So at this rate are there any encryption methods that we're pretty sure that the NSA cannot crack? By introducing such back doors, the N.S.A. has surreptitiously accomplished what it had failed to do in the open. Two decades ago, officials grew concerned about the spread of strong encryption software like Pretty Good Privacy, or P.G.P., designed by a programmer named Phil Zimmermann.
