Encryption Algorithm

An Encryption Algorithm is a mathematical procedure used to transform readable data (plaintext) into an unreadable format (ciphertext), ensuring that only authorized parties can access the original information. In essence, it’s the heart of data security — protecting everything from your WhatsApp messages to online banking transactions.

In this video, we break down how encryption algorithms work, the difference between symmetric and asymmetric encryption, and popular algorithms like AES (Advanced Encryption Standard), RSA, and SHA-256 used in blockchain technology. You’ll learn how keys are generated, exchanged, and managed to maintain confidentiality and integrity in digital communication.

We’ll also explore real-world applications: securing email, encrypting cloud data, and protecting cryptocurrency wallets. Whether you’re a beginner curious about cybersecurity or a developer aiming to implement encryption in your apps, this video will give you a clear, practical understanding of how encryption keeps the digital world safe.

By the end, you’ll not only understand what encryption algorithms are, but also why they matter in every click, transaction, and connection online.
