Someday, theoretically, maybe. This means that, as far as everyone knows, if I properly secure a message to you using RSA, no one else is reading the message. Maybe in 50 years they can, but, well, that's in 50 years. Alarmists would have you believe it'll happen in three. I'm just an Internet rando, but my money's on it being closer to 50. Regardless though, it's not today.
