Functionality

What does this app do?

A SHA256SUM hash key can be generated by running a 256-bit algorithm over an ISO image containing a linux distribution to cross check it's validity. While consuming a Debian distribution should only be done through an official developer portal to begin with, running a checksum will increase confidence that the image is legitimate. This program is designed to streamline this cross-checking process in order to deliver immediate feedback on the quality of your image.

Learning Goals

• Experience interacting with Python data types
• Increase visibility (yes, I am still working on things)
• Introduction to built-in RegEx functions in Python
• Practice understanding of IO procedure
• Utilize a Python debugger
• Build a tool that I can use for at home projects

Installation

How to use this tool

1. Clone the repo:

   git clone [e-mail]:4D-Coder/SHA256SUM_verifier.git


2. Once you have the tool locally, add your iso file to the root directory of the project.


3. Included with the cloned project is a 256SHASUMS.txt file containing hashes for the most recent Debian live images at the time of this project's creation.
   • Ensure that you have the most relevant and recent 256SHASUMS.txt for your image from the Debian official site!



4. Calculate your SHA-256 hash using your utility of choice so that you have your 256-bit code and iso name like so:

5. Open up your terminal, cd into the project root directory, and run run.py to start the program!
