1. Decrypt the following message that was encrypted using a Vignere cipher. Your answer should be the key and the plaintext along with information on how you solved the problem. a. If you opt to write a small program to help you with this, you need to upload the code as part of your homework submission. b. If you do this by hand, you need to show all your work, including the iterations you went through to get the final plaintext. c. You CANNOT use some web program and just submit the plaintext and the key. No points will be given for that solution Remember, the Kasiski method is the easiest way to do this. Find the groups of characters that are repeated and then record the spacing between them. You start counting the letter after the first letter in the repeat and stop counting when you come to the first letter in the next repeat. You include that first repeated letter in your count. Then, see what the factors are to make those spacings (for example, 15, 5, 25 spacing between the repeated character sets might mean a key word size of 5). Then, look at the distribution for each letter at that indexed position to see if it matches the patterns found in the English language. Solve for the first character, the second, and so on until the words start to make sense
