Encryption Program

This is a desktop program written in Java that allows the user to encrypt and decrypt messages using the one-time pad (OTP) encryption technique. OTP is a secure encryption method that relies on a pre-shared key that is used only once.

Functionality

The program has the following features:

• A text field where the user can enter the message to be encrypted.
• A button that generates a random key of the same length as the message.
• The message and the key are converted to binary format.
• The binary message and key are combined using the XOR logical operator to generate the cipher.
• The cipher is converted to text and displayed on the screen.
• The user can decrypt the message by entering the cipher and the key, and clicking on a button.
• The original message is displayed on the screen.
• The program does not allow the user to verify the message again, as the key is valid only once.
• The user can exit the program by clicking on the close button in the top left corner of the screen.

To run the program, you need to have Java 8 or later installed on your system.
