This encrypted messaging app could be a nightmare for the NSA

The NSA is not thrilled about the fact that encrypted communications are becoming easier and more widespread than ever before. Its director, Admiral Mike Rogers, said as much last week during a cybersecurity event in Washington, D.C., where he joined the FBI in asking for a “legal framework” by which government agencies can insert backdoors into commonly used communications software. So chances are, NSA and co. are not going to like Si​gnal, a cross-platform app that now lets you send encrypted text, picture and video messages to virtually anyone with a smartphone. The free app is made by Open Whisper Systems, makers of TextSecure and Redphone, which allow Android users to send end-to-end encrypted texts and calls, respectively. That means that short of someone hacking your phone and stealing your encryption keys, no one—not even the app’s creators—can eavesdrop on your calls and texts.
