What You Need to Know

Geometric Key Space

Standard brute force will not work. The passphrase selects curvature parameters and geodesic flows on the underlying Riemannian manifold - the key space is geometrically structured, not enumerable by exhaustive search.

KDF Architecture

The "Riemannian Quay" KDF reduces geometric parameters to a deterministic 256-bit key via a SHA3-512-based expansion cascade. Understanding the manifold parameterization is prerequisite to recovering key material.

Authenticated Encryption

AES-256-GCM provides both confidentiality and integrity. Any tampering with encryptednews.bin will cause authentication failure. The AAD PHYLAX-BLACK-SWAN-NEWS must be supplied correctly during decryption.
