Homework task - reversing the hash value

You can think of the pseudonyms as usernames. Then the hashes could correspond to the unsalted hashed passwords that have leaked due to a breach. Choose the pseudonym that is assigned to you and answer the following questions.

  1. What was the input that was hashed?
  2. Which hash function was used?

The solution must be written to a text file (with .txt extension, not in a .docx file!!!) that contains only two rows. The first row must only contain the found input value. The second row must only contain the name of the hash function. In case you add any additional information or do not use the required file type or file format then the automatic grading script can give you 0 points. In case you are using Windows then you can create a text file with the software Notepad.

If you think that you know how the task should be solved, but can not find the input, try the same approach with other students' hashes. If the approach works for them, but not for your hash, maybe there is something wrong with the hash value -> send an email to the lecturer.


The solution has to be submitted to the submission form of the hash breaking task: submission form.
