First public release.
- python-can plugin interface
helixfor Helix CAN backends (can.Bus(interface='helix', ...)) over WebSocket - Encrypted communication: ECDH P-256 key exchange, AES-256-GCM (HTTP) and ChaCha20-Poly1305 (WebSocket)
- ChaCha20-Poly1305 decryption of streamed HTTP responses
(
CryptoSession.decrypt_http_chacha, responses markedX-Cipher: chacha20) HelixSession: pre-authenticated sessions that keep credentials out of the python-can bus configuration (and its DEBUG logs)- Device fingerprint pinning (
device_fingerprint=), trust-on-first-use by default; fingerprint computed locally from the device public key - Session-token authentication with single-use WebSocket tickets
- CAN FD support with correct DLC mapping
- Shared WebSocket connection across multiple buses to the same device
- REST API client: bitrate/timing configuration, bus on/off, channel state
- Robust reconnect behavior after failed initial connections
- Rate-limited receive-overflow warnings
- Opt-in device-side CAN frame batching (
can.Bus(..., batch=True)) for high-rate buses: one decrypt per batch instead of per frame
