PQC Business
Proactively providing post-quantum cryptography solutions against quantum computer threats.
What is Post-Quantum Cryptography (PQC)?
Quantum computers are one of the most globally focused fields alongside AI. Commercialization timelines continue to be moved up, with some researchers claiming they are imminent.
Quantum computing can dramatically shorten computation for specific tasks, threatening to break RSA and ECC — the most widely used public-key cryptography today — in a very short time.
Algorithms developed to counter this quantum threat are called Post-Quantum Cryptography (PQC). NIST recommends that major organizations adopt PQC by 2028.

Ypqc SDK Development
WhyKeyKeySoft WhyKeyKeySoft has developed Ypqc, a post-quantum cryptography SDK, based on a team of cryptography experts.
The Ypqc SDK is implemented in both C and Java to support diverse operating environments, and both SDKs have been validated using NIST's published test vectors.
Optimized and lightweighted per algorithm for IoT and embedded environments, delivering excellent performance even on low-spec devices.
Implemented in Pure Java for web environment compatibility and scalability.
