ISARA Radiate Quantum-safe Toolkit by ISARA Corporation is a high-performance, lightweight, standards-based quantum-safe software development kit designed for developers to test and integrate post-quantum cryptography into their products. It provides optimized implementations of NIST Post-Quantum Cryptography (PQC) candidate algorithms, free from copyleft licensed code, reducing the risk of exposing intellectual property. The toolkit includes cryptographic building blocks to create applications that resist attacks by quantum computers, offering various algorithms for key establishment, digital signatures, key encapsulation mechanisms, and other cryptographic primitives.
