Awesome PQC (Post Quantum Cryptography) Resources

A curated collection of cutting-edge resources on PQC (post quantum cryptography).

Introduction

Quantum computers will one day be powerful enough to break today’s widely used cryptographic systems, such as RSA and ECC. To prepare for this shift, post-quantum cryptography (PQC) is being developed to ensure our digital world remains secure in the quantum era.

This repository brings together:

• Standards & drafts from NIST, IETF, and other bodies.
• Handbooks, guides, and migration strategies for organizations.
• Implementations, tools, and software to experiment with PQC today.
• Research papers, publications, and events driving the field forward.

Whether you’re a developer, researcher, or security architect, this list will help you stay up-to-date and navigate the transition toward quantum-resistant cryptographic systems.
