Books

Go beyond the basics of Tor and learn how to build private, resilient services on the dark web. From onion routing and v3 onion services to real-world threats and secure deployment, this book gives you the technical knowledge and practical skills to host privacy-critical services without exposing where they live.

Advanced Cryptography: Professional Implementation Handbook Bridging the Gap Between Mathematical Proofs and Physically Secure, High-Performance Silicon & Software In standard software engineering, we write code to satisfy functional requirements. In cryptographic engineering, functional correctness is merely the starting line.This handbook is written for developers and security architects who need to build systems that survive the messy, hostile reality of physical CPU pipelines, untrusted hypervisors, and the impending dawn of cryptographically relevant quantum computers.Moving far beyond textbook algebra, this guide approaches cryptography with adversarial pessimism — treating every line of code as a potential timing leak, a cache-line split, or an opportunity for a fault-injection exploit.

See what your network traffic is really revealing. This practical guide breaks down TLS fingerprinting, JA3/JA4 and HTTP client identification, then shows you how to put them to work with Python, Go and Rust. From protocol internals to production pipelines, learn how to identify clients at scale without losing sight of privacy or operational reality.

What if your software could compute on sensitive data without ever seeing it? Private Computing with Homomorphic Encryption takes you from the core ideas to working, production-minded systems. Learn the math, schemes, libraries and design patterns you need to build with HE, judge its tradeoffs and know when it is the right tool for the job.
