Take a look at the following image. You should see two different ‘messages’ here.
This particular mish-mash of messages reflects the failure of otherwise strong cryptography: the improper implementation of a one-time pad or a stream cipher.

One-Time Pads
The one-time pad is the only encryption technique that has been mathematically proven to be uncrackable. While hard to use, it has often been the choice for highly sensitive traffic. Soviet spies used one-time pads in the 1940s and -50s. The Washington-Moscow “hot line” also uses one-time pads. However, the technique is hard to use correctly.
