Designed in a sort of game format, this program allows the user to encrypt and decrypt codes using the standard Vigenere Square Ciper.
The user inputs a string of letters and spaces they want encoded. They also enter a unique key that will be used as its complement on the table.
Each letter in each location in the user input and its corresponding letter in the key are compared on the Vigenere Square. The text input letters are searched for in the columns and the key input letters are searched for in the rows. Where the rows and columns meet on the table is the corresponding letter to the newly encrypted cipher. This process is repeated for every letter in the user input text and the cipher is built. (Note: The letters in the key are recycled as many times as necessary to match the length of the user input text)
