Today The New Yorker unveiled Strongbox, a service that allows sources to share information with TNY journalists securely and anonymously. As explained in this infographic, Strongbox relies on the Tor network, a dedicated server, PGP encryption, VPNs, and multiple laptops and thumb drives to prevent files from being intercepted or traced. The codebase, which is open source, was designed by the late Aaron Swartz (Previously). Kevin Poulsen, one of the organizers of the project, chronicles how Swartz developed the code and how the project managed to carry on after his death. TNY hopes that Strongbox will help the magazine continue its long tradition of investigative journalism.
