The Unbreakable Code: Understanding the One Time Pad's Perfection and Practical Limitations

The One Time Pad is the only encryption method that is mathematically unbreakable. But if it's perfect, why don’t we use it everywhere? In this video, we’ll explore how OTP works, why it’s so secure, and the big problem that makes it impractical for everyday use. 0:00 Introduction 1:46 Basics of cryptography 2:39 Example: Caesar Cypher 4:14 Problems with Caesar Cypher 7:00 One-Time Pad 9:55 Why is One-Time Pad unbreakable 11:43 Why it's not used that much 13:04 Conclusion
