Quantum Nexum

Post-quantum trust infrastructure.

Tools, references, and a post-quantum public key infrastructure for the transition to post-quantum cryptography. PKI is being refactored; Forge and Vault are in development.

If anything on this site contradicts current standards or your own measurements, please tell us — that's a bug, not a feature.

Standards we're tracking

The post-quantum baseline is NIST's three finalized standards: FIPS 203 (ML-KEM, key encapsulation), FIPS 204 (ML-DSA, signatures), and FIPS 205 (SLH-DSA, stateless hash signatures), all published August 13, 2024. NSA's CNSA 2.0 timeline phases these in across categories; exclusive use is required across all categories by 2033.
