Project 2-1: Use an Online Password Cracker

In this project, you will create a digest on a password and then crack it with an

online cracking website to demonstrate the speed of cracking passwords.

1. The first step is to use a hash algorithm to create a password digest. Use

your web browser to go to www.fileformat.info/tool/hash.htm (if you

are no longer able to access the site through the web address, use a search engine to

search for “Fileformat.Info hash functions”).

2. Under String hash, enter the simple password apple123 in the Text: line.

3. Click Hash.

4. Scroll down the page and copy the MD4 hash of this password to your Clipboard by

selecting the text, right-clicking, and choosing Copy.

5. Open a new tab on your web browser.

6. Go to https://crackstation.net/.

7. Paste the MD4 hash of apple123 into the text box beneath Enter up to 10 non-salted hashes:.

8. In the RECAPTCHA box, enter the current value being displayed in the box that says

Type the text.

9. Click Crack Hashes.

10. How long did it take this online rainbow table to crack this hash?

11. Click the browser tab to return to FileFormat.Info.

12. Under String hash, enter the longer password 12applesauce in the Text: line.

13. Click Hash.

14. Scroll down the page and copy the MD4 hash of this password to your Clipboard.

15. Click to browser tab to return to the CrackStation site.

17. In the RECAPTCHA box, enter the current value being displayed in the box that says

Type the text.

18. Click Crack Hashes.

19. How long did it take this online rainbow table crack this stronger password hash?

20. How long did it take to crack your password hash (DO NOT TELL ME YOUR PASSWORD!!)?

21. What does this tell you about the speed of cracking passwords? What does it tell you about how easy it is for attackers to crack weak passwords?

22. Close all windows

Case Project 2.2

Case Project 2-1: Testing Password Strength

How strong are your passwords? Various online tools can provide information

on password strength, but not all feedback is the same. First, assign the numbers 1 through 3 to three of the passwords you are currently using, and write

down the number (not the password) on a piece of paper. Then, enter those passwords into

these three online password testing services:

• The Password Meter (www.passwordmeter.com/)

Record next to each number the strength of that password as indicated by these three online

tools. Then use each online password tester to modify the password by adding more random

numbers or letters to increase its strength. How secure are your passwords? Would any of

these tools encourage someone to create a stronger password? Which provided the best information? Create a one-paragraph summary of your findings.
