How to use/reverse engineer Hash map keys


I have never come across hash maps before so please be gentle!

I have a task whereby I have a hash map key (I think that’s what it is) and I want to reverse engineer it to get the data it was generated from.

enter image description here

Does anyone have any ideas about how to do this?

Can you do this in excel-vba or is it best to use Java? What functions should I use?

Do I need extra information in order to do what I want?

Any help will be much appreciated!


Solution

  • Those aren't hash keys, they're GUIDs, "Globally Unique IDentifiers". The bad news is that they are simply computer-generated unique strings - there was no "data they were generated from".

    (If they were hash keys, the bad news would be that you can't recover the data they were generated from either - information is destroyed when hash keys are generated.)
