|
|
Based on the <a href="https://github.com/brix/crypto-js">crypto-js library</a>, StatiCrypt uses AES-256
|
|
to encrypt your string with your passphrase in your browser (client side).
|
|
</p>
|
|
<p>
|
|
Download your encrypted string in a HTML page with a password prompt you can upload anywhere (see <a
|
|
target="_blank" href="example.html">example</a>).
|
|
</p>
|
|

<h4><a class="no-style" id="toggle-concept" href="#">HOW IT WORKS ►</a></h4>
|
|
<div id="concept" class="hidden">
|
|
<p>
|
|
StatiCrypt generates a static, password protected page that can be decrypted in-browser:
|
|
just send or upload the generated page to a place serving static content (github pages, for exemple)
|
|
and you're done: the javascript will prompt users for password, decrypt the page and load your HTML.
|
|
</p>
|
|
<p>
|
|
<b class="text-danger">Disclaimer</b> TL;DR: if you have extra sensitive data, you should probably
|
|
use something else :)
|
|
</p>
|
|
<p>
|
|
StatiCrypt basically encrypts your page and puts everything with a user-friendly way to use a password
|
|
in the new file.
|
|
<br>AES-256 is state of the art but <b>brute-force/dictionnary attacks are trivial to
|
|
do at a really fast pace: use a long, unusual passphrase !</b>
|
|
</p>
|
|
<p>
|
|
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 <a href="https://github.com/robinmoisson/staticrypt">GitHub
|
|
project</a> !
