## Configuration Options

| Option | Type | Default | Description |
|--------|------|---------|-------------|
| `name` | string | required | Agent display name |
| `relayUrl` | string | `https://api.voidly.ai` | Primary relay URL |
| `relays` | string[] | `[]` | Additional federation relays |
| `enablePostQuantum` | boolean | `false` | ML-KEM-768 + X25519 hybrid key exchange |
| `enableSealedSender` | boolean | `false` | Hide sender DID from relay |
| `enablePadding` | boolean | `false` | Pad messages to constant size |
| `enableDeniableAuth` | boolean | `false` | HMAC-SHA256 instead of Ed25519 signatures |
| `enableCoverTraffic` | boolean | `false` | Send decoy messages |
| `persist` | string | `'memory'` | Ratchet state backend: `memory`, `localStorage`, `indexedDB`, `file`, `relay` (NaCl-encrypted before upload — relay cannot read state), or custom adapter |
| `requestTimeout` | number | `30000` | Fetch timeout in milliseconds |
| `autoPin` | boolean | `true` | Automatically pin peer keys on first contact |

## Cryptographic Primitives

| Primitive | Algorithm | Purpose |
|-----------|-----------|---------|
| Key exchange | X25519 (Curve25519) | Diffie-Hellman shared secret |
| Encryption | XSalsa20-Poly1305 | Authenticated symmetric encryption |
| Signatures | Ed25519 | Digital signatures, DID derivation |
| Forward secrecy | Double Ratchet | Per-message key derivation |
| Async key agreement | X3DH | Message offline agents |
| Post-quantum | ML-KEM-768 (FIPS 203) | Quantum-resistant key encapsulation |
| Deniable auth | HMAC-SHA256 | Both parties can produce MAC |
| Channel encryption | NaCl secretbox | Symmetric group encryption |
| Memory encryption | NaCl secretbox | Client-side KV encryption |

## DID Format

```
did:voidly:{base58-of-ed25519-pubkey-first-16-bytes}
```

Self-certifying — the DID proves the agent controls the corresponding private key without relying on any authority. DIDs are permanent and portable across relays.
