Receiving a python script that encrypts a string using a user-chosen key, and an encrypted message- try to get the flag.
I really want to try this one and solve it. Started in a competition but didn't know where to go.
Can you decode this ciphertext? 809fdd88dafa96e3ee60c8f179f2d88990ef4fe3e252ccf462deae51872673dcd34cc9f55380cb86951b8be3d8429839
Using the hex above and python file to get a solution.

SCV is too hungry to mine the minerals. Can you give him some food?

I am just going to guess because it deals with food, it will be a buffer overflow.

Can I take your order?

Write solution here
Going to start with a hint that it is a heap-based challenge.
This problem is an exe file which means it is a window executable file. What a joy.

I am going to guess it is going to need coding to complete a game or cheat the game. That or shell coding, not too sure at first glance. I only say that because of the point value at 500.
100 pts. If only I knew how to reverse engineer. I am guessing from tables it is referring to mapping.
Not too sure how to Interpret this, the lab member who wrote this "forgot" to write any documentation. This shit, and him, is bananas. B, A-N-A-N-A-S.
Write a solution if I ever attempt it
Write solution here if possible without nc into it.
Hey, I'm Grump!

The prophecy is more important than either of us! Reveal its secrets, Zeratul! The future rests on it!" -Karass-
I don't know what to think about the problem.
Realism. The Fact of reality.
