Leave Hex Workshop running for the next project. 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. If you’re prompted to create a backup, click Yes. Save the file as correspondence2.txt in your work folder. Open the file again in Hex Workshop, and repeat Steps 7 and 8. In a normal (nonrotated) shift operation, the bits that fall off one end of the number when it’s rotated are discarded therefore, the original data is lost or modified. Attempt to reverse the procedure by doing the following: Click Block Shift Right, click Shift Left twice, and click OK as needed. Finally, click the Block Shift Left button. 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. 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.Click the Rotate Left button. 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. We do not want the competition to be able to read it if they intercept the message.Save the file as correspondence.txt in your work folder, and then exit Notepad.Start Hex Workshop, and open the correspondence.txt file.Click the Rotate Right button. Start Notepad and type the following in a new text document: This document contains very sensitive information.

Download the necessary image file from the following link: Activity 1: In this project, you perform bit-shifting on a file and verify that the file can be restored.
PRODISCOVER BASIC CHECKSUM SOFTWARE
You will find these software under “Software for Labs” folder in Moodle. Description of the laboratory exercise: In this lab, you will use Sleuth Kit and Autopsy. Submission on Moodle is mandatory as an evidence of participation. Total Marks = 10 marks for 10 weeks (DIT and BNet) = 5 marks for 10 weeks (GDNet and MNet) Marks will be given only to students who attend and participate during 2 hours laboratory class.
BN309 Computer Forensics Laboratory 10 and 11: Digital Forensics Analysis and Validation Submission Due: End of laboratory class, submit the file on Moodle at least 10 minutes before the end of laboratory class.
