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?

Implement the one-time pad encryption scheme in Microsoft Excel. Your worksheet should look as follows: For Encryption: - Have the message occupy adjacent cells in one row, with one bit of the message in each cell. Align the key (the one-time pad) with the message in the next row. Note that the key should be of the same length as the message. In the next row, enter a formula that computes the ciphertext. Decryption is similar: - Have the ciphertext occupy adjacent cells in one row, with one bit of the ciphertext in each cell. Align the key (the one-time pad) with the ciphertxt in the next row. Note that the key should be of the same length as the ciphertext. In the next row, enter a formula that computes the plaintext (message). .
Write a complete interactive program that displays the alphabet on the canvas. • Each time the user presses a letter key, the matching letter should get a little big bigger. • When the user presses the ENTER or RETURN keys (you can use Processing's RETURN and ENTER values to detect this), the letters should be reset to their initial size Make sure your program doesn't crash if a non-letter key, like a number or punctuation, is pressed. Hint: You might be tempted to do this "the long way", with 26 different variables and 26 if/elif statements under your keyPressed( function. Don't do that. Use a dictionary to store the count/size of each letter. If you do this nicely, your code will be short. Our solution is only 29 lines (including blank lines and function headers!).

Execute using JavaSwing GUI Jframe and Timer In your interface, provide a label and 3 buttons, and a timer. Initially, your label will display number 0. When first button is clicked, the number will increment by 1 and will be displayed for every 500ms. When second button is clicked, the number will decrement by 1 and will be displayed for every 500ms. The third button will start, stop the timer.

In python: The program should ask users for their email address and password for connecting to the mail server. You can create a new gmail account and use it for this assignment. Once the connection is complete, the program should ask for the receiver''s email address, and lastly send the email. Write "Hello" for the subject and "Email from Python" as body. Use the getpass library to hide password from shell. Instantiate an object and call it. Submit the .py file as well as screenshots showing the code runs and email received.
Write a Java Servlets program for calculating the total number of hits on a web pagedesigned by you. The web page should contain at least one title, one label and one output tag which displays the result of the calculation i.e. the number of hits on that page. The number of hits should be counted only for the one lifecycle of the servlet. Note that the program should have the comments embedded in it to explicitly explain why that code is being used.
