# Snow2
|
||||
|
||||
Obfuscate & Encrypt Text as White-Space
|
||||
|
||||
Demo: [https://ChaosWebs.net/snow2](https://chaoswebs.net/snow2/)
|
||||
|
||||
|
||||
|
||||
# About
|
||||
|
||||
Snow2 is a web app inspired by the [original snow program](http://darkside.com.au/snow/) to use whitespace/zero-width characters to obfuscate messages within the whitespace of other content.
|
||||
|
||||

|
||||
|
||||
# Warnings
|
||||
|
||||
* No steganography is perfect, your message may be discovered especially by skilled adversaries.
|
||||
* Some text editors (like vim) show zero width characters
|
||||
* Some clients/places may strip whitespace characters
|
||||
* Use encryption if you really need to protect your messages. Use a good password but keep in mind that no encryption is perfect (Snow2 uses cryptojs AES)
|
||||
* It is best to save the site offline to avoid your messages being intercepted by possible malicious code sent from (my) web server
|
||||
* The larger your message, the more obvious it is that it is there.
|
||||
|
||||
# Roadmap (to do)
|
||||
|
||||
* Ability to automatically spread/retrieve message content into paragraphs of "cover" text
|
||||
|
||||
* CLI version
|
||||
|
||||
* Android app

|

<h1>About</h1>
|
||||
<p>Snow10 is a free and open-source web and Android app for converting messages into invisible whitespace characters and back again.</p>
|
||||
<br>
|
||||
<img src='./snow.jpg' alt='snow image'>
|
||||
<br><br>
|
||||
<p><a href='https://github.com/beardog108/snow10/'>It is available on Github</a>.</p>
|
||||
<h1>Encoding Basics</h1>
|
||||
<p>Snow10 messages are meant to be embedded elsewhere, specifically within or by standard blocks of text.</p>
|
||||
<p>Messages with the 'zero width characters' setting work in most places that accept unicode input.</p>
|
||||
<p>Simply enter the message you want to hide <b>(waring: larger messages are more noticeable, and really massive messages may be dangerous/not work)</b></p>
|
||||
<p>You can uncheck 'use zero width characters' but this is more noticeable in some cases and is more likely to be stripped out.</p>
|
||||
<p>Then, enter a decent password in both passwords fields to encrypt your message (or disable encryption, but note that doing so will let anyone read your message.)</p>
|
||||
<p>Press 'encode' and wait for the output window to show, then, press 'copy to clipboard'.</p>
|
||||
<p>You can now paste your message inside Twitter DMs, social media posts, word documents, or elsewhere.</p>
|
||||
|
||||
<h2>Decoding Basics</h2>
|
||||
|
||||
<p>To retrieve a Snow10 message, copy paste it into the text field.</p>
|
||||
<p>It is important to get the full message, & if not using 'zero width characters', then remove any non-message text. <b>This can be difficult, but failing to do so many result in an incomplete or corrupted message.</b></p>
|
||||
<p>If the message is encrypted, enter the password (you only need to enter it into the first field to decode).</p>
|
||||
<p>If the message is not encrypted, uncheck 'use encryption'</p>
|
||||
<p>Then, press decode.</p>
|
||||
<p>If all went right, then you should see the decoded message.</p>
|
||||
|
||||
<h2>Example</h2>
|
||||
|
||||
<p>Here is an example of Snow10's use.</p>

||||

||||
