Customers of Silent Circle’s encrypted mail service got an unfortunate surprise on Friday: all their messages had been deleted.
The management of Silent Circle, an encryption firm that specializes in smartphone communication, abruptly shut down their e-mail service yesterday, saying they were pre-empting the U.S. government from forcing them to hand over customer data. While they were confident they could protect text messages, voice calls and video calls, e-mail had always been less secure because it relied on standard Internet protocols. Yesterday’s catalyst was a competitor, Lavabit, whose founder announced he was shutting his email-hosting company down due to an apparent government investigation, and told Forbes on Friday: “If you knew what I knew about e-mail, you might not use it.” Edward Snowden had been a Lavabit user.
