Chris Murphy, a Superior Bicycles employee suspected of industrial espionage, had a Windows XP system formatted in NTFS that was seized as part of the investigation. Leave Hex Workshop running for the next project.Īctivity 2: In this project, you validate the files used in Hands-On Projects 9-3 and 9-4. Write a short paper stating whether you think this method is a reliable one for encrypting. Attempt to undo the procedure by working in reverse, as in Step 9.ġ3. Save theįile as correspondence2.txt in your work folder. Open the file again in Hex Workshop, and repeat Steps 7 and 8. Therefore, the original data is lost or modified. The bits that fall off one end of the number when it’s rotated are discarded In a normal (nonrotated) shift operation, Shift Right, click Shift Left twice, and click OK as needed.ġ0. Attempt to reverse the procedure by doing the following: Click Block
Finally, click the Block Shift Left button.ĩ. Click the Shift Right button and click OK twice, noting how the data is being treated. In this way, no bits are lost, and the process can be reversed to restore the original message.ħ. In a rotated shift operation, the bits that “fall off” one end of the number as it’s rotated appear on the other end of the number. The file should return to its original form. In the Rotate Left Operation dialog box, make sure the same setting is listed in the Treat Data As text box as for the Rotate Right operation, and then click OK. Write down which one it is (assuming little endian is the byte ordering), and then click OK. As shown in the Operand section of the Rotate Right Operation dialog box, the data can be treated as an 8-, 16-, 32-, or 64-bit unsigned long. Start Hex Workshop, and open the correspondence.txt file.Save the file as correspondence.txt in your work folder, and then exit Notepad.We do not want the competition to be able to read it if they intercept the message. Start Notepad and type the following in a new text document: This document contains very sensitive information.Activity 1: In this project, you perform bit-shifting on a file and verify that the file can be restored.
