I want to develop an application which allows users to also communicate over the Tor network. I have done some Googling but I can't seem to find an API or SDK. How does one develop a Tor application? Are there any libraries out there?
EDIT: I see there are no libraries or API's available to use Tor. What would I need to know in order to write this Tor application?
This is how:
from https://stem.torproject.org/faq.html#what-is-stem
"Stem is a Python controller library that you can use to interact with Tor. With it you can write scripts and applications with capabilities similar to Vidalia and arm.
From a technical standpoint, Stem is a Python implementation of Tor's directory and control specifications. To get started see our tutorials!"
To my knowledge Tor does not have an actual API or SDK.
Tor does come with a SOCKS interface though. So the simplest way of making an app work over the Tor network is to use a SOCKS proxy with the default Tor installation on a user's computer.
For an example using Go, check out Pond.
