As the threat of quantum computing looms, post-quantum cryptography (PQC) is becoming essential for securing data. liboqs-java provides a Java wrapper for the C-based liboqs library, allowing Java developers to use PQC algorithms. However, building it on Windows x64 is non-trivial due to native dependencies. This tutorial walks through the entire process, from setting up a C compiler to linking the Java Native Interface (JNI). It covers common pitfalls like path configuration and library linking. For developers working on security-critical Java applications, this guide is a practical resource for future-proofing against quantum attacks. The signal here is the increasing demand for PQC integration in mainstream development environments, and the need for clear, platform-specific documentation.
