Applied Post Quantum Cryptography Using Java 27

Cryptographic migration takes years, while sensitive information may need protection for decades. Applied Post Quantum Cryptography Using Java 27 gives Java developers a practical guide to the quantum threat and the standards designed to address it.

Explore ML-KEM key establishment, ML-DSA and SLH-DSA signatures, identity and certificate trust, hybrid key establishment, and TLS 1.3 integration. The examples use Java 27 JCA, JCE, and JSSE, with Bouncy Castle where needed. Symmetric encryption, hashing, and classical cryptography appear only to explain how PQC fits into deployed systems.

The book also covers PQC standards and algorithm status, provider and protocol support, certificate interoperability, harvest-now-decrypt-later risks, active attacks, and staged migration. Each example explains its assumptions and limits: a KEM does not authenticate a peer, algorithm availability does not establish module validation, and hybrid protocols must use defined combinations.

Written for developers comfortable reading Java, this book helps teams inventory quantum-vulnerable systems and prepare a safe, testable transition to post-quantum cryptography.
