You are at a University and one of the requirements of that, is to be able to find things out for yourself, independently, and without being spoon-fed.
I will give you a clue: look for an application called JTR as a starter.
Then look for "decryption tools" and see some of the others. There are loads of tutorials. Just start with one that you understand and realise that there is a learning curve here.
See if you can get your hands on a couple of obsolete machines as "targets" and set up your own small network for experimentation. At least then you have an environment where you control the parameters.
As I posted earlier, don't use tools like Cain & Abel on the internet until you really understand them. You should not be getting responses from external third party sites if you are just "sniffing yourself".............. you are actually drawing unwelcome attention to yourself.
