A minimal, portable, fully in-browser encryption utility for plaintext messages.
Just-Encrypt-This (JET) was designed to be small, portable, and trust-less. Encryption happens in-browser, with nothing sent to a server. In fact, the entire application can be downloaded and used offline for both encryption and decryption by simply using "Save Page As..." — it's fully contained within a single, 32KB HTML file when compiled (11KB gzipped).
You can try it out live at jknotek.com/jet. If you're interested in reading the inspiration behind it, you can also take a look at this writeup.
It currently uses the popular SJCL encryption library for JavaScript. The plan is to move to the WebCryptoAPI when browser support eventually catches on... Perhaps as a fork rather than an upgrade.
The only build requirements are node and npm. The dependencies are specified
in the package.json file, and will be installed automatically using the steps
below.
After cloning the repository, cd into its directory and run the following:
-
npm install -
npm run build
And that's basically it. You will be left with a completely self-contained,
portable HTML file (dist/index.html) that can be moved around or uploaded to
your own server with no hassle.
