this is a javascript app that provides secure file encryption using the AES-256-GCM algorithm from WebCryptoAPI included in your browser. It's fast, secure and client-side, the app never uploads the files to the server. the app can encrypt any type of files.
Hat.sh is a web app that provides secure local file encryption in the browser. It's fast, secure, and uses modern cryptographic algorithms with chunked AEAD stream encryption.
Super clever app, I'm glad the documentation is online for extra credibility. I wish the link to the git was included on the site itself for more credibility, though.
