This program uses the Vigenere cipher to encrypt text messages using an encryption key determined by the user. From the main screen, The user can choose whether to encrypt or decrypt a message, enter his encryption key, and the program will present him the encrypted/decrypted message on a new textbox on the screen.

About The Cipher

The Vigenere cipher was issued in 1553. It is a polyalphabetic cipher, which uses a key to encrypt plaintext into ciphertext. The main advantage of it is that it is highly resistant to frequency analysis.

Implementation

The GUI design is based on three screens:

  • The menu screen - For the user to choose whether to encrypt or decipher a message.
  • The Encrypt screen - Encrypting the user's message.
  • The Decrypt screen - Decrypting the user message.

The program makes validation checks to determain if the user's input follows the key and message requirements. If any of the checks detect an error, a popup message apear on the screen.

The program also make sure the user saved the encryption key using a popup message.
