It's fast, secure and Serverless, the app never uploads the files to the server.
in a small amount of code the app can encrypt any type of files at any size within seconds.
To use the app all you have to do is Browse a file , Type a Decryption Key or Generate one through our secure key generator . and your encrypted file is ready to download.
(password-based key derivation)
deriving a cryptographic key from the given password using the PBKDF2 algorithm which is executed 100k times
combining the password entered and a password-based salt and the iterations
to create a cryptographic key
loading the selected file content and running the encryption algorithm with the derived cryptographic key in combination with a number used once to implement randomised encryption
NO. hat.sh never stores any files or passwords, it all happens locally in your browser.
YES. hat.sh is free and always will be, we depend only on donations
it's very simple, browse a file, generate a key or type one, click the button!.
No, the app accepts any type at any size.
Yes, the app encrypts the file using the AES-GCM algorithm
provided by the Web Crypto.
everything is done offline in your browser. No data is going to be sent to any server
NO as mentioned above, we don't keep any data. once you encrypt a file make sure to save the Key.
Hat.sh is an open-source app, it's currently in the beta version, you can help making it better by commiting. it's maintained only in the free time , Will appreciate your help by donating.
