Is Blackbird Open Source?
Yes! Feel free to use the source code for your own needs or projects. Blackbird uses a very tricky “anonymous JavaScript callback” method to rewrite data of DOM elements right back into the document source. This alone is worth sharing. Keep in mind however that the “official” Blackbird system is maintained here. So if you make your own improvements or add encryption that you feel the project (and perhaps the world) will benefit from, please let us know about this and submit your changes so they may be included in the next version.
