In this project, you will create a file on a USB drive and calculate its hash value in FTK Imager Lite. Then you will change the file and calculate the hash value again to compare the files. You will need a Windows computer and a USB drive. 1. Create a folder called C4Prj04 on your USB drive, and then start Notepad. 2. In a new text file, type "This is a test of hash values." One definition of a forensic hash is that if the file changes, the hash value changes. 3. Save the file as "hash1.txt" in the C4Prj04 folder on your USB drive, and then exit Notepad. 4. Start FTK Imager Lite (clicking OK or Yes in the UAC message box, if necessary), and click "File" > "Add Evidence Item" from the menu. In the "Select Source" dialog box, click the "Logical Drive" option button, and then click "Next." 5. In the "Select Drive" dialog box, click the "Source Drive Selection" list arrow, click to select your USB drive, and then click "Finish." 6. In the upper-left pane, click to expand the USB drive and continue expanding until you can click the C4Prj04 folder. In the upper-right pane, you should see the "hash1.txt" file you created. 7. Right-click the file and click "Export File Hash List." Save the file as "original hash" in the C4Prj04 folder on your USB drive. FTK Imager Lite saves it as a .csv file. Exit FTK Imager Lite, and start Notepad. 8. Open "hash1.txt" in Notepad. Add one letter to the end of the file, save it, and exit Notepad. 9. Start FTK Imager Lite again. Repeat Steps 4 to 7 (but without starting Notepad), but this time when you export the file hash list, save the file as "changed hash." 10. Open the "original hash" and "changed hash" files on your USB drive in Excel or another spreadsheet program. Compare the hash values in both files to see whether they're different, and then exit Excel and FTK Imager Lite.

Find two different files on the Web with the same SHA1 hash value and the same file size. You just need to submit the URLs of those two files.
