cf169b2a9e
Adds tools/ verifier scripts that exercise upstream RNS / LXMF and confirm (or correct) the SPEC.md callouts: - §2.3 HEADER_1→HEADER_2 conversion: verified by stubbing Transport.transmit and seeding a multi-hop path_table entry. - §4.3 app_data 3-element variant: producer in LXMF 0.9.6 actually emits 2 elements only (supported_functionality at LXMRouter.py:999 is dead code); parser tolerates 1/2/3-element + raw UTF-8. - §7.1 path? always-precedes claim: actually conditional on not has_path() AND method==OPPORTUNISTIC. - §7.4 ratchet ring default 8: actually Destination.RATCHET_COUNT = 512 at RNS/Destination.py:85. Also fixes a documentation bug in §1.2: the rnstransport.path.request row of the well-known-hash table had the dest-hash prefix where the name_hash should be (correct name_hash is 7926bbe7dd7f9aba88b0). Seeds test-vectors/identities.json (Alice + Bob) with a regenerator (tools/regen_identities.py) and verifier (tools/verify_destination_hash.py) covering §1.1 and §1.2.

# Test vectors
|
|
|
|
Known-good byte sequences that any Reticulum-compatible implementation should be able to round-trip in both directions.
|
|
|
|
## Status
|
|
|
|
Partially populated against RNS 1.2.0:
|
|
|
|
- ✅ `identities.json` — Alice + Bob identity vectors (regenerator: `../tools/regen_identities.py`, verifier: `../tools/verify_destination_hash.py`).
|
|
- ⏳ `announces.json` — not yet populated.
|
|
- ⏳ `lxmf.json` — not yet populated.
|
|
- ⏳ `links.json` — not yet populated.
|
|
|
|
See [`../agent.md`](../agent.md) §5 and [`../todo.md`](../todo.md) for the remaining bootstrap task list.
|
|
|
|
## Format (proposed)
|
|
|
|
Each vector lives in a per-domain JSON file, e.g.:
|
|
|
|
- `identities.json` — Alice + Bob with `encPriv`, `sigPriv`, `ratchetPriv` (hex), plus the derived `publicKey`, `identityHash`, `destinationHash` for `lxmf.delivery`
|
|
- `announces.json` — full hex of a signed announce packet, plus the inputs that produced it (display_name, ratchetPub, etc.)
|
|
- `lxmf.json` — sender + recipient identity, plaintext, expected ciphertext bytes
|
|
- `links.json` — LINKREQUEST + LRPROOF + derived session keys
|
|
|
|
Each entry should include:
|
|
|
|
```json
|
|
{
|
|
"description": "Alice's lxmf.delivery announce with ratchet, display_name='AliceTest'",
|
|
"inputs": { ... },
|
|
"expected_bytes_hex": "...",
|
|
"rns_version_at_generation": "1.2.0",
|
|
"generator_script": "tools/regen_announces.py"
|
|
}
|
|
```
|
|
|
|
The `generator_script` is the file in `../tools/` that, when run against upstream RNS, regenerates `expected_bytes_hex`. Keeping the generator alongside the vector lets a future contributor verify the vector still matches a newer upstream RNS.
|
|
|
|
## What needs to round-trip
|
|
|
|
For the spec to claim "an implementation that passes all test vectors interoperates with upstream", the vectors must cover:
|
|
|
|
1. **Identity construction** — given the same private-key inputs, derive the same public key, identity hash, destination hash.
|
|
2. **Announce build + parse** — build a signed announce; verify the same bytes come back through upstream's parser; verify upstream-built announces parse correctly.
|
|
3. **Token encrypt + decrypt** — bidirectional, with both ratchet and long-term keys.
|
|
4. **Opportunistic LXMF** — full plaintext → ciphertext → plaintext round-trip, signature valid both ways.
|
|
5. **Link handshake** — LINKREQUEST built by client A, LRPROOF computed by upstream as B, both arrive at the same `link_id` and session keys.
|
|
6. **Link-delivered LXMF** — body packed by client, decrypted + parsed by upstream.
|
|
|
|
A separate vector set for FAILURE cases is also useful: malformed announces, expired ratchets, mismatched signatures. An implementation should reject those as a regression-prevention measure.
