<p>
|
|
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/example_encrypted.html">example</a>).
|
|
</p>
|
|
<p>
|
|
The tool is also available as <a href="https://npmjs.com/package/staticrypt">a CLI on NPM</a> and is <a
|
|
href="https://github.com/robinmoisson/staticrypt">open source on GitHub</a>.
|

|
</a>

|
</h4>
|
|
<div id="concept" class="hidden">
|

<p>
|
|
<b class="text-danger">Disclaimer</b> if you have extra sensitive banking data, you should probably
|
|
use something else!
|
|
</p>
|
|
<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 example)
|
|
and you're done: the javascript will prompt users for password, decrypt the page and load your HTML.
|
|
</p>
|
|
<p>
|
|
It 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/dictionary attacks would be trivial to
|
|
do at a really fast pace: use a long, unusual passphrase!</b>
