C++ CLI for folder encryption with AES-256-GCM and USB-based key loading
Summary
The Hacker News post highlights a Linux CLI tool that encrypts/decrypts folders using AES-256-GCM and can hide file/folder names, storing the mapping in an encrypted file, with the key loaded from USB. Community comments raise concerns about error handling, potential information leakage (e.g., file names), and the reliability of USB keys, suggesting caution and comparison to mature tools like CryFS. The project is linked to a GitHub repo (ACE-files-encryption) and appears to be a learning or experimental implementation rather than a battle-tested solution.
