Solving the Advanced Tasks

In this video, we will be focusing on solving one of the advanced tasks. If you're facing challenges with this particular task, don't worry, as this guide will walk you through the process.

Introduction

To begin with, we need to create a file that contains the password for the "Crack Me" executable. This file will play a crucial role in solving the task at hand. Let's dive into the steps to successfully complete this advanced task.

Creating a File for the Password

The first step in solving this advanced task is to create a file that will hold the password for the "Crack Me" executable. This password file will be used later in the process. To create the file, navigate to the root directory and use the command mkd followed by the desired name for the file.

Understanding Arrays

Before we proceed further, let's have a brief understanding of arrays. Arrays are a collection of elements of the same data type, stored in contiguous memory locations. Each element in an array can be accessed using its index value. This concept will be important as we progress through the task.

Size of Pointers

Pointers are variables that store memory addresses. In this task, we need to determine the size of a pointer. Pointers typically occupy 4 bytes of memory. Understanding the size of pointers helps us better analyze and solve the given task efficiently.

Storing Address in Pointer to Pointer

In one of the quiz questions, we are asked about the value stored inside a pointer to pointer for an integer. The answer lies in the fact that a pointer to pointer stores the address of another pointer. By utilizing this knowledge, we can successfully solve the task at hand.

Last Stand: Solving the Crack Me Executable

Now let's dive into solving the task titled "Crack Me." In this section, we will go through the step-by-step process of completing this task successfully.

Navigating to the Required Repo

To begin, navigate to the required repository where the "Crack Me" executable is located. This can be done by using the CD command followed by the path of the repository. Ensure you are in the root directory before proceeding.

Creating a Directory

If you haven't already created a directory for this task, use the mkd command followed by the desired directory name to create one. This directory will serve as a workspace for all the necessary files.

Navigating into the Directory

Once you have created the directory, navigate into it using the CD command followed by the directory name. This ensures that you are in the correct working directory for this task.

Creating the Password File

In order to solve the "Crack Me" task, we need to create a file that contains the password. Use the VI editor to create and edit the file. Paste the provided password into the file, save, and exit the editor.

Making the File Executable

After creating the password file, we need to make it executable. Use the chmod command followed by U+X and the file name to provide execution permissions to the file.

Checking the Code

Once you have completed the steps mentioned above, it's essential to check if your code is correct. Use the git add command, followed by the necessary files, to add your changes. Commit your changes with a suitable message and push them to the repository.

Conclusion

Congratulations! You have successfully solved the advanced task of cracking the executable. By following the steps outlined in this guide, you were able to create the password file, make it executable, and check your code.
