Basic Cryptography # Sending Messages # Say, there are 3 people, Aditi, Bhaskar and Diti.
Aditi wants to send the message “HELLO” to Bhaskar, using her computer.
Computers, however, can only store numbers. How will she send the message “HELLO” to Bhaskar?
To store characters, there is a code called the ASCII code.
