Steganography example 1: Hello John Doe! another hidden message perhaps something like 'Viens à l'hotel à minuit comme d'habitude tu ne peux pas savoir comme j'ai envie de toi, comme j'ai envie que tu me prennes là, tout de suite.'How are you today? |

Steganography example 2: The smiley below has an embedded message. |

Steganography example 3: The following link is to a 3-second audio file. It says "Hello John Doe" when played. Please click on it to hear it for yourself. |

Cryptography
Secret writing, (the idea of hiding the meaning of a message) dates back to 19th century BC.
The trick is simple substitution. The catch is that when you do not know what to substitute with what, deciphering the message can become a real challenge. For eg. it would be very easy to see "12334" meant "HELLO", if only you knew 1 was H, 2 was E, 3 was L, and 4 was O. That is called "key". If you do not have the key, guessing the meaning of 12334 could be difficult, especially when the "text" is short. Contrarily, when there is a long essay to decipher, the human eye can easily see patterns and substitutions.
However, it is not that easy today. The demo below gives an idea.
