Ypqc
A High-Performance Post-Quantum Cryptography Solution Meeting Both Global and Korean Standards
Ypqc by Whykeykeysoft is an integrated PQC library supporting 3 NIST global standards and 4 Korean KpqC standards — 7 post-quantum cryptography algorithms in total. It delivers C, Java, and WebAssembly implementations simultaneously, and is the first in Korea to offer an interactive browser-based Playground.
Key Differentiators
Full-Stack Cross Platform
Deploy Anywhere, Instantly
Low-level optimized implementation for embedded & IoT environments
Pure Java — no native dependencies (first in Korea)
WebAssembly build for browser & web frontends
→ One SDK covers embedded to cloud
Global & Local Compliance
NIST + KpqC, Simultaneously
FIPS 203 (ML-KEM) · FIPS 204 (ML-DSA) · FIPS 205 (SLH-DSA)
NTRU+ · SMAUG-T · HAETAE · AIMer — all 4 Korean standards
→ Ready for Korean public sector & financial compliance
Optimization & Hardening
Maximum Performance, Minimum Overhead
Endian optimization & precise memory handling
Low-power devices: zero-latency crypto operations
Web-optimized for instant in-browser execution
→ Same codebase from IoT to enterprise
ACVP Validated & Open Playground
Verified Trust · Open Test Environment
Full NIST ACVP test vector pass — implementation correctness guaranteed
First interactive browser PQC Playground in Korea
→ Proving reliability and ease of adoption
