A deep dive into symmetric and asymmetric cryptography: how they work, why both exist, and when to use each for real security.

A beginner-friendly guide to understanding cryptographic keys, how they secure your data, and why losing them means irreversible loss.

Discover why true randomness is the foundation of modern cryptography and why predictable systems always fail.

Understand the key differences between encryption, hashing, and encoding with clear examples and real-world applications.

A straightforward guide to the core concepts of cryptography that matter, without the jargon or math.

Deep dive into authenticated encryption: AES-GCM and ChaCha20-Poly1305 mechanics.

Exploring threshold cryptography and Shamir's Secret Sharing: real applications vs common myths.

Explore zero-knowledge proofs like Bulletproofs and Halo2, with practical examples in privacy-preserving authentication.

From Git commits to Bitcoin blocks, from TLS certificates to password hashes, SHA is everywhere. Most developers use it daily without understanding why it works, what actually breaks, and why you’re probably using it wrong.

One algorithm. One quantum computer. Every RSA key, every ECC key, every Bitcoin wallet you ever created becomes readable or forgeable in minutes. This isn't sci-fi. This is math.

It's 2025. PGP is still the gold standard for a lot of people who should know better. Time referee an autopsy on a corpse that refuses to stay buried.
