- WASM crypto bundle (175KB): 13 wasm_bindgen functions wrapping quicproquo-core's Ed25519 identity, X25519+ML-KEM-768 hybrid KEM, safety numbers, sealed sender, and message padding - @quicproquo/client TypeScript SDK: QpqClient class with connect, health, resolveUser, createChannel, send/sendWithTTL, receive, deleteAccount; WebSocket transport with request/response correlation and reconnection; ergonomic crypto.ts wrapper over WASM functions - Browser demo: vanilla HTML page with interactive crypto operations (identity gen, safety numbers, sign/verify, hybrid encrypt/decrypt, sealed sender, padding) and chat UI for server connectivity - Offline mode: crypto operations work without server connection TypeScript strict mode, 0 errors. WASM bundle size optimized (lto + opt-level=s).
@quicproquo/client
TypeScript SDK for quicproquo -- an E2E encrypted group messenger built on MLS (RFC 9420), hybrid post-quantum key exchange (X25519 + ML-KEM-768), and sealed sender envelopes.
Features
- WASM-powered crypto -- Ed25519 signatures, hybrid KEM, sealed sender,
message padding, safety numbers -- all compiled from the Rust
quicproquo-corecrate viawasm-pack. - High-level client API --
QpqClientwraps transport + crypto into a type-safe interface for resolving users, creating channels, and exchanging messages. - Offline mode -- All crypto operations work without a server connection.
Use
QpqClient.offline()for key generation, signing, encryption, etc. - Transport abstraction -- Pluggable
Transportinterface with a built-inWebSocketTransportfor browser environments.
Quick start
import { QpqClient } from "@quicproquo/client";
// Crypto-only (no server needed)
const client = await QpqClient.offline();
const alice = client.generateIdentity();
const bob = client.generateIdentity();
const safetyNumber = client.computeSafetyNumber(alice.publicKey, bob.publicKey);
console.log("Safety number:", safetyNumber);
// Sign and verify
const msg = new TextEncoder().encode("hello");
const sig = client.sign(alice.seed, msg);
console.log("Valid:", client.verify(alice.publicKey, msg, sig));
Server connection
The native qpq server speaks Cap'n Proto RPC over QUIC/TCP with Noise_XX. Browsers cannot open raw TCP sockets, so a WebSocket bridge proxy is required for full server connectivity:
const client = await QpqClient.connect({ addr: "wss://bridge.example.com" });
const peerKey = await client.resolveUser("bob");
const channel = await client.createChannel(peerKey);
