Webogram – UNOFFICIAL Telegram Web App

Telegram offers great apps for mobile communication. It is based on the MTProto protocol and has an Open API. I personally like Telegram for its speed and cloud-support (that makes a web app possible, unlike in the case of WA and others).

MTProto data can be carried over HTTP, but no official web-version for Telegram exists for the time being. So this project is my take at creating one.

Disclaimer: This is an alpha version of the Telegram UNOFFICIAL web application. It may have undetected security issues, and there is definitely a load of bugs to fix, features to add and so on. So if you want 200% secure and fully functional communication, don't use this yet! You can always find Telegram official mobile applications here: https://telegram.org

That said, I'm using this app myself and I'd like to share its sources, so anyone can contribute to the development. Any help is welcome!
