• Abstract: The rapid advancement of quantum computing poses a significant threat to modern cryptographic systems, necessitating the transition to Post-Quantum Cryptography (PQC). This study evaluates the support for PQC algorithms within nine widely used open-source cryptographic libraries -- OpenSSL, wolfSSL, BoringSSL, LibreSSL, Bouncy Castle, libsodium, Crypto++, Botan, and MbedTLS -- focusing on their implementation of the NIST-selected PQC finalists: CRYSTALS-Kyber, CRYSTALS-Dilithium, FALCON, and SPHINCS+. Our analysis, based on the latest available documentation, release notes, and industry reports as of early 2025, reveals a varied state of readiness across these libraries. While some libraries have integrated PQC support or have clear implementation roadmaps, others lag behind, creating potential security risks as quantum threats become more imminent. We discuss key challenges, including performance trade-offs, implementation security, and adoption hurdles in real-world cryptographic applications. Our findings highlight the urgent need for continued research, standardization efforts, and coordinated adoption strategies to ensure a secure transition to the quantum-resistant cryptographic landscape.
