Caesar's code

Did you know that secret codes to endrypt messages already existed in Julius Caesar's time?

When he was at war in Gaul, the great roman General sometimes had to write to his officers to pass on instructions for the next assault. But it was very important that these instructions remain in Roman holding and don't end up in Gallic hands, the surprise effect being a key aspect of these instructions!

Suetonius, a roman historian who wrote the story of Julius Caesar, tells us that the General used a special system to code his messages.

Today, this system is called "Caesar's code" or "Caesar's cypher", in his honor.
