About hat.sh
hat.sh is a web application for encrypting and decrypting files. The work happens locally in the browser, so the file you pick is processed on your own machine rather than uploaded to a server for encryption.
It suits people who want to protect a file before sending or storing it, and who do not want to install a desktop encryption program. Because it runs in a browser tab, it works on any system with a modern browser.
