C++ CLI for folder encryption with AES-256-GCM and USB-based key loading

I built a Linux CLI tool that encrypts and decrypts folders using AES-256-GCM. It also hides file and folder names and stores the mapping in an encrypted file.

If this is a learning exercise, cool!

If this is a real thing, it needs a lot of work. Lots of failure modes, errors that are not being handled, sometimes exceptions, sometimes swallowing and printing to stdout, very inconsistent style, mixing and matching all kinds of C and C++ conventions...

I would recommend not using this for any data that you actually care about.

Why?

What does this solve the that the other far more mature tools don’t?

For example, has been around for decades. Is widely supported and battle tested.
