Micah Lee gives us a wonderfully fascinating, long-form article covering his initial contact by Ed Snowden, the open source tools used and their subsequent communications and achievements.
The article, Ed Snowden Taught Me To Smuggle Secrets Past Incredible Danger. Now I Teach You. touches on security, tracking and encryption with just enough explanations to keep the non-technical readers understanding high without breaking the flow of the story.
As the story advances, so do the methods to avoid tracking and maintain anonymity on the Internet. The final reveal, a 30-page white paper on the open source tools used to communicate with Snowden, is an even longer read than the article. While the white paper is over a year old (with a note saying a revised edition is in the works), it looks like it could be interesting to peruse as well (I haven’t yet).
