for each account mentioned.

1. Run this script from a dedicated non-FIPS workstation/jump host.
