Within your course repository, create a directory "hw4". Commit and push to your remote repository.

cd <path_to_repo>
mkdir hw4
touch hw4/app.py
touch hw4/screencast_url.txt
git add hw4
git commit -m "initial commit for hw4"
git push

In this homework, based on the lab exercises, you will create your own LangChain application to automate a task in code summarization and reverse engineering. Some ideas include

• Summarizing git pull requests
• Analyzing packages for malicious code (example | example)
• Automatic, accurate code summarization for generating comments and documentation of code (example)
• Code classifier to determine if code sends data off-machine, modifies the registry, creates files, launches a process, reads environment variables, etc.
• Automatic code deobfuscator
• Automatic decoding/decrypting of data
• Reverse engineer malware samples (example | example | example | example)
• Automate the application of COTS reverse engineering tools (radare2, ghidra)

Your development should be organized and incremental, with frequent commits into your git repository. Code should also be properly documented via Python docstrings. In addition, you must also ensure API keys do not show up in your source files, but rather are passed in via environment variables. Ensure your application code is pushed to your repository before class.

Screencast

Upon completing your application, via a narrated screencast of no longer than 5 minutes, you will perform a demonstration and source code walk-through of the application using the script below.

• Check out the application source code from your course repository.
• Demonstrate the application running showing both its capabilities as well as its limitations
• Perform a source code walk-through using your repository on Gitlab to explain how the application has been implemented.

Upload your completed screencast on MediaSpace. Ensure that it is published as "Unlisted". Then, update the file screencast_url.txt in the homework's directory to contain the URL that your unlisted screencast on MediaSpace is located. Push the changes that include the updated URL to your repository before class.

Rubric

We will be using your screencast and git repository to evaluate your homework.
