Wallet‑locked, local encryption for your files.
No servers. No tracking. No compromises.
Your wallet signature becomes your personal AES‑GCM key.
Files never leave your device. Everything happens in‑browser.
The AstroDev Encryption Tool is designed with one priority: your data stays yours. No servers. No uploads. No hidden storage. Everything happens directly on your device.
Your encryption key is generated from a one‑time wallet signature. We never see your private key, and the signature never grants permissions or costs gas.
Files never leave your computer. All encryption and decryption happens inside your browser using the Web Crypto API — the same cryptography trusted by modern browsers and operating systems.
We don’t store your files, keys, signatures, or metadata. When you close the page, everything disappears. Your privacy isn’t a feature — it’s the foundation.
Your files are encrypted using AES‑256‑GCM, a modern, authenticated encryption standard used by governments, banks, and security‑critical systems worldwide.
There’s nothing to sign up for and nothing to trust. The tool runs entirely in your browser — not on our servers.
Every part of the tool runs client‑side. Developers can inspect the code directly in the browser to verify exactly how it works.
