 # WiTTY: Web-based interactive TTY
-This program allows you to use terminal in the browser. Simply run the program and give it the command to execute when users connect via the browser. ___Interestingly___, it allows others to view your interactive sessions as well. This could be useful to provide remote support and/or help. You can use the program to run any command line programs, such as ```bash```, ```htop```, ```vi```, ```ssh```. This following screenshot shows that six interactive session running ```zsh``` on macOS Monterey. <img src="https://github.com/syssecfsu/witty/blob/master/extra/main.png?raw=true" width="800px">

 To use the program, you need to provide a TLS cert. You can request a free [Let's Encrypt](https://letsencrypt.org/) cert or use a self-signed cert. The program currently does not support user authentication. Therefore, do not run it in untrusted networks or leave it running. A probably safe use of the program is to run ```ssh```. Please ensure that you do not automatically login to the ssh server (e.g., via key authentication).
