About:
Kekkai is a command-line tool designed to monitor file integrity by tracking changes to specified files or directories. It works by calculating and storing checksums, then comparing them against the current state to detect any modifications. This provides a simple yet effective way to ensure that critical files have not been tampered with.

Key Features:

Calculates and verifies file checksums (MD5, SHA1, etc.)
Monitors specified files or directories for changes
Outputs detection results in a machine-readable format (JSON)
Simple command-line interface for easy integration

Use Cases:

Verifying the integrity of critical system files or application binaries
Detecting unauthorized changes to configuration files
Auditing file states before and after software deployments

Alternatives:

Tripwire – Tripwire is a more comprehensive enterprise-grade security tool, whereas Kekkai offers a lightweight, simpler approach for basic integrity checks.
AIDE (Advanced Intrusion Detection Environment) – AIDE is a powerful open-source alternative for file integrity checking, often with more complex configuration compared to Kekkai's straightforward usage.
