File encryption with no installation required
‘No installation required’ usually means ‘we hid the installer’. Elba means it literally: there is no installer, no admin prompt, no system service, no registry key. You copy one HTML file and run it.
Works on locked-down machines
Corporate laptops, university machines, and library computers often refuse installers. Elba runs anyway because there is nothing to install — the browser opens an HTML file.
Nothing to uninstall
Delete the file. Empty the trash. Done. There is no leftover cache to hunt down.
Questions people actually ask
- Do I need admin rights?
- No. Elba runs from a folder your normal user can read.
- Where does it store settings?
- Nowhere. Elba has no settings, no config file, and no local storage outside the folder you seal.
Take the island
Elba is one HTML file. It runs locally in a Chromium browser, seals a folder with AES-256-GCM, never phones home, and becomes open source on 1 January 2030.
