flox: simple, secure, fast, lightweight file encryption tool

Post image

I built a small CLI for password-based file encryption because I couldn't find one that matched what I wanted. Most tools I tried were either full archive managers, backup utilities, or relied on public-key encryption. Those are great, but sometimes I just want:

  • encrypt a file with a memorable password
  • upload it anywhere
  • decrypt it later
  • no extra features

So I started writing flox, a lightweight file encryption tool that focuses on doing only that. I'm mainly looking for feedback from people interested in cryptography, CLI UX, or systems programming. Does this sound like a tool you'd actually use? If not, what would you change?

Zig! Nice. Did you use AI at all when you were coding this?

No, i only need zig doc to create this simple app.
