Encrypt text messages, files, or whole folders right in your browser. Share securely over
email, chat, or any cloud — nothing is ever uploaded to a server.
What this tool does
Three ways to lock — a typed password, any file used as a key, or a
proper public/private keypair (RSA or EC).
Generate keypairs in-browser — no command-line tools needed. Download
your private key and share the public one.
Upload whole folders — preview the file list, remove or rename anything
you didn't mean to include, then encrypt the cleaned-up archive.
Auto-detect on decrypt — paste an encrypted message or drop an .enc
file; we figure out which kind of key you need and only ask for that.
Everything stays on your device — no telemetry, no uploads, no
accounts. Close the tab and the keys are gone from memory.
