Introduction to the project:
The Vigenere cipher is a cipher based on using successively shifted alphabets, a different shifted alphabet for each of the 26 English letters.
The carried out task: Writing a program in Java that ciphers and deciphers messages. The system will take a text file, a keyword, and the desired operation (ciphering or deciphering) as inputs from its user. The output of the system consists of the creation and display of original and ciphered/deciphered files.
