Hi, I'm Kyeson Blake Utley, here's what I'm building

I'm the founder of GhostKey Development, a small security engineering firm in Texas. We do post-quantum cryptography migrations, crypto and custody engineering, and penetration testing done entirely in-house.

Before this I ran SpookyGood, a blockchain forensics firm, tracing stolen crypto for fraud victims. The lesson that stuck: the cryptography almost never failed. The key handling did.

That's why I think post-quantum matters for AI founders specifically. Your API keys, customer data and model traffic are crossing the wire today, and "harvest now, decrypt later" means recorded traffic can be decrypted once a large quantum computer exists. NIST published the replacement standards in 2024 and plans to start retiring RSA and elliptic curves after 2030.

So I built Quantum Defense, a free 18-lesson course that takes you from no math to the internals of ML-KEM, with interactive demos in every lesson. No sign-up: quantumdefenseservices.com

Happy to help anyone thinking about agent key custody, secrets handling or a PQC roadmap. Ask me anything.
