About.

Quantum Nexum builds and operates infrastructure for the transition to post-quantum cryptography. The mission is to make the migration to NIST's post-quantum standards practical for the people who actually have to do it — security engineers, developers, IT operators, and the auditors checking their work.

What ships today

PKI     coming soon — being refactored (AIA, CRL, OCSP endpoints folded in)
ACME    coming soon — gated on PKI refactor
Forge   in development — hands-on PQ tools, sandboxes, utilities
Vault   in development — PQ reference library
Core    planned — security principles + incident wisdom

What it isn't

• Not a public CA. Once the PKI lands it will be a private trust anchor — not in any browser's default trust store.
• Not a replacement for Let's Encrypt or DigiCert on the public web.
• Not a research outfit. Everything on this site cites primary sources (NIST, IETF, NSA, vendor docs); nothing here is original cryptographic research.
• Not a consultancy. No paid services are offered through this site.

Principles

Integrity, Assurance, Authority, Continuity. Cryptographic assertions on this site need to be verifiable; if a claim contradicts current standards or your own measurements, that's a bug worth telling us about.

Standards baseline

The post-quantum baseline this site is built around: NIST 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 into NSS deployments through 2033.
