One time pads are the only information theoretically secure cipher. Of course, the devil's in the details. The key has to be truly random. There is the issue of key exchange. But, once you meet these requirements, there is no way to break a one time pad. All possible decryptions with the same length as the message are equally likely, so how do you know that you know that a given 6-letter string decrypts to "rob_au" vs "chester"?
