Based on the crypto-js library, StatiCrypt uses AES-256 to encrypt your string with your passphrase in your browser (client side).
Download your encrypted string in a HTML page with a password prompt you can upload anywhere (see example).
Disclaimer TL;DR: if you have extra sensitive banking data, you should probably use something else :)
StatiCrypt basically encrypts your page and puts everything with a user-friendly way to use a password
in the new file.
AES-256 is state of the art but brute-force/dictionary attacks would be trivial to do at a really fast pace: use a long, unusual passphrase !
The concept is simple but this is a side project - not purporting to be bulletproof, feel free to contribute or report any thought to the GitHub project !
