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.
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!
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.)
