Hi guys, thanks for the posts. I'm currently back to work on my assignment. Anyway, all of the code that is from me is written by me. My lecturer only provided a module (is it called a module?) named ST2614, which helps encode and decode my hashes. Will update if I have more questions.

Thanks a million!

UPDATE: Okay, I managed to figure out what I want to ask. The problem is this: I have to decode the encrypted file of hashes, when I manage to decode it, I declare the result to a variable. Is this correct?

Second, I want to first print only all hashes that match the argument "site name" where a user might enter 'a' and some example results are hashes with key names such as Yahoo or Facebook printed. How can I do this?

Lastly, I would like to print all hashes that are decoded. However as I declared the decoded data into a variable, I don't think I can code the program like a typical print-all-hashes that Dave provided.. There seems like something I'm supposed to do, but honestly.. I'm clueless. So I'd like to ask how I could do this as well.

For the last blank, D, it's meant to be able to delete hashes which key exactly matches the one stated by the user. I haven't started work on it, hence I left it blank.

Once again thank you guys for the help. It's the holidays in my country over here, and I have trouble contacting my lecturer. This is why I cannot contact him for questions.
