LanguageProject Introduction
Summary
The OQS-Provider is an OpenSSL 3 provider that allows integration and use of post-quantum cryptography algorithms from the liboqs library within the OpenSSL framework. It enables applications using OpenSSL 3 to experiment with and deploy quantum-safe algorithms for key exchange and digital signatures.
Problem Solved
Existing public-key cryptography standards (RSA, ECC) are vulnerable to attacks by large-scale quantum computers. This project offers a path for developers and organizations to adopt quantum-resistant algorithms using the widely deployed OpenSSL library.
Core Features
Comprehensive Algorithm Support
Provides access to a wide range of NIST PQC competition candidate algorithms (KEMs and Signature Schemes) through the OpenSSL 3 provider interface.
OpenSSL 3 Provider API Compliance
Seamlessly integrates with applications designed to use the OpenSSL 3 provider architecture, requiring minimal code changes.
Hybrid Mode Capability
Supports hybrid cryptography, allowing the use of PQC algorithms alongside traditional ECC or RSA for layered security.

Use Cases
The OQS Provider for OpenSSL 3 can be utilized in various scenarios requiring quantum-resistant cryptography:
Securing Network Protocols (e.g., TLS)
Details
Configure TLS servers and clients to negotiate PQC or hybrid (PQC + traditional) key exchange methods to secure communication channels against future quantum attacks.
User Value
Provides a path to quantum-safe encrypted communication using standard protocols.
Quantum-Resistant Digital Signatures
Details
Generate and verify digital signatures using post-quantum algorithms for code signing, document signing, or identity verification where long-term authenticity is critical.
User Value
Ensures the integrity and authenticity of data remains verifiable even after the advent of quantum computers capable of breaking current signature schemes.
Migrating Existing Applications to PQC
Details
Migrate existing applications using OpenSSL's libcrypto for key generation, encryption, and decryption to use PQC algorithms provided by the OQS provider.
User Value
Enables developers to upgrade the cryptographic core of their applications without a complete rewrite, leveraging existing OpenSSL knowledge.
