SWEX-NG

Native macOS Summoners War profile exporter — Tauri 2 + React 19 + Rust.

A modern, native reimplementation of Summoner's War Exporter: it intercepts the game's gateway_c2.php call, decrypts it, and saves your profile JSON — but built for Apple Silicon, with the macOS set-up fully automated.

Why

The original SWEX is excellent, but on a modern Mac it shows its age:

• It's Electron + a precompiled x64 native addon for the decrypt key — no arm64 build existed, so it ran under Rosetta on Apple Silicon.
• It made you trust a certificate in Keychain and set the system proxy by hand.

SWEX-NG fixes all three:

• Native arm64 (and Intel). The decrypt is pure Rust (aes + cbc + flate2), so the binary is architecture-independent — no Rosetta.
• No Electron / Chromium. Tauri shell (system WebView + Rust core) — a few MB instead of ~150.
• Zero manual macOS setup. It trusts its own CA (user login keychain, silently, no admin) and sets/clears the system HTTPS proxy itself. No Keychain steps, no Proxyman.
• In-app auto-updates, signature-verified, from GitHub Releases.

How it maps to the original

SWEX (original)	SWEX-NG
http-mitm-proxy	hudsucker (Rust MITM)
node-forge CA generation	rcgen
native smon_decryptor addon	pure Rust aes + cbc + flate2 (src-tauri/src/decode.rs)
mapping.js (~2350 lines)	embedded mapping.json + ported helpers (mapping.rs)
Electron + React 16	Tauri 2 + React 19 + Vite 6
manual Keychain + Network proxy	security + networksetup, automated (macos.rs)

Install

1. Download the latest .dmg from Releases.
2. Drag SWEX-NG into Applications.
3. The app is not Apple-signed yet, so the first launch is gated by Gatekeeper. Either right-click the app → Open, or run once:

   xattr -dr com.apple.quarantine /Applications/SWEX-NG.app

   Every update after that installs in-app, with no warning.

The one thing you provide: your decryption key

The 16-byte AES key is not in this repo — it belongs to the game and lived inside the original's precompiled addon. Extract it once from your existing, working SWEX checkout:

./node_modules/.bin/electron -e "console.log(require('./app/proxy/binaries/key-darwin-x64.node').key().toString('hex'))"

That prints 32 hex characters. Paste them into SWEX-NG's Decryption key field (stored locally in the app's data dir, never committed, never sent anywhere), or set SWEX_KEY=<hex> in the environment.

Using it

1. Paste the key (first launch only).
2. (Optional) pick an Output folder — defaults to the app's data dir.
3. Set a port (default 8080) and click Start proxy. macOS is configured automatically — no password, no prompts.
4. Open Summoners War and wait for the login / "Press Any Button" screen.
5. Your profile is decrypted and saved as {wizard_name}-{wizard_id}.json; the UI shows monster/rune counts and a button to open the folder.
6. Click Stop proxy — or just quit; the system proxy is restored automatically either way.

Only *.qpyou.cn traffic is intercepted; everything else is tunnelled untouched (same surgical behaviour as the original — your other apps are unaffected).

World Guild Battle defense (a small extra)

Your WGB defense teams aren't part of the login payload — the game only sends them when you open the WGB defense screen. Open it once while the proxy is running and SWEX-NG merges those teams (with full rune/artifact builds) into the same profile file under a guildwar_defense key. The original Summoners War Exporter doesn't capture this — it's a small bonus on top of full profile parity, not a competition.

Build from source

Prerequisites: Rust (stable), Node 20 + pnpm, cmake (brew install cmake, needed by aws-lc-rs), Xcode Command Line Tools.

pnpm install
pnpm tauri dev      # development
pnpm tauri build    # native .app / .dmg

Tests: cargo test --manifest-path src-tauri/Cargo.toml.

Roadmap

• Linux / Windows — the proxy + decrypt core is cross-platform; what's missing is each OS's cert-trust + system-proxy module (the macOS one lives in macos.rs).
• Apple notarization for friction-free installs (needs an Apple Developer ID).
• Rune optimizer built on the bonus monster_name / rune_efficiency commands.

Security & privacy

Your key and your profiles never leave your machine. The proxy intercepts only *.qpyou.cn and tunnels everything else untouched. See SECURITY.md.
