La science du secret vs Reversing: Which Should You Read?
Two cybersecurity books on Foundations, compared honestly: who each is for, what each does best, and which to read first.
A lucid popular-science history of cryptography by Jacques Stern, one of France's most eminent cryptographers — from classical ciphers to public-key and the science of secrecy.
The book that taught a generation how software actually looks once you strip away the source. Still the clearest on-ramp to thinking in assembly, even with dated tools.

Key takeaways
- Popular cryptography history written by a top-tier cryptographer (Stern, ENS), so the science is impeccable.
- Traces the arc from classical ciphers to public-key — the conceptual leaps, not the code.
- A French equivalent of The Code Book with a researcher's eye; dated on modern primitives but timeless on fundamentals.
- Reverse engineering is a disciplined reading skill, not magic; the fundamentals of how compilers, stacks, and calling conventions work outlast any tool.
- The most durable part of the book is the bridge from high-level constructs to their assembly fingerprints, which you will recognize for the rest of your career.
- The Windows-internals, copy-protection, and anti-reversing material is a snapshot of 2005 and should be treated as historical context, not current practice.
