TQ42 Cryptography by Terra Quantum is a comprehensive, low-level cryptography library designed to cover Encryption, Hashing, Electronic Signatures, and Key Management Systems. It is specifically crafted to help individual developers, businesses, and governmental entities prepare for the quantum era and enhance the security of their data, and expands upon the existing functionality offered in TQ42, the quantum-as-a-service ecosystem by Terra Quantum.
This open-source C++ library offers a unified API for both post-quantum (PQ) and quantum-resistant algorithms, as well as key generation and management functions. View the documentation.
The library will expand to include support for additional languages (e.g., Python, iOS, Android), additional post-quantum algorithms, and upgrade options, like the ability to purchase quantum keys generated from Terra Quantum's proprietary Single Photon Quantum Random Number Generator (QRNG), which is designed and implemented according to the latest NIST standard (SP 800-90B) and certified by METAS.
Details on the library contents can be found in the documentation. Library contents are subject to change.

While there are no known vulnerabilities in the quantum-safe algorithms within this library, caution is crucial. These algorithms have not undergone the same level of scrutiny as currently deployed ones. The NIST Post-Quantum Cryptography Standardization project's guidance should be followed diligently. As research progresses, algorithm security may rapidly change, including potential vulnerabilities to classical and quantum computers.
TQ42 Cryptography aligns its algorithm support with the NIST PQC standardization project. Applications and protocols should rely on outcomes from this effort for post-quantum cryptography deployment.
For those considering quantum-safe cryptography before the NIST PQC standardization project concludes, we strongly recommend using hybrid cryptography. This approach combines quantum-safe public-key algorithms with existing traditional cryptography.
Terra Quantum offers advanced quantum security products, including the Terra Quantum Secure Network (TQSN), a novel solution for organizations looking for full security via Quantum Key Distribution (QKD), a revolutionary technology that leverages the quantum mechanical properties of light and allows for the distribution of cryptographic keys with absolute security, making decryption impossible. Terra Quantum's patented Secure Network solution (TQSN) works well over long distances with high bit rates. It is the world's first scalable, zero-trust Secure Network for global communications.
