ISARA Radiate is a software development toolkit (SDK) for integrating post-quantum cryptography (PQC) into applications and devices. It provides developer-friendly libraries and APIs for deploying NIST-standardized PQC algorithms, including ML-KEM and ML-DSA, across a range of environments—from resource-constrained embedded and IoT devices to large-scale enterprise and cloud applications. The toolkit is available in two variants: - **Embedded Radiate**: Optimized for constrained devices such as IoT hardware and smartcards. - **Standard Radiate**: Designed for general-purpose devices and enterprise software. The product supports a three-step integration workflow—Integrate, Verify, and Migrate—intended to guide teams through deploying PQC algorithms, validating performance and compatibility, and executing a full cryptographic migration. Key technical properties include NIST PQC Security Level 5 compliance, MISRA-C compliant code for portability and reliability, and support for hybrid certificates that enable interoperability between legacy and upgraded cryptographic systems. The toolkit promotes crypto agility through an API that allows algorithm switching as standards evolve, and supports transition of internal PKIs from hybrid to fully quantum-safe states. Target industries include financial services (DORA, GDPR, PCI DSS compliance), government and public sector (CNSA 2.0, CISA alignment), and energy/utilities (OT networks, industrial control systems). Developer resources include a Developer's Guide, API Reference, README documentation, and GitHub sample code.
