Task1: In this assignment you will decipher messages that are encrypted using two of the classical ciphers. You are encouraged to do them by hand first and resort to the tool available at the link provided below or other tools you find on the Internet to automate the process.

WHAT to submit For each cipher: Also provide answers to the following questions, reflecting on your experience with this assignment: Task2: In this assignment you are comparing hashes of some Strings using various Has function algorithms. Go to the sitehttp://www.fileformat.info/tool/hash.htm. Write a string in the string textbox and hit the hash button. Scroll down to see the hash though various algorithms. Copy and paste the hash values in a Word file. Make a small change in the string and hit the hash button again. Compare the hash values with those from the previous string. Note how quickly all the hashes were calculated. Note that a small change in input gives a drastically different hash value. Choose a file from your computer and calculate the hash of it on this site (Repeat the steps above on two different files). Write a paragraph or two about this experiment.
