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
