What is the Autokey Cipher?
It is one of the encryption techniques.

Who it works?
For example, the key is alphabet( categorical not numeric), So if the entered key is “mo” and the plain text is “hussein” thenwe must complete by the plain text the key until it matches with the length of the plain text. In our example the key must be “mohusse” and the message is “hussein”.
