Overvicw Vigenere cipher: In order to defeat a simple letter frequency analysis, the Vigenere cipher encodes a letter into one of several cipher letters, depending on its position in the input document. Choose a keyword, for example TIGER Then encode the first letter of the input text like this: RS The encoded alphabet is just the regular alphabet shifted to start at T, the first letter of the keyword TIGER. The second letter is encrypted according to the following map JIK M NO P W X Y Z GH The third, fourth, and fifth letters in the input text are encrypted using the alphabet sequences beginning with characters G, E, and R, and so on. Because the key is only five letters long, the sixth letter of the input tex is encrypted in the same way as the first. Write a program that encrypts or decrypts an input text (e.g. "attack at dawn") according to this cipher, using "falcon" as cipher key The following is a sample run of the Page 1 457 words + 100% 9:06 AM Type here to search 8/28/2018
