I am new to reversing but have worked through a couple of them at this point. Very cool stuff and I have learned a lot. However, I am now facing impossible password which is a very different format. I have figured out step 1. Step 2 is what I am working on and I am not sure of the approach. Any suggestions? I have a vague idea of what is going on as it runs, but not how to solve. I am thinking maybe something like angr but is there a more straightforward way?
