ALLENDALE, Mich. (May 6, 2014) — On May 5, the National Security Agency’s twitter account @NSACareers sent out this message:
Later that day, Szymon Machajewski, an affiliate instructor in Grand Valley’s School of Computing and Information Systems, explained how to solve the code in this YouTube video:
The first thing Machajewski noticed in the message was that the message was grouped into 12-character blocks. “We’re going to be dealing with a substitution cypher,” he says in the video. In the video, he explains where to get the online tools to help solve the code.
If you’re into puzzles, the video is worth watching.
And what did the NSA coded message say?
