Summary: The War of Codemakers & Codebreakers
Çetin Kaya Koç email@example.com
Since the time of Caesar or even earlier, people are interested
in "secret communications"
To hide the content of his messages from the enemy, Caesar
developed "an encryption method" = Caesar Cipher
For every letter in the word, replace the letter with the letter
3 locations ahead in the alphabet
a b c d e f g h i j k l m n o p q r s t u v w x y z
For example, if Caesar wants to send the order "attack", he
encrypts it as:
attack -> dwwdfn
and sends it to his General.
The enemy also captures the message and sees "dwwdfn".
But the enemy does not know what that means!!
