Easy File Encryption in C++ | Build Your Own Encryption Tool [FULL TUTORIAL]

In this comprehensive tutorial, you'll learn how to build a simple yet powerful File Encryption/Decryption Tool using C++. File encryption is a fundamental technique used to secure sensitive data and protect it from unauthorized access. Throughout this step-by-step video, we'll guide you through the process of creating your own encryption tool from scratch.

No prior knowledge of encryption or C++ is required; we'll start with the basics and gradually introduce more advanced concepts. You'll discover the fascinating world of cryptography and understand the workings of the famous Caesar cipher, one of the oldest and simplest encryption algorithms.

We'll walk you through every detail, from setting up your development environment to implementing the core encryption logic. By the end of this video, you'll have a fully functional File Encryption/Decryption Tool that can secure your data and provide peace of mind.

Whether you're a programming enthusiast, a cybersecurity student, or simply curious about encryption techniques, this tutorial is designed for you. Join us in this hands-on journey to master C++ programming and encryption fundamentals while creating your very own File Encryption/Decryption Tool.

Don't miss out on this exciting learning opportunity. Hit that play button, and let's dive into the world of cryptography together!

What do you recommend as the most basic/beginner way to do this? What would one learn/understand first? Thanks! =).

Can you make one that i can use in real life scenarios?

hello great code btw! I have tried the same code but i keep getting errors when i try to compile it, also for some reason I don’t get a command window when i run, excuse my English but what do you think the problem is? Thank you again ❤

Very good content man! But i did face an issue. When i ran it on cmd it gave this error :


encryption.cpp: In function 'bool encryptFile(const string&, bool)':
encryption.cpp:29:56: error: expected primary-expression before '{' token
string content((istreambuf_iterator<char>(inFile), {});
^
encryption.cpp:29:56: error: expected ')' before '{' token



im confused what do i do?

[raghadbburhan]

can this code work in another IDE like dev c++?
