vigenere-cipher

This java program provides an implementation of the Vigenere cipher.

Description

The program accepts characters between ASCII numbers 33 (corresponds to '!') And 122 (corresponds to 'z').

Usage

java Vigenere <key> <input_file> <output_file>

The above execution encrypts the message in the input file based on the key and saves the encrypted message in the output file.

Example

java Vigenere QRSTUVWXYZ ./data/input.txt ./data/output.txt


Original text: ABCDEFGHIJKLMNOP

Encrypted text: qsuwy!#%')!#%')+

Decrypted text: ABCDEFGHIJKLMNOP

Encrypted and decrypted successfully!!!
