Question 2: ROT13 is an interesting encryption algorithm in that it has no key. It uses a form of the Caesar cipher to encrypt text. Try encoding a message by entering text in the box at http://www.rot13.com/. Exchange your encrypted message with someone else in class. Then enter their coded message you've received into the text box. The message will be revealed. If you apply ROT13 to the text message, it comes out encrypted. But if you re-apply the same ROT13 a second time to the encrypted message, it comes out decrypted. Now why would anyone use an encryption method that is so trivial to crack?
