Why Hackers Can’t Unhash Your Password

In this video, you’ll learn what hashing really is, how it differs from encryption, and why hash functions can never be reversed. Many beginners confuse hashing with encryption because both transform data into unreadable values. In this lesson, we break that confusion by first showing simple mathematical functions that do have reverse operations—where an output can be decrypted back to the original input. We then explain why those reversible functions are NOT hashing. You’ll discover: What hashing is in simple terms Why hash functions are one-way by design Why a hash can never have a “reverse function” How hashing is different from encryption and encoding Why passwords are hashed instead of encrypted How bcrypt works conceptually and why it’s used in real-world applications We also explain salting, uniqueness, and verification, showing how systems check passwords without ever knowing the original password. This video is perfect for: Beginners learning cybersecurity Students studying computer science or software engineering Developers using Node.js, Express, or authentication systems Anyone confused about “decrypting hashes” By the end of this video, you’ll clearly understand why hashing cannot be reversed, why that’s a security feature, and how modern systems like bcrypt protect user passwords. 🔍 Keywords / Topics Covered hashing explained why hashing cannot be reversed hashing vs encryption one way hash function bcrypt explained password hashing cybersecurity basics authentication and security how passwords are stored hash functions explained
