just released a small tool I’ve been working on called BitCache. It's designed to help backup and manage BitLocker recovery keys more easily. Here's the gist:

What it does:

Scans and backs up BitLocker recovery keys Entra ID

Saves them into a local database for easy access

Completely portable – no installation required

Open source (MIT license) – feel free to inspect, fork, or contribute

Why I built it: It may be used for storage and archiving but mainly it solves a problem I noticed - when a computer objects is remvoed from Entra ID, all BitLocker keys disappear. This may pose a problem if you need to unlock a volume on a computer that was in a storage for last 2 years.

Where to get it: pawellakomski/bitcache

Looking for testers & feedback: I'd love for others to try it out and let me know what you think. Whether it's feature requests, bugs, or thoughts on security/privacy – all feedback is appreciated.

You can also provide feedback to bitcacheteam@pm.me

Thanks for checking it out!
