The goal is to set up technological barriers to the National Security Agency's sweeping surveillance programs. Rather than waiting for Congress to rein in the agency, many people want to take privacy into their own hands.
But the truth is, efforts to improve online encryption and security can't totally thwart the NSA.
Joseph Lorenzo Hall, the chief technologist for the Center for Democracy and Technology, said the idea of becoming "NSA-proof" is "just silly."
"If they want it, they can get it," he said of the NSA's expert spies. The agency can hack or bypass many security measures if it is determined enough, Hall said.
