Lately, Mike Janke has been getting what he calls the “hairy eyeball” from international government agencies. The 44-year-old former Navy SEAL commando, together with two of the world’s most renowned cryptographers, was always bound to ruffle some high-level feathers with his new project—a surveillance-resistant communications platform that makes complex encryption so simple your grandma can use it.
This week, after more than two years of preparation, the finished product has hit the market. Named Silent Circle, it is in essence a series of applications that can be used on a mobile device to encrypt communications—text messages, plus voice and video calls. Currently, apps for the iPhone and iPad are available, with versions for Windows, Galaxy, Nexus, and Android in the works. An email service is also soon scheduled to launch.
The encryption is peer to peer, which means that Silent Circle doesn’t centrally hold a key that can be used to decrypt people’s messages or phone calls. Each phone generates a unique key every time a call is made, then deletes it straight after the call finishes. When sending text messages or images, there is even a “burn” function, which allows you to set a time limit on anything you send to another Silent Circle user—a bit like how “this tape will self destruct” goes down in Mission: Impossible, but without the smoke or fire.
Silent Circle began as an idea Janke had after spending 12 years working for the U.S. military and later as a security contractor. When traveling overseas, he realized that there was no easy-to-use, trustworthy encrypted communications provider available to keep in touch with family back home. Cellphone calls, text messages, and emails sent over the likes of Hotmail and Gmail can just be “pulled right out of the air,” according to Janke, and he didn’t think the few commercial services offering encryption—like Skype and Hushmail—were secure enough. He was also made uneasy by reports about increased government snooping on communications. “It offended what I thought were my God-given rights—to be able to have a free conversation,” Janke says. “And so I began on this quest to find something to solve it.”
