I've developed Sentinel Data, a CLI security tool designed to address a gap in standard encryption: the "authorized user, unauthorized context" risk.

Most Data Loss Prevention (DLP) systems fail when a session is already active or if a device is physically moved. Sentinel Data binds file decryption to the specific machine's hardware and environment. I created a short technical demo and an attack simulation to show how the tool blocks access when the environment is tampered with.

I'm looking for technical feedback on this implementation and would love to discuss the cryptographic binding logic with the community.

Looking forward to your thoughts!
