ISARA Radiate

Quantum-safe Toolkit


The ISARA Radiate™ Quantum-safe Toolkit is a high-performance, lightweight, standards-based quantum-safe software development kit, built for developers who want to test and integrate next-generation post-quantum cryptography into their commercial products.

Developers choose ISARA Radiate because of the professional tools and documentation, timely product releases and updates, and thorough testing. All backed by our team of embedded security experts available to assist you with your questions and custom integration needs.

License our optimized, proprietary implementation of NIST PQC candidate algorithms with confidence knowing it is free from copyleft licensed code, reducing your risk of accidentally exposing your intellectual property to the public domain.

Key Benefits

Accelerate time to market

• Give your development team the freedom to focus on product innovation and leave the implementation of quantum-safe cryptography to us
• Test how quantum-safe cryptography fits into your products today and be ready to deploy commercially faster than your competitors once NIST draft standards are available


• Confidently begin testing and integrating using our curated list of only the most promising algorithms from the NIST Post-Quantum Cryptography (PQC) Standardization process and the Internet Engineering Task Force (IETF)


• Intuitive APIs allow you to quickly leverage the quantum-safe library, written in highly portable C99 for various platforms and architectures
• Exhaustively tested, thoroughly documented with sample code provided

Professional integration tools

• Support for Java using the ISARA Radiate JNI Wrapper to facilitate a seamless integration into solutions written in Java, saving you time and resources

HSS & XMSS: Production-ready for roots of trust and code-signing

• Stateful hash-based signatures, Hierarchical Signature Scheme (HSS) and eXtended Merkle Signature Scheme
(XMSS), are well trusted to be used today for specific use cases
• Undergoing NIST standardization (SP 800-208, expected to be completed soon.) IETF has completed specifications under IRTF RFC 8391 and IRTF RFC 8554
• Small public key and comparable performance to ECC-based signature schemes
• Includes ISARA’s proprietary approach to state management of the large, stateful private key

ISARA Radiate Cryptographic Library Version 2.0 includes the following quantum-safe algorithms:

Services & Support

  • Professional Services

    Our experienced team of embedded security experts can help you implement quantum-safe security into your products as a professional services project.

  • Developer Support

    We offer a variety of different support packages to suit your specific needs. Please get in touch with our team for more details or to discuss custom packages.

  • Product Updates

    We regularly update the toolkit to align with the NIST PQC Standardization Process and to provide improvements and optimizations. Receive the latest version backed by developer support with a commercial license agreement.


NIST has undertaken the process for setting quantum-safe algorithm standards with draft standards available by 2022 – 2024. Learn more about the process and timelines on NIST’s website. However, the time frame to plan, test and implement agile quantum-safe security measures is shrinking. Switching out cryptographic algorithms which are deeply embedded and pervasive throughout the software stack is not a quick or simple task.

Fortunately, you don’t need to wait for standards to begin testing. Integrate ISARA Radiate in conjunction with ISARA Catalyst™ Agile Technologies to test and develop solutions that maintain current security measures, while adding post-quantum algorithms that are backward compatible. The toolkit combined with crypto-agility gives you the tools you need to protect high-value, critical assets and confidential data before standards are set, while maintaining your product’s current certifications.
