# Python SDK
|
|
|
|
The Python SDK provides both async QUIC transport and synchronous Rust FFI backends.
|
|
|
|
Location: `sdks/python/`
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
pip install quicprochat
|
|
```
|
|
|
|
## Transport Backends
|
|
|
|
### Async QUIC (pure Python)
|
|
|
|
Uses [aioquic](https://github.com/aiortc/aioquic) for native QUIC transport with the v2 protobuf wire format. No Rust build required.
|
|
|
|
```python
|
|
import asyncio
|
|
from quicprochat import QpqClient, ConnectOptions
|
|
|
|
async def main():
|
|
client = await QpqClient.connect(ConnectOptions(
|
|
addr="127.0.0.1:5001",
|
|
ca_cert_path="ca.pem",
|
|
))
|
|
|
|
health = await client.health()
|
|
print(f"Server: {health.status}")
|
|
|
|
# OPAQUE auth (requires external OPAQUE library)
|
|
resp = await client.login_start("alice", opaque_request)
|
|
token = await client.login_finish("alice", finalization, identity_key)
|
|
|
|
# Messaging
|
|
key, proof = await client.resolve_user("bob")
|
|
seq, proof = await client.send(key, b"hello")
|
|
messages = await client.receive_wait(my_key, timeout_ms=5000)
|
|
|
|
await client.close()
|
|
|
|
asyncio.run(main())
|
|
```
|
|
|
|
### Rust FFI (synchronous)
|
|
|
|
Wraps `libquicprochat_ffi` via CFFI for full Rust crypto stack at native speed.
|
|
|
|
```sh
|
|
cargo build --release -p quicprochat-ffi
|
|
```
|
|
|
|
```python
|
|
from quicprochat import QpqClient, ConnectOptions
|
|
|
|
client = QpqClient.connect_ffi(ConnectOptions(
|
|
addr="127.0.0.1:5001",
|
|
ca_cert_path="ca.pem",
|
|
))
|
|
|
|
client.ffi_login("alice", "password123")
|
|
client.ffi_send("bob", b"hello")
|
|
messages = client.ffi_receive(timeout_ms=5000)
|
|
client.close_sync()
|
|
```
|
|
|
|
