I couldn’t find a local Post-Quantum file encryption tool, so I built my own. Looking for feedback. Any thought on this ?

Hey everyone,

I’ve been searching for a dedicated post-quantum cryptography (PQC) tool to secure my local files against "harvest now, decrypt later" attacks, but couldn’t find a standalone tool that fit my threat model. So, I built one from one scratch.

I’ll admit I am a bit of a security paranoiac, but two things constantly bother me:

Cloud Backups: I don't trust providers like Google Drive or Microsoft OneDrive with unencrypted data. I need my files locked down locally before they ever touch the cloud.

Platform Interception: When sharing sensitive files over platforms owned by tech giants (who actively fund massive quantum research labs), I want a guarantee that they can't just harvest the data and brute-force it later.
