Built for real security

Not another cloud wrapper. Flux-Tui is a proper cryptographic vault that runs entirely on your hardware.

01
🔐
AES-256-GCM Encryption

Industry-standard authenticated encryption. Every file gets a unique IV and is verified on decrypt — tamper detection built in.

02
scrypt Key Derivation

Your master password is hardened with scrypt N=2¹⁷ before any key is derived. Brute force is computationally infeasible.

03
🖥
Terminal-Native TUI

Full-screen terminal interface with hotkeys, themes, vault search, and an in-terminal editor. No GUI dependency.

04
📴
Fully Offline

Zero network calls. Ever. Your files never leave your machine. No syncing, no cloud, no exposure surface.

05
🔍
Integrity Verification

Startup vault scan cryptographically verifies every file. Tampered or corrupted files are flagged immediately.

06
🎨
20+ Themes

Phantom, Matrix, Ocean, Neon, Aurora and more. Full theme engine with animated colour palettes and rain effects.

Principles
Why Flux-Tui?
01

Your files stay yours

Cloud encryption tools can be subpoenaed, breached, or shut down. Flux-Tui has no server to attack — your vault is just files on your drive.

02

No backdoor. No master key.

We cannot recover your password. There is no reset flow, no recovery email, no escrow. If you forget it, the data is gone. That's the point.

03

Open source and auditable

Every line of code is public. Security through obscurity is not security. Read it, compile it, audit it yourself.

04

Free because privacy shouldn't cost money

No tiers. No subscription. No premium features. The full tool, forever, for anyone.
