The Vigenère Cipher was adapted as a twist on the standard Caesar cipher to reduce the effectiveness of performing frequency analysis on the ciphertext. The cipher accomplishes this by using a text string (known as the keyword) as a key, which is then used to calculate a different alphabet shift for each letter of the plain text.
Enter the Keyword, enter your text and click either Decrypt or Encrpyt
