SCCA
Secure Compact Chat Architecture
Privacy-first AI conversations with AES-256-GCM encryption at rest, single-row storage, and Merkle integrity verification.
AES-256-GCM
Authenticated encryption for every message, with unique per-conversation keys.
Single-Row Storage
Entire conversations in one database row. Minimal footprint, maximum efficiency.
Merkle Integrity
HMAC-based chain verification ensures tamper-evident conversation history.
Destructive Editing
Irreversible edits with cryptographic re-keying. No ghost data, no traces.
