FileSentinel is an open-source Python tool that helps users monitor folders for unexpected file changes. It creates a baseline using SHA-256 hashes and later compares the folder against that baseline to detect added, modified, and deleted files. It is designed as a beginner-friendly defensive security utility for students, small offices, and anyone learning basic file integrity monitoring.

...The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the encryption key and part of the data — and multiple equal-sized public chunks, each renamed to its SHA-512 hash and given a uniform timestamp to prevent metadata inference. A private filename conversion table preserves the concatenation order needed for restoration. Together these measures guarantee confidentiality, integrity, and availability regardless of storage provider trustworthiness. Threshold Key Sharing extends this further by splitting the private key, eliminating the single point of failure.

Midbar Firebase Edition - is the edition of Midbar that stores the encrypted data in the cloud while keeping the cryptographic keys on the device! It comes with the firmware for the hardware IoT data vault and the desktop app that's synced with the vault via the Google Firebase. A vault and an app can be used without one another.
