Lab Document Framework

Best Use of MD5 or SHA-1: Outline a scenario where the MD5 or SHA-1 algorithms are put to good and proper use. Start by stating what the algorithm does and give a use case where either MD5 or SHA-1 has a best fit condition. It is generally about 5–10 sentences.

Ethical Hacking of MD5: Copy the following text into your lab document and fill in the blanks.

MD5 Hash 1: 4eefef62c45d66f55d89c515d8352c5c Input was: _____

MD5 Hash 2: 5f4dcc3b5aa765d61d8327deb882cf99 Input was: _____

MD5 Hash 3: d6a6bc0db10694a2d90e3a69648f3a03 Input was: _____

Worst Use of MD5 or SHA-1: Outline a scenario where the MD5 or SHA-1 algorithms are put to poor or improper use. Start by stating what improper assumptions were made and how it did (or could) lead to a security compromise. It is generally about 5–10 sentences.

Citations and Resources Used in This Report: Tell us where you received external guidance and ideas. If you have presented original ideas, then give yourself credit, and tell us why you believe it is correct.
