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.

Encrypting with XOR: A Graphic Example
The exclusive or operation – a logical function applied to binary bits, like AND, OR, and NOT – is a fundamental encryption technique. It is often used in stream ciphers, which are widely used in web browsers when connecting to secure web servers.
Stream ciphers
Whenever your browser establishes a “secure” connection to a web site, it encrypts the data. The encryption often takes place byte-by-byte, since the software can’t always predict how much data will be sent. This encryption style requires a stream cipher.
