Demo: https://ChaosWebs.net/snow2

About

Snow2 is a web app inspired by the original snow program to use whitespace/zero-width characters to obfuscate messages within the whitespace of other content.

License

MIT license, see LICENSE file.

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
