Parallel File Encryptor using Multithreading in C++

Prerequisite to run the project

Create a .env file having your encryption_key in the project root directory.

How to run the project?

To run the whole project run these commands in your terminal:

1. make clean to clean the project.
2. make to build the project.
3. Run ./encrypt_decrypt to encrypt and decrypt the file.
   • It will ask the directory of the files to encrypt/decrypt.
   • It will then ask task to perform (ENCRYPT/DECRYPT).

To run the standalone cryption program run these commands in your terminal:

1. make clean to clean the project.
2. make cryption to build the project.
3. Run ./cryption your_task_data_here to encrypt/decrypt the data.
   • It will ask the task to perform (ENCRYPT/DECRYPT).

Prerequisite to debug in VS Code

Add following files inside the .vscode folder:

1. launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug encrypt_decrypt",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/encrypt_decrypt",
            "args": [],
            "cwd": "${workspaceFolder}",
            "preLaunchTask": "build"
        },
        {
            "name": "Debug cryption (standalone)",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/cryption",
            "args": ["your_task_data_here"],
            "cwd": "${workspaceFolder}",
            "preLaunchTask": "build"
        }
    ]
}

For linux use "type": "cppdbg", for mac use "type": "lldb", and for windows use "type": "gdb".

2. task.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "shell",
            "label": "build",
            "command": "make",
            "args": [],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
