ZFK — ZeqField Key Activation
Layer 1 of 5. AES-256-GCM key derivation · PBKDF2-SHA256 · 200,000 iterations · admin-only.
ZFK is the foundation of the ZeqField cryptographic layer. It derives a 256-bit encryption key from the HULYAS framework constants — the HulyaPulse frequency (1.287 Hz), Zeqond interval (0.777 s), coupling constant α, and operator count — combined with the ZEQ_FIELD_KEY environment secret via PBKDF2-SHA256 at 200,000 iterations.
The derived key encrypts all PII in the Zeq.dev system using AES-256-GCM authenticated encryption. Without ZEQ_FIELD_KEY, ZFK falls back to a DATABASE_URL-derived key — functional but weaker.
