Activity 1 Symmetric Encryption using Vigenere Cipher1. Click on File from the menu and select New.2. Enter (paste) the following text in the window:On September 25, 1789, the First Congress of the United States proposed 12 amendments to the Constitution. The 1789 Joint Resolution of Congress proposing the amendments is on display in the Rotunda in the National Archives Museum. Ten of the proposed 12 amendments were ratified by three-fourths of the state legislatures on December 15, 1791. The ratified Articles (Articles 3–12) constitute the first 10 amendments of the Constitution, or the U.S. Bill of Rights. In 1992, 203 years after it was proposed, Article 2 was ratified as the 27th Amendment to the Constitution. Article 1 was never ratified.3. Click on the Encrypt/Decrypt.4. SelectSymmetric (classic) from the drop down list.5. SelectVigenere….6. Enter a key ORANGE (you may want to try the encryption with other keys).7. Click Encrypt.8. Capture this screen (use PRTSCR key or SHIFT + PRTSCR on your keyboard) in Windows and paste the screenshot below.Activity 2Encryption with DES in CBC mode1. Repeat the first three steps of the process in Exercise 1 and select Symmetric (Modern).2. SelectDES (CBC)….3. In the pop-up window, select Encrypt (you may want to try the encryption with other keys).4. Capture this screen (use PRTSCR key or SHIFT + PRTSCR on your keyboard) in Windows and paste the screenshot below.Activity 3Asymmetric encryption using RSA Encryption1. Repeat the first three steps of the process in Exercise 1 above and select Asymmetric. 2. SelectRSA Encryption….3. Select SideChannelAttack (in the Last Name column).4. Click Encrypt.5. Capture this screen (use PRTSCR key or SHIFT + PRTSCR on your keyboard) in Windows and paste the screenshot below.6. Close CrypTool.Activity 41. On your computer, create a text file made up of at least five pages of text. The text can be anything you would like.2. Save the file on your C:\ drive as TEXT.txt3. Open CrypTool.4. Click on File.5. This time, select Open.6. Browse to C:\TEXT.txt7. Click on Encrypt/Decrypt.8. Select Asymmetric.9. Select RSA Encryption….10. Check the Display Encryption Time box at the bottom of the page.11. Select SideChannelAttack (in the Last Name column) in the window.12. Click Encrypt.13. A window with the “RSA encryption time:” message will pop up. Capture this screen (use PRTSCR key or SHIFT + PRTSCR on your keyboard) in Windows and paste the screenshot below.Notice that the RSA encryption time is relatively large for similar computing tasks. Symmetrical encryption, for instance, would take less than 0.001 seconds to encrypt the same text.
