Encryption is the foundation of modern security - from HTTPS and SSH to databases and cloud systems.

In this video, I explain everything you need to know about encryption, step by step, using whiteboard explanations, real-world examples, and practical use cases so you clearly understand how encryption protects data and where it’s used.

We focus on how encryption actually works, why keys matter, and how encryption is different from encoding and hashing — a common source of confusion for many developers.

In this video, you’ll learn:
• What encryption actually is
• Why encryption is needed
• Symmetric vs asymmetric encryption (high level)
• How keys are used in encryption
• Real-world examples (HTTPS, SSH, data at rest)
• Common encryption use cases in backend systems
• Mistakes developers make when using encryption

This video is designed to give you a strong conceptual foundation, whether you’re learning backend security for the first time or revisiting core fundamentals.
