# The LKDC is wanting for official documentation. Here's any bits of information I've found as of 20121113

The LKDC is used for local authentication for peer-to-peer services, specifically AFP file sharing, Screen Sharing 
and Back to My Mac.

redesigned, but here's a cached version)

At work recently I needed to pull together some information from the registry of a few thousand machines and include the last time the key had been updated. Lately I've been turning to Powershell more and more for my day to day tasks and this time was no different. However this simple task turned out to not be so easy, and it all revolved around acquiring the LastWriteTime of the registry keys.

Digging through WMI and .NET proved less fruitful than I had hoped, so off to Google I went. It seemed everyone had the solution if you wanted to query the machine locally, but with thousands of hosts in my Enterprise that wasn't going to work. Plus, who doesn't enjoy a good challenge. One particular script was very useful in pointing my team in the right direction, posted by Tim Medin over at blog.securitywhole.com. So we decided to adapt and modify his script to work with remote hosts.

I've only tested against a few machines at home, but I wanted to share it while I had time. I will update the post if I find issues

"""
Mac OSX Catalina User Password Hash Extractor

Extracts a user's password hash as a hashcat-compatible string.

Mac OSX Catalina (10.15) uses a salted SHA-512 PBKDF2 for storing user passwords
(hashcat type 7100), and it's saved in an annoying binary-plist-nested-inside-xml-plist
format, so previously reported methods for extracting the hash don't work.
