Cryptography

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.

Bridging Mathematical Proofs and Secure, High-Performance Software and HardwareIn cryptographic engineering, functional correctness is only the beginning. A secure algorithm can still fail when its implementation leaks timing information, mishandles memory, relies on weak randomness, or operates within an inadequately protected execution environment.Advanced Cryptography: Professional Implementation Handbook is an 86-chapter technical reference for developers, security engineers, and system architects who need to understand cryptography beyond mathematical definitions and textbook examples. It examines the relationship between cryptographic design, software implementation, processor behavior, hardware security, and formal verification.

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.
