In this episode of Dot One, we unravel the fascinating world of cryptography, the backbone of digital security. From ancient ciphers like the Caesar cipher to the groundbreaking Enigma machine of World War II, cryptography has long played a vital role in protecting sensitive information. Today, encryption is everywhere—from securing internet traffic with TLS to protecting private conversations with end-to-end encryption. We’ll break down how cryptographic techniques work, explore the differences between symmetric and asymmetric encryption, and examine their critical role in ensuring confidentiality, integrity, and authentication in the digital age.

But cryptography isn't just about the past—it’s shaping the future, too. We discuss how modern advancements, like blockchain, homomorphic encryption, and post-quantum cryptography, are paving the way for more secure digital interactions. With the looming threat of quantum computing breaking traditional encryption, researchers are racing to develop quantum-resistant algorithms. Join us as we explore these groundbreaking innovations and why cryptography remains one of the most crucial defenses in our increasingly interconnected world.
