Vigenere Cipher is a method of encrypting alphabetic text. It uses a simple form of polyalphabetic substitution. A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The encryption of the original text is done using the Vigenère square or Vigenere table. When the vigenere table is given, the encryption and decryption are done using the vigenere table (26 * 26 matrix) in this method.
