The real chela web app is embedded below - the exact same build you can download
from the releases page, running entirely in your browser. Split a throwaway secret,
recover it, and see the words it produces. It works offline; nothing you type leaves
this page.
⚠ For demonstration purposes only
Do not put a real secret into the demo below. A page loaded from
the internet can be tampered with in transit, and a browser extension or other
script could read what you type. Use it to learn the flow with a fake secret -
nothing more.
For real use, run chela offline:
Download the signed chela.html from the
releases page.
Verify its minisign signature against the public key in the
README,
so you know the file wasn't altered.
Open it on a computer that is offline - ideally one that has never been online
(an air-gapped machine, or one booted from a live USB).
Open it in a private browser window with no extensions installed - a browser
extension can read anything on the page, including your secret.
Split or recover there, print or write down the shares, then close the page.
The threat model explains exactly what
the browser can and cannot protect.
