Quantum Secure Encryption Corp. (QSE) announced the launch of qREK, a new Software Development Kit (SDK) designed to integrate post-quantum-resilient encryption into applications and systems. Released December 9, 2025, qREK enables organizations to locally generate encryption keys backed by QSE’s secure quantum-grade entropy, eliminating risks associated with remotely transmitted keys. Built on a zero-trust architecture, the SDK ensures cryptographic keys remain within the client environment while leveraging QSE’s globally distributed quantum entropy infrastructure, marking a milestone in delivering practical tools for modernizing security posture and preparing for the vulnerabilities expected with the advent of quantum computing.
qREK SDK Features and Functionality
QSE has launched qREK, a new Software Development Kit (SDK) designed to integrate post-quantum-resilient encryption into applications and systems. A key feature is local key generation, meaning encryption keys are created directly on the client’s machine, backed by QSE’s quantum-grade entropy. This eliminates risks associated with cloud-generated or remotely transmitted keys, building on a zero-trust architecture where keys never leave the client environment, while still utilizing QSE’s globally distributed quantum entropy infrastructure.
qREK is compatible with existing cryptographic standards like AES, RSA, and NIST-recommended Post-Quantum Cryptography (PQC) algorithms, including Kyber and Dilithium. Organizations can upgrade their security infrastructure without needing to replace existing systems, requiring only minimal code integration. The SDK supports both online and offline use through a “cache-now, crypt-later” fallback, strengthening current defenses while preparing for future quantum-enabled attacks.
According to QSE, qREK delivers a way to generate truly secure, quantum-resilient encryption keys without external exposure. By combining local key generation with remotely sourced quantum entropy, the SDK eliminates weaknesses found in traditional randomness sources and cloud-based key systems. This allows organizations to maintain complete ownership of their cryptographic lifecycle while benefiting from next-generation entropy designed for the post-quantum world.
Locally Generated, Quantum-Resilient Encryption
QSE has launched qREK, a Software Development Kit (SDK) enabling locally generated, quantum-resilient encryption. This means encryption keys are created directly on a client’s machine, rather than being generated in the cloud or transmitted remotely, enhancing security. qREK utilizes QSE’s secure quantum-grade entropy, providing a foundation for developers and enterprises to upgrade cryptographic infrastructure without fully replacing existing systems – requiring only minimal code integration.
qREK’s key generation is backed by authentic quantum entropy fetched securely from QSE data centers, and keys never leave the client environment. This design eliminates exposure risks associated with traditional key generation methods. The SDK is compatible with AES, RSA, and NIST-recommended Post-Quantum Cryptography (PQC) algorithms like Kyber and Dilithium, ensuring broad applicability and future-proofing against evolving threats.
According to QSE, qREK allows organizations to maintain complete ownership of their cryptographic lifecycle while benefiting from next-generation entropy. The SDK is designed for both online and offline use through a “cache-now, crypt-later” fallback, offering flexibility. QSE positions qREK as a critical step for organizations preparing for the post-quantum era and the cryptographic vulnerabilities expected with advancing quantum computing.
qREK is an important advancement for our company and a critical step forward for organizations preparing for the post-quantum era. For years, enterprises have relied on legacy approaches to key generation that simply weren’t built for the realities of modern cybersecurity-let alone the threats emerging with quantum computing.
