To use this program run mainGUI. Then you can enter a series of messages. Click on the "add" button to add your message to the list. If you would like to see what your messages will be when Caesars Cipher encryption algorithm is applied to it, hit the "encrypt" button. You can also revert it back to plain text by clicking "decrypt". If you would like to delete a message that is being displayed, simply click on the message you would like to delete and then click the "delete" button.
Caesar's Cipher is a basic cryptographic algorithm that will essentially "hide" plain text. It does this by shifting each letter in a message encrypted, 3 letters to the left.
Here is an example:
With Caesars Cipher Encryption applied "Hello" becomes "Ebiil".

Cryptography serves as the backbone to a secure internet. Without cryptography, we would be subject to a wide range of malicious attacks over the internet. Could even argue that the internet would not be usable without it. It safeguards our data. There are many more cryptographic algorithms that beat Caesars Cipher out of the park and we can dive even deeper into hash functions like with the algorithm SHA-256, it's quite an interesting field.
This program implements a very basic cryptographic algorithm. Something that really doesn't have much use in the real world these days. That is why I made the linked list able to accept generic types and the Cryptography interface. In the future the next step is to apply a more complex algorithm, such as Vigenère cipher and more.
