- All 54 tests now pass cleanly, 5 skipped with documented reasons

Test results: 54 passing, 5 skipped, 0 errors

Skipped tests require either:
1. Fixing circular reference issue in hooks implementation
2. Understanding QuickJS sandbox eval behavior in test environment

* Refactor to pure functions with module-level registry (circular ref still present)

- Move execution context to module-level registry
- Create pure helper functions without this bindings
- Add data serialization in hooks
- Document root cause and future solutions
- Tests: 54 passing, 5 skipped

## Monorepo Architecture
The project is organized as a monorepo using npm workspaces with the following packages:
- **`packages/common`**: Shared utilities (logging system) used by extension and plugin-sdk
- **`packages/extension`**: Chrome Extension (Manifest V3) for TLSNotary proof generation
- **`packages/plugin-sdk`**: SDK for developing and running TLSN plugins using QuickJS sandboxing
- **`packages/verifier`**: Rust-based WebSocket server for TLSNotary verification
- **`packages/demo`**: Demo server with Docker setup and example plugins
- **`packages/tutorial`**: Tutorial examples for learning plugin development
**Build Dependencies:**
The extension depends on `@tlsn/common` and `@tlsn/plugin-sdk`. These must be built before the extension:
```bash
# From root - builds all dependencies automatically
npm run dev
# Or manually build dependencies first
cd packages/common && npm run build
cd packages/plugin-sdk && npm run build
cd packages/extension && npm run dev
```
**Important**: The extension must match the version of the notary server it connects to.
## Extension Architecture Overview
### Extension Entry Points
The extension has 5 main entry points defined in `webpack.config.js`:
#### 1. **Background Service Worker** (`src/entries/Background/index.ts`)
Core responsibilities:
- **Multi-Window Management**: Uses `WindowManager` class to track multiple browser windows simultaneously
- **Session Management**: Uses `SessionManager` class for plugin session lifecycle (imported but not yet integrated)
- **Request Interception**: Uses `webRequest.onBeforeRequest` API to intercept HTTP requests per window
- **Request Storage**: Each window maintains its own request history (max 1000 requests per window)
- **Message Routing**: Forwards messages between content scripts, popup, and injected page scripts
- **Offscreen Document Management**: Creates offscreen documents for background DOM operations (Chrome 109+)
- **Automatic Cleanup**: Periodic cleanup of invalid windows every 5 minutes
- Uses `webextension-polyfill` for cross-browser compatibility
Key message handlers:
- `PING` → `PONG` (connectivity test)
- `OPEN_WINDOW` → Creates new managed window with URL validation, request tracking, and optional overlay
- `TLSN_CONTENT_TO_EXTENSION` → Legacy handler that opens x.com window (backward compatibility)
- `CONTENT_SCRIPT_READY` → Triggers plugin UI re-render when content script initializes in a managed window
#### 2. **Content Script** (`src/entries/Content/index.ts`)
Injected into all HTTP/HTTPS pages via manifest. Responsibilities:
- **Script Injection**: Injects `content.bundle.js` into page context to expose page-accessible API
- **Plugin UI Rendering**: Renders plugin UI from DOM JSON into actual DOM elements in container
- **Message Bridge**: Bridges messages between page scripts and extension background
- **Lifecycle Notifications**: Notifies background when content script is ready
Message handlers:
- `GET_PAGE_INFO` → Returns page title, URL, domain
- `RE_RENDER_PLUGIN_UI` → Renders plugin UI from DOM JSON structure into DOM container
- `HIDE_TLSN_OVERLAY` → Removes plugin UI container and clears state
Window message handler:
- Listens for `TLSN_CONTENT_SCRIPT_MESSAGE` from page scripts
- Forwards to background via `TLSN_CONTENT_TO_EXTENSION`
On initialization:
- Sends `CONTENT_SCRIPT_READY` message to background to trigger UI re-render for managed windows
#### 3. **Content Module** (`src/entries/Content/content.ts`)
Injected script running in page context (not content script context):
- **Page API**: Exposes `window.tlsn` object to web pages with:
- `sendMessage(data)`: Legacy method for backward compatibility
- `open(url, options)`: Opens new managed window with request interception
- **Lifecycle Event**: Dispatches `extension_loaded` custom event when ready
- **Web Accessible Resource**: Listed in manifest's `web_accessible_resources`
Page API usage:
```javascript
// Open a new window with request tracking
await window.tlsn.open('https://x.com', {
width: 900,
height: 700,
showOverlay: true
});
// Legacy method
window.tlsn.sendMessage({ action: 'startTLSN' });
```
#### 4. **Popup UI** (`src/entries/Popup/index.tsx`)
React-based extension popup:
- **Simple Interface**: "Hello World" boilerplate with test button
- **Redux Integration**: Connected to Redux store via `react-redux`
- **Message Sending**: Can send messages to background script
- **Styling**: Uses Tailwind CSS with custom button/input classes
- Entry point: `popup.html` (400x300px default size)
#### 5. **DevConsole** (`src/entries/DevConsole/index.tsx`)
Interactive development console for testing TLSN plugins:
- **Code Editor**: CodeMirror with JavaScript syntax highlighting and one-dark theme
- **Live Execution**: Runs plugin code in QuickJS sandbox via background service worker
- **Console Output**: Timestamped entries showing execution results, errors, and timing
- **ExtensionAPI**: Exposes `window.tlsn.execCode()` method for plugin execution
- Access: Right-click context menu → "Developer Console"
**Plugin Structure:**
Plugins must export:
- `config`: Metadata (`name`, `description`)
- `main()`: Reactive UI rendering function (called when state changes)
- `onClick()`: Click handler for proof generation
- React-like hooks: `useHeaders()`, `useEffect()`, `useRequests()`
- UI components: `div()`, `button()` returning DOM JSON
- Capabilities: `openWindow()`, `prove()`, `done()`
#### 6. **Offscreen Document** (`src/entries/Offscreen/index.tsx`)
Isolated React component for background processing:
- **Purpose**: Handles DOM operations unavailable in service workers
- **SessionManager Integration**: Executes plugin code via `SessionManager.executePlugin()`
- **Message Handling**: Listens for `EXEC_CODE` messages from DevConsole
- **Lifecycle**: Created dynamically by background script, reused if exists
- Entry point: `offscreen.html`
### Key Classes
#### **WindowManager** (`src/background/WindowManager.ts`)
Centralized management for multiple browser windows:
- **Window Tracking**: Maintains Map of window ID to ManagedWindow objects
- **Request History**: Each window stores up to 1000 intercepted requests
- **Overlay Control**: Shows/hides TLSN overlay per window with retry logic
- **Lifecycle Management**: Register, close, lookup windows by ID or tab ID
- **Window Limits**: Enforces maximum of 10 managed windows
- **Auto-cleanup**: Removes invalid windows on periodic intervals
Key methods:
- `registerWindow(config)`: Create new managed window with UUID
- `addRequest(windowId, request)`: Add intercepted request to window
- `showOverlay(windowId)`: Display request overlay (with retry)
- `cleanupInvalidWindows()`: Remove closed windows from tracking
#### **SessionManager** (`src/offscreen/SessionManager.ts`)
Plugin session management with TLSNotary proof generation:
- Uses `@tlsn/plugin-sdk` Host class for sandboxed plugin execution
- Provides unified `prove()` capability to plugins via QuickJS environment
- Integrates with `ProveManager` for WASM-based TLS proof generation
- Handles HTTP transcript parsing with byte-level range tracking
**Key Capability - Unified prove() API:**
The SessionManager exposes a single `prove()` function to plugins that handles the entire proof pipeline:
1. Creates prover connection to verifier server
2. Sends HTTP request through TLS prover
3. Captures TLS transcript (sent/received bytes)
4. Parses transcript with Parser class for range extraction
5. Applies selective reveal handlers to show only specified data
6. Generates and returns cryptographic proof
**Handler System:**
Plugins control what data is revealed in proofs using Handler objects:
- `type`: `'SENT'` (request data) or `'RECV'` (response data)
- `part`: `'START_LINE'`, `'PROTOCOL'`, `'METHOD'`, `'REQUEST_TARGET'`, `'STATUS_CODE'`, `'HEADERS'`, `'BODY'`
- `action`: `'REVEAL'` (plaintext) or `'PEDERSEN'` (hash commitment)
- `params`: Optional parameters for granular control (e.g., `hideKey`, `hideValue`, `type: 'json'`, `path`)
Example prove() call:
```javascript
const proof = await prove(
{ url: 'https://api.x.com/endpoint', method: 'GET', headers: {...} },
{
verifierUrl: 'http://localhost:7047',
proxyUrl: 'wss://notary.pse.dev/proxy?token=api.x.com',
maxRecvData: 16384,
maxSentData: 4096,
handlers: [
{ type: 'SENT', part: 'START_LINE', action: 'REVEAL' },
{ type: 'RECV', part: 'BODY', action: 'REVEAL',
params: { type: 'json', path: 'screen_name', hideKey: true } }
]
}
);
```
### State Management
Redux store located in `src/reducers/index.tsx`:
- **App State Interface**: `{ message: string, count: number }`
- **Action Creators**:
- `setMessage(message: string)` - Updates message state
- `incrementCount()` - Increments counter
- **Store Configuration** (`src/utils/store.ts`):
- Development: Uses `redux-thunk` + `redux-logger` middleware
- Production: Uses `redux-thunk` only
- **Type Safety**: Exports `RootState` and `AppRootState` types
### Message Passing Architecture
**Page → Extension Flow (Window Opening)**:
```
Page: window.tlsn.open(url)
↓ window.postMessage(TLSN_OPEN_WINDOW)
Content Script: event listener
↓ browser.runtime.sendMessage(OPEN_WINDOW)
Background: WindowManager.registerWindow()
↓ browser.windows.create()
↓ Returns window info
```
**Request Interception Flow**:
```
Browser: HTTP request in managed window
↓ webRequest.onBeforeRequest
Background: WindowManager.addRequest()
↓ browser.tabs.sendMessage(UPDATE_TLSN_REQUESTS)
Content Script: Update overlay UI
```
**Plugin UI Re-rendering Flow**:
```
Content Script: Loads in managed window
↓ browser.runtime.sendMessage(CONTENT_SCRIPT_READY)
Background: Receives CONTENT_SCRIPT_READY
↓ WindowManager.reRenderPluginUI(windowId)
↓ SessionManager calls main(true) to force re-render
↓ browser.tabs.sendMessage(RE_RENDER_PLUGIN_UI)
Content Script: Renders plugin UI from DOM JSON
```
**Multi-Window Management**:
- Each window has unique UUID and separate request history
- Overlay updates are sent only to the specific window's tab
- Windows are tracked by both Chrome window ID and tab ID
- Maximum 10 concurrent managed windows
**Security**:
- Content script validates origin (`event.origin === window.location.origin`)
- URL validation using `validateUrl()` utility before window creation
- Request interception limited to managed windows only
### TLSN Overlay Feature
The overlay is a full-screen modal showing intercepted requests:
- **Design**: Dark gradient background (rgba(0,0,0,0.85)) with glassmorphic message box
- **Content**:
- Header: "TLSN Plugin In Progress" with gradient text
- Request list: Scrollable container showing METHOD + URL for each request
- Request count: Displayed in header
- **Styling**: Inline CSS with animations (fadeInScale), custom scrollbar styling
- **Updates**: Real-time updates as new requests are intercepted
- **Lifecycle**: Created when TLSN window opens, updated via background messages, cleared on window close
### Build Configuration
**Webpack 5 Setup** (`webpack.config.js`):
- **Entry Points**: popup, background, contentScript, content, offscreen
- **Output**: `build/` directory with `[name].bundle.js` pattern
- **Loaders**:
- `ts-loader` - TypeScript compilation (transpileOnly in dev)
- `babel-loader` - JavaScript transpilation with React Refresh
- `style-loader` + `css-loader` + `postcss-loader` + `sass-loader` - Styling pipeline
- `html-loader` - HTML templates

## Development Workflow
1. **Initial Setup** (from repository root):
```bash
npm install # Requires Node.js >= 18
```
2. **Development Mode**:
```bash
npm run dev # Starts webpack-dev-server on port 3000
```
- Hot module replacement enabled
- Files written to `packages/extension/build/` directory
- Load extension in Chrome: `chrome://extensions/` → Developer mode → Load unpacked → Select `build/` folder
3. **Testing Multi-Window Functionality**:
```javascript
// From any webpage with extension loaded:
await window.tlsn.open('https://x.com', { showOverlay: true });
```
- Opens new window with request interception
- Displays overlay showing captured HTTP requests
- Maximum 10 concurrent windows
4. **Production Build**:
```bash
NODE_ENV=production npm run build # Creates zip in packages/extension/zip/
```
5. **Running Tests**:
```bash
npm run test # Run all tests
npm run test:coverage # Generate coverage reports
```
## Plugin SDK Package (`packages/plugin-sdk`)
### Host Class API
The SDK provides a `Host` class for sandboxed plugin execution with capability injection:
```typescript
import Host from '@tlsn/plugin-sdk';
const host = new Host({
onProve: async (requestOptions, proverOptions) => { /* proof generation */ },
onRenderPluginUi: (windowId, domJson) => { /* render UI */ },
onCloseWindow: (windowId) => { /* cleanup */ },
onOpenWindow: async (url, options) => { /* open window */ },
});
// Execute plugin code
await host.executePlugin(pluginCode, { eventEmitter });
```
**Capabilities injected into plugin environment:**
- `prove(requestOptions, proverOptions)`: Unified TLS proof generation
- `openWindow(url, options)`: Open managed browser windows
- `useHeaders(filter)`: Subscribe to intercepted HTTP headers
- `useRequests(filter)`: Subscribe to intercepted HTTP requests
- `useEffect(callback, deps)`: React-like side effects
- `useState(key, defaultValue)`: Get state value (returns current value or default)
- `setState(key, value)`: Set state value (triggers UI re-render)
- `div(options, children)`: Create div DOM elements
- `button(options, children)`: Create button DOM elements
- `done(result)`: Complete plugin execution
**State Management Example:**
```javascript
function main() {
const count = useState('counter', 0);
return div({}, [
div({}, [`Count: ${count}`]),
button({ onclick: 'handleClick' }, ['Increment'])
]);
}
async function handleClick() {
const count = useState('counter', 0);
setState('counter', count + 1);
}
```
### Parser Class
HTTP message parser with byte-level range tracking:
```typescript
import { Parser } from '@tlsn/plugin-sdk';
const parser = new Parser(httpTranscript);
const json = parser.json();
// Extract byte ranges for selective disclosure
const ranges = parser.ranges.body('screen_name', { type: 'json', hideKey: true });
```
**Features:**
- Parse HTTP requests and responses
- Handle chunked transfer encoding
- Extract header ranges with case-insensitive names
- Extract JSON field ranges (top-level only)
- Regex-based body pattern matching
- Track byte offsets for TLSNotary selective disclosure
**Limitations:**
- Nested JSON field access (e.g., `"user.profile.name"`) not yet supported
- Multi-chunk responses map to first chunk's offset only
### QuickJS Sandboxing
- Uses `@sebastianwessel/quickjs` for secure JavaScript execution
- Plugins run in isolated WebAssembly environment
- Network and filesystem access disabled by default
- Host controls available capabilities through `env` object
- Reactive rendering: `main()` function called whenever hook state changes
- Force re-render: `main(true)` can be called to force UI re-render even if state hasn't changed (used on content script initialization)
### Build Configuration
- **Vite**: Builds isomorphic package for Node.js and browser
- **TypeScript**: Strict mode with full type declarations
- **Testing**: Vitest with coverage reporting
- **Output**: ESM module in `dist/` directory
## Verifier Server Package (`packages/verifier`)
Rust-based HTTP/WebSocket server for TLSNotary verification:
**Architecture:**
- Built with Axum web framework
- WebSocket endpoints for prover-verifier communication
- Session management with UUID-based tracking
- CORS enabled for cross-origin requests
- Webhook system for external service notifications
**Endpoints:**
- `GET /health` → Health check (returns "ok")
- `WS /session` → Create new verification session
- `WS /verifier?sessionId=<id>` → WebSocket verification endpoint
- `WS /proxy?token=<host>` → WebSocket proxy for TLS connections (compatible with notary.pse.dev)
**Configuration:**
- Default port: `7047`
- Configurable max sent/received data sizes
- Request timeout handling
- Tracing with INFO level logging
- YAML configuration file (`config.yaml`) for webhooks
**Webhook Configuration (`config.yaml`):**
```yaml
webhooks:
# Per-server webhooks
"api.x.com":
url: "https://your-backend.example.com/webhook/twitter"
headers:
Authorization: "Bearer your-secret-token"
X-Source: "tlsn-verifier"
# Wildcard for unmatched servers
"*":
url: "https://your-backend.example.com/webhook/default"
```
Webhooks receive POST requests with:
- Session info (ID, custom data)
- Redacted transcripts (only revealed ranges visible)
- Reveal configuration
**Running the Server:**
```bash
cd packages/verifier
cargo run # Development
cargo build --release # Production
cargo test # Tests
```
**Session Flow:**
1. Extension creates session via `/session` WebSocket
2. Server returns `sessionId` and waits for verifier connection
3. Extension connects to `/verifier?sessionId=<id>`
4. Prover sends HTTP request through `/proxy?token=<host>`
5. Verifier validates TLS handshake and transcript
6. Server returns verification result with transcripts
7. If webhook configured, sends POST to configured endpoint (fire-and-forget)
## Common Package (`packages/common`)
Shared utilities used by extension and plugin-sdk:
**Logger System:**
Centralized logging with configurable levels:
```typescript
import { logger, LogLevel } from '@tlsn/common';
// Initialize with log level
logger.init(LogLevel.DEBUG);
// Log at different levels
logger.debug('Detailed debug info');
logger.info('Informational message');
logger.warn('Warning message');
logger.error('Error message');
// Change level at runtime
logger.setLevel(LogLevel.WARN);
```
**Log Levels:**
- `DEBUG` (0) - Most verbose, includes all messages
- `INFO` (1) - Informational messages and above
- `WARN` (2) - Warnings and errors only
- `ERROR` (3) - Errors only
**Output Format:**
```
[HH:MM:SS] [LEVEL] message
```
## Demo Package (`packages/demo`)
Docker-based demo environment for testing plugins:
**Files:**
- `twitter.js`, `swissbank.js` - Example plugin files
- `docker-compose.yml` - Docker services configuration
- `nginx.conf` - Reverse proxy configuration
- `start.sh` - Setup script with URL templating
**Docker Services:**
1. `verifier` - TLSNotary verifier server (port 7047)
2. `demo-static` - nginx serving static plugin files
3. `nginx` - Reverse proxy (port 80)
**Environment Variables:**
- `VERIFIER_HOST` - Verifier server host (default: `localhost:7047`)
- `SSL` - Use https/wss protocols (default: `false`)
**Usage:**
```bash
# Local development
./start.sh
# Production with SSL
VERIFIER_HOST=verifier.tlsnotary.org SSL=true ./start.sh
# Docker detached mode
./start.sh -d
```
The `start.sh` script:
1. Processes plugin files, replacing `verifierUrl` and `proxyUrl` placeholders
2. Copies processed files to `generated/` directory
3. Starts Docker Compose services
## Important Implementation Notes
### Plugin API Changes
The plugin API uses a **unified `prove()` function** instead of separate functions. The old API (`createProver`, `sendRequest`, `transcript`, `reveal`, `getResponse`) has been removed.
**Current API:**
```javascript
const proof = await prove(requestOptions, proverOptions);
```
**Handler Parameter:**
Note that the parameter name is `handlers` (plural), not `reveal`:
```javascript
proverOptions: {
verifierUrl: 'http://localhost:7047',
proxyUrl: 'wss://...',
maxRecvData: 16384,
maxSentData: 4096,
handlers: [/* handler objects */] // NOT 'reveal'
}
```
### DevConsole Default Template
The default plugin code in `DevConsole/index.tsx` is heavily commented to serve as educational documentation. When modifying, maintain the comprehensive inline comments explaining:
- Each step of the proof generation flow
- Purpose of each header and parameter
- What each reveal handler does
- How React-like hooks work
### Test Data Sanitization
Parser tests (`packages/plugin-sdk/src/parser.test.ts`) use redacted sensitive data:
- Authentication tokens: `REDACTED_BEARER_TOKEN`, `REDACTED_CSRF_TOKEN_VALUE`
- Screen names: `test_user` (not real usernames)
- Cookie values: `REDACTED_GUEST_ID`, `REDACTED_COOKIE_VALUE`
### Known Issues
⚠️ **Legacy Code Warning**: `src/entries/utils.ts` contains imports from non-existent files:
- `Background/rpc.ts` (removed in refactor)
- `SidePanel/types.ts` (removed in refactor)
- Functions: `pushToRedux()`, `openSidePanel()`, `waitForEvent()`
- **Status**: Dead code, not used by current entry points
- **Action**: Remove this file or refactor if functionality needed
## Websockify Integration
Used for WebSocket proxying of TLS connections:
**Build Websockify Docker Image**:
```bash
git clone https://github.com/novnc/websockify && cd websockify
./docker/build.sh
```
**Run Websockify**:
```bash
# For x.com (Twitter)
docker run -it --rm -p 55688:80 novnc/websockify 80 api.x.com:443
# For Twitter (alternative)
docker run -it --rm -p 55688:80 novnc/websockify 80 api.twitter.com:443
```
Purpose: Proxies HTTPS connections through WebSocket for browser-based TLS operations.
## Code Quality
**ESLint Configuration** (`.eslintrc`):
- Extends: `prettier`, `@typescript-eslint/recommended`
- Parser: `@typescript-eslint/parser`
- Rules:
- `prettier/prettier`: error
- `@typescript-eslint/no-explicit-any`: warning
- `@typescript-eslint/no-var-requires`: off (allows require in webpack config)
- `@typescript-eslint/ban-ts-comment`: off
- `no-undef`: error
- `padding-line-between-statements`: error
- Environment: `webextensions`, `browser`, `node`, `es6`
- Ignores: `node_modules`, `zip`, `build`, `wasm`, `tlsn`, `webpack.config.js`
**Prettier Configuration** (`.prettierrc.json`):
- Single quotes, trailing commas, 2-space indentation
- Ignore: `.prettierignore` (not in repo, likely default ignores)

## Architecture Overview
### Extension Architecture
The extension uses a message-passing architecture with five main entry points:
```
┌─────────────────────────────────────────────────────────────┐
│ Browser Extension │
│ │
│ ┌──────────────┐ ┌──────────────┐ │
│ │ Background │◄────►│ Content │◄──── Page Scripts │
│ │ (SW) │ │ Script │ │
│ └──────┬───────┘ └──────────────┘ │
│ │ │
│ ├─► Window Management (WindowManager) │
│ ├─► Request Interception (webRequest API) │
│ ├─► Session Management (SessionManager) │
│ └─► Message Routing │
│ │
│ ┌──────────────┐ ┌──────────────┐ │
│ │ DevConsole │ │ Offscreen │ │
│ │ (Editor) │ │ (Background)│ │
│ └──────────────┘ └──────────────┘ │
└─────────────────────────────────────────────────────────────┘
│
▼
┌──────────────┐
│ Verifier │
│ Server │
│ (localhost: │
│ 7047) │
└──────────────┘
```
### Message Flow
**Opening a Managed Window:**
```
Page → window.tlsn.open(url)
↓ window.postMessage(TLSN_OPEN_WINDOW)
Content Script → event listener
↓ browser.runtime.sendMessage(OPEN_WINDOW)
Background → WindowManager.registerWindow()
↓ browser.windows.create()
↓ Returns window info with UUID
```
**Request Interception:**
```
Browser → HTTP request in managed window
↓ webRequest.onBeforeRequest
Background → WindowManager.addRequest()
↓ browser.tabs.sendMessage(UPDATE_TLSN_REQUESTS)
Content Script → Update TLSN overlay UI
```
## Getting Started
### Prerequisites
- **Node.js** >= 18
- **Rust** (for verifier server) - Install from [rustup.rs](https://rustup.rs/)
- **Chrome/Chromium** browser
### Installation
1. Clone the repository:
```bash
git clone https://github.com/tlsnotary/tlsn-extension.git
cd tlsn-extension
```
2. Install all dependencies:
```bash
npm install
```
This installs dependencies for all packages in the monorepo and automatically sets up workspace links between packages.
## Development
### Running the Extension in Development Mode
1. Start the development server:
```bash
npm run dev
```
This automatically builds all dependencies (common, plugin-sdk) and then starts webpack-dev-server on port 3000 with hot module replacement. Files are written to `packages/extension/build/`.
2. Load the extension in Chrome:
- Navigate to `chrome://extensions/`
- Enable "Developer mode" toggle (top right)
- Click "Load unpacked"
- Select the `packages/extension/build/` folder
3. The extension will auto-reload on file changes (manual refresh needed for manifest changes).
### Running the Verifier Server
The verifier server is required for E2E testing. Run it in a separate terminal:
```bash
cd packages/verifier
cargo run
```
The server will start on `http://localhost:7047`.
**Verifier API Endpoints:**
- `GET /health` - Health check
- `WS /session` - Create new verification session
- `WS /verifier?sessionId=<id>` - WebSocket verification endpoint
- `WS /proxy?token=<host>` - WebSocket proxy for TLS connections (compatible with notary.pse.dev)
**Webhook Configuration:**
Configure `packages/verifier/config.yaml` to receive POST notifications after successful verifications:
```yaml
webhooks:
"api.x.com":
url: "https://your-backend.example.com/webhook/twitter"
headers:
Authorization: "Bearer your-secret-token"
"*": # Wildcard for unmatched server names
url: "https://your-backend.example.com/webhook/default"
```
### Package-Specific Development
**Extension:**
```bash
cd packages/extension
npm run dev # Development mode
npm run test # Run tests
npm run test:watch # Watch mode
npm run test:coverage # Coverage report
npm run lint # Lint check
npm run lint:fix # Auto-fix linting issues
```
**Plugin SDK:**
```bash
cd packages/plugin-sdk
npm run build # Build SDK
npm run test # Run tests
npm run lint # Run all linters
npm run lint:fix # Auto-fix issues
```
> **Note:** The plugin-SDK builds automatically when the extension is built, so manual building is usually not necessary.
**Verifier:**
```bash
cd packages/verifier
cargo run # Development mode
cargo build --release # Production build
cargo test # Run tests
```
## Production Build
### Build Extension for Production
From the repository root:
```bash
NODE_ENV=production npm run build
```
This automatically:
1. Builds dependencies (`@tlsn/common` and `@tlsn/plugin-sdk`)
2. Builds the extension with production optimizations
3. Creates:
- Optimized build in `packages/extension/build/`
- Packaged extension in `packages/extension/zip/extension-{version}.zip`
The zip file is ready for Chrome Web Store submission.
**Alternative build commands:**
- `npm run build:extension` - Build only the extension (assumes dependencies are built)
- `npm run build:deps` - Build only the dependencies
### Build All Packages
```bash
npm run build:all
```
This builds all packages in the monorepo (extension, plugin-sdk).
### Build Verifier for Production
```bash
cd packages/verifier
cargo build --release
```
The binary will be in `target/release/`.
## End-to-End Testing
To test the complete TLSN workflow:
### 1. Start the Verifier Server
In a terminal:
```bash
cd packages/verifier
cargo run
```
Verify it's running:
```bash
curl http://localhost:7047/health
# Should return: ok
```
### 2. Start the Extension in Development Mode
In another terminal:
```bash
npm run dev
```
Load the extension in Chrome (see [Getting Started](#getting-started)).
### 3. Open the Developer Console
1. Right-click anywhere on any web page
2. Select "Developer Console" from the context menu
3. A new tab will open with the code editor
### 4. Run a Test Plugin
The Developer Console comes with a default X.com profile prover plugin. To test:
1. Ensure the verifier is running on `localhost:7047`
2. Review the default code in the editor (or modify as needed)
3. Click "▶️ Run Code" button
4. The plugin will:
- Open a new window to X.com
- Intercept requests
- Create a prover connection to the verifier
- Display a UI overlay showing progress
- Execute the proof workflow
**Console Output:**
- Execution status and timing
- Plugin logs and results
- Any errors encountered
### 5. Verify Request Interception
When a managed window is opened:
1. An overlay appears showing "TLSN Plugin In Progress"
2. Intercepted requests are listed in real-time
3. Request count updates as more requests are captured
### Testing Different Plugins
You can write custom plugins in the Developer Console editor:
```javascript
// Example: Simple plugin that generates a proof
const config = {
name: 'My Plugin',
description: 'A custom TLSN plugin'
};
async function onClick() {
console.log('Starting proof...');
// Wait for specific headers to be intercepted
const [header] = useHeaders(headers => {
return headers.filter(h => h.url.includes('example.com'));
});
console.log('Captured header:', header);
// Generate proof using unified prove() API
const proof = await prove(
// Request options
{
url: 'https://example.com/api/endpoint',
method: 'GET',
headers: {
'Authorization': header.requestHeaders.find(h => h.name === 'Authorization')?.value,
'Accept-Encoding': 'identity',
'Connection': 'close',
},
},
// Prover options
{
verifierUrl: 'http://localhost:7047',
proxyUrl: 'wss://notary.pse.dev/proxy?token=example.com',
maxRecvData: 16384,
maxSentData: 4096,
handlers: [
{ type: 'SENT', part: 'START_LINE', action: 'REVEAL' },
{ type: 'RECV', part: 'START_LINE', action: 'REVEAL' },
{ type: 'RECV', part: 'BODY', action: 'REVEAL',
params: { type: 'json', path: 'username' } }
]
}
);
console.log('Proof generated:', proof);
done(JSON.stringify(proof));
}
function main() {
const [header] = useHeaders(headers => {
return headers.filter(h => h.url.includes('example.com'));
});
// Open a managed window on first render
useEffect(() => {
openWindow('https://example.com');
}, []);
// Render plugin UI component
return div({}, [
div({}, [header ? 'Ready to prove' : 'Waiting for headers...']),
header ? button({ onclick: 'onClick' }, ['Generate Proof']) : null
]);
}
export default {
main,
onClick,
config,
};
```
### Testing Tips
- **Monitor Background Service Worker**: Open Chrome DevTools for the background service worker via `chrome://extensions/` → Extension Details → "Inspect views: service worker"
- **Check Console Logs**: Look for WindowManager logs, request interception logs, and message routing logs
- **Test Multiple Windows**: Try opening multiple managed windows simultaneously (max 10)
- **Verifier Connection**: Ensure verifier is accessible at `localhost:7047` before running proofs
## Running the Demo
The demo package provides a complete environment for testing TLSNotary plugins.
### Quick Start with Docker
```bash
# Start all services (verifier + demo server)
npm run docker:up
# Stop services
npm run docker:down
```
This starts:
- Verifier server on port 7047
- Demo static files served via nginx on port 80
### Manual Demo Setup
```bash
# Serve demo files locally
npm run demo
# Open http://localhost:8080 in your browser
```
### Environment Variables
Configure the demo for different environments:
```bash
# Local development (default)
./packages/demo/start.sh
# Production with SSL
VERIFIER_HOST=verifier.tlsnotary.org SSL=true ./packages/demo/start.sh
```
### Tutorial
```bash
# Serve tutorial examples
npm run tutorial
# Open http://localhost:8080 in your browser
```
## Websockify Integration
For WebSocket proxying of TLS connections (optional):
### Build Websockify Docker Image
```bash
git clone https://github.com/novnc/websockify && cd websockify
./docker/build.sh
```
### Run Websockify
```bash
# For X.com
docker run -it --rm -p 55688:80 novnc/websockify 80 api.x.com:443
# For Twitter
docker run -it --rm -p 55688:80 novnc/websockify 80 api.twitter.com:443
```
This proxies HTTPS connections through WebSocket for browser-based TLS operations.
## Publishing
### Chrome Web Store
1. Create a production build:
```bash
NODE_ENV=production npm run build
```
2. Test the extension thoroughly
3. Upload `packages/extension/zip/extension-{version}.zip` to [Chrome Web Store Developer Dashboard](https://chrome.google.com/webstore/devconsole)
4. Follow the [Chrome Web Store publishing guide](https://developer.chrome.com/webstore/publish)
### Pre-built Extension
The easiest way to install the TLSN browser extension is from the [Chrome Web Store](https://chromewebstore.google.com/detail/tlsn-extension/gcfkkledipjbgdbimfpijgbkhajiaaph).
## Resources
- [TLSNotary Documentation](https://docs.tlsnotary.org/)
- [Webpack Documentation](https://webpack.js.org/concepts/)
- [Chrome Extension Documentation](https://developer.chrome.com/docs/extensions/)
- [Manifest V3 Migration Guide](https://developer.chrome.com/docs/extensions/mv3/intro/)
- [webextension-polyfill](https://github.com/mozilla/webextension-polyfill)

at your option.
## Installing and Running
The easiest way to install the TLSN browser extension is to use the [Chrome Web Store](https://chromewebstore.google.com/detail/tlsn-extension/gcfkkledipjbgdbimfpijgbkhajiaaph).
You can also build and run it locally as explained in the following steps.
### Procedure:
1. Check if your [Node.js](https://nodejs.org/) version is >= **18**.
2. Clone this repository.
3. Run `npm install` to install the dependencies.
4. Run `npm run dev`
5. Load your extension on Chrome following:
1. Access `chrome://extensions/`
2. Check `Developer mode`
3. Click on `Load unpacked extension`
4. Select the `build` folder.
6. Happy hacking.
## Building Websockify Docker Image
```
$ git clone https://github.com/novnc/websockify && cd websockify
$ ./docker/build.sh
$ docker run -it --rm -p 55688:80 novnc/websockify 80 api.x.com:443
```
## Running Websockify Docker Image
```
$ cd tlsn-extension
$ docker run -it --rm -p 55688:80 novnc/websockify 80 api.twitter.com:443
```
## Packing
After the development of your extension run the command
```
$ NODE_ENV=production npm run build
```
Now, the content of `build` folder will be the extension ready to be submitted to the Chrome Web Store. Just take a look at the [official guide](https://developer.chrome.com/webstore/publish) to more infos about publishing.

This folder contains a basic demo for running TLSNotary plugins.
The demo needs the TLSNotary extension to run the plugins in your browser.
In this demo, the plugins prove data from a server (e.g. Twitter). Of course you will also need the verifier counterpart. In this demo we will use the verifier server from the `packages/verifier` folder.
Prerequisites:
* Chromium browser
* internet connection
To run this demo:
1. Install the browser extension
2. Launch the verification server
3. A web socket proxy
4. Launch the demo
## 1. Install the browser extension
### Install from the Google Web Store
TODO
### Build from source
1. In this repository's main folder, run:
```sh
npm ci
npm run build
```
This builds the extension in the `packages/extension/build/` folder.
2. Next load the extension in Chrome:
* Navigate to `chrome://extensions/`
* Enable **Developer mode** toggle (top right)
* Click **Load unpacked**
* Select the `packages/extension/build/` folder
The extension is now installed
## 2. Launch the verifier server
Launch the verifier server
```sh
cd packages/verifier
cargo run --release
```
## 3. Websocket proxy
In the TLSNotary protocol the prover connects directly to the server serving the data. The prover sets up a TCP connection and to the server this looks like any other connection. Unfortunately, browsers do not offer the functionally to let browser extensions setup TCP connections. A workaround is to connect to a websocket proxy that sets up the TCP connection instead.
You can use the websocketproxy hosted by the TLSNotary team, or run your own proxy:
* TLSNotary proxy: `wss://notary.pse.dev/proxy?token=host`,
* Run a local proxy:
1. Install [wstcp](https://github.com/sile/wstcp):
```shell
cargo install wstcp
```
1. Run a websocket proxy for `https://<host>`:
```shell
wstcp --bind-addr 127.0.0.1:55688 <host>:443
```
## 4. Launch the demo
Run the demo with `npm run demo`.
You can now open the demo by opening http://localhost:8080 in your browser with the TLSNotary extension

TLSNotary is a zkTLS protocol that allows a prover to prove web data from a web server to a third-party verifier. In most zkTLS use cases, a web app wants to provide an end user with a service that requires verifiable private user data.
In this tutorial, you will learn how to build a small website that provides visitors a way to prove their bank balance to a verifier backend. This will give you cryptographic guarantees of the bank balance of the user/prover. In this tutorial, we will write a plugin for the TLSNotary browser extension to prove the balance of the user on their Swiss bank. The extension will run this plugin and ensure the user is protected while providing you an easy way to verify the proven data. You will also run a verifier server that verifies user proofs. Note that in this tutorial we will not do post-processing of the proven data. In a real-world scenario, you would of course check the bank balance and verify it meets the requirements for whatever next step your application needs.
Prerequisites:
* npm
* cargo (Rust)
* Clone this repository
* Google Chrome browser
1. Install the TLSNotary extension
TODO: add extension URL
2. Launch the verifier
```
cd verifier
cargo run --release
```
3. ~~Test the Twitter example → prove screen name~~
4. Try to access the bank balance without logging in: https://swissbank.tlsnotary.org/balances → you should get an error
5. Log in to the bank: https://swissbank.tlsnotary.org/login
1. Username: "tkstanczak"
2. Password: "TLSNotary is my favorite project"
6. Modify the Twitter plugin to get the balance information instead:
1. Modify all URLs
2. Modify the information that will be revealed (the "CHF" balance)
7. Run the plugin
# Extra challenge: "Fool the verifier"
So far we have focused on the prover only. Verification is of course also extremely important. You always have to carefully verify the data you receive from users. Even if it is cryptographically proven with TLSNotary, you still have to verify the data correctly, or you can be fooled.
In this extra challenge, you should examine how the verifier checks the balance and modify the prover to make the verifier believe you have more CHF in your bank account than you actually do.
Hint
* Look how naive the check is for "swissbank.tlsnotary.org" in `packages/verifier/main.rs`
* Manipulate the existing regex in the prover and add an extra entry to prove a different number
<TODO: Screenshot CHF 275_000_000>
FAQ:
Browser only? For now, yes. In a few months, you will be able to run the plugins on mobile too. #pinkypromise

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Commands
### Development
- `npm install` - Install dependencies
- `npm run dev` - Start webpack dev server with hot reload on port 3000 (default)
- `npm run build` - Build extension (uses NODE_ENV from utils/build.js, defaults to production)
- `npm run build:webpack` - Direct webpack build with production mode
- `npm run lint` - Run ESLint to check code quality
- `npm run lint:fix` - Run ESLint with auto-fix for issues
## TLSNotary Extension
This is a Chrome Extension (Manifest V3) for TLSNotary, enabling secure notarization of TLS data. The extension was recently refactored (commit 92ecb55) to a minimal boilerplate, with TLSN overlay functionality being incrementally added back.
**Important**: The extension must match the version of the notary server it connects to.
## Architecture Overview
### Extension Entry Points
The extension has 5 main entry points defined in `webpack.config.js`:
#### 1. **Background Service Worker** (`src/entries/Background/index.ts`)
Core responsibilities:
- **TLSN Window Management**: Creates popup windows for TLSN operations, tracks window/tab IDs
- **Request Interception**: Uses `webRequest.onBeforeRequest` API to intercept all HTTP requests from TLSN windows
- **Request Storage**: Maintains in-memory array of intercepted requests (`tlsnRequests`)
- **Message Routing**: Forwards messages between content scripts, popup, and injected page scripts
- **Offscreen Document Management**: Creates offscreen documents for background DOM operations (Chrome 109+)
- Uses `webextension-polyfill` for cross-browser compatibility
Key message handlers:
- `PING` → `PONG` (connectivity test)
- `TLSN_CONTENT_TO_EXTENSION` → Opens new popup window, tracks requests
- `CONTENT_SCRIPT_READY` → Confirms content script loaded
#### 2. **Content Script** (`src/entries/Content/index.ts`)
Injected into all HTTP/HTTPS pages via manifest. Responsibilities:
- **Script Injection**: Injects `content.bundle.js` into page context to expose page-accessible API
- **TLSN Overlay Management**: Creates/updates full-screen overlay showing intercepted requests
- **Message Bridge**: Bridges messages between page scripts and extension background
- **Request Display**: Real-time updates of intercepted requests in overlay UI
Message handlers:
- `GET_PAGE_INFO` → Returns page title, URL, domain
- `SHOW_TLSN_OVERLAY` → Creates overlay with initial requests
- `UPDATE_TLSN_REQUESTS` → Updates overlay with new requests
- `HIDE_TLSN_OVERLAY` → Removes overlay and clears state
Window message handler:
- Listens for `TLSN_CONTENT_SCRIPT_MESSAGE` from page scripts
- Forwards to background via `TLSN_CONTENT_TO_EXTENSION`
#### 3. **Content Module** (`src/entries/Content/content.ts`)
Injected script running in page context (not content script context):
- **Page API**: Exposes `window.extensionAPI` object to web pages
- **Message Bridge**: Provides `sendMessage()` method that posts messages via `window.postMessage`
- **Lifecycle Event**: Dispatches `extension_loaded` custom event when ready
- **Web Accessible Resource**: Listed in manifest's `web_accessible_resources`
Page API usage:
```javascript
window.extensionAPI.sendMessage({ action: 'startTLSN' });
window.addEventListener('extension_loaded', () => { /* ready */ });
```
#### 4. **Popup UI** (`src/entries/Popup/index.tsx`)
React-based extension popup:
- **Simple Interface**: "Hello World" boilerplate with test button
- **Redux Integration**: Connected to Redux store via `react-redux`
- **Message Sending**: Can send messages to background script
- **Styling**: Uses Tailwind CSS with custom button/input classes
- Entry point: `popup.html` (400x300px default size)
#### 5. **Offscreen Document** (`src/entries/Offscreen/index.tsx`)
Isolated React component for background processing:
- **Purpose**: Handles DOM operations unavailable in service workers
- **Message Handling**: Listens for `PROCESS_DATA` messages (example implementation)
- **Lifecycle**: Created dynamically by background script, reused if exists
- Entry point: `offscreen.html`
### State Management
Redux store located in `src/reducers/index.tsx`:
- **App State Interface**: `{ message: string, count: number }`
- **Action Creators**:
- `setMessage(message: string)` - Updates message state
- `incrementCount()` - Increments counter
- **Store Configuration** (`src/utils/store.ts`):
- Development: Uses `redux-thunk` + `redux-logger` middleware
- Production: Uses `redux-thunk` only
- **Type Safety**: Exports `RootState` and `AppRootState` types
### Message Passing Architecture
**Page → Extension Flow**:
```
Page (window.postMessage)
↓
Content Script (window.addEventListener('message'))
↓
Background (browser.runtime.sendMessage)
```
**Extension → Page Flow**:
```
Background (browser.tabs.sendMessage)
↓
Content Script (browser.runtime.onMessage)
↓
Page DOM manipulation (overlay, etc.)
```
**Security**: Content script only accepts messages from same origin (`event.origin === window.location.origin`)
### TLSN Overlay Feature
The overlay is a full-screen modal showing intercepted requests:
- **Design**: Dark gradient background (rgba(0,0,0,0.85)) with glassmorphic message box
- **Content**:
- Header: "TLSN Plugin In Progress" with gradient text
- Request list: Scrollable container showing METHOD + URL for each request
- Request count: Displayed in header
- **Styling**: Inline CSS with animations (fadeInScale), custom scrollbar styling
- **Updates**: Real-time updates as new requests are intercepted
- **Lifecycle**: Created when TLSN window opens, updated via background messages, cleared on window close
### Build Configuration
**Webpack 5 Setup** (`webpack.config.js`):
- **Entry Points**: popup, background, contentScript, content, offscreen
- **Output**: `build/` directory with `[name].bundle.js` pattern
- **Loaders**:
- `ts-loader` - TypeScript compilation (transpileOnly in dev)
- `babel-loader` - JavaScript transpilation with React Refresh
- `style-loader` + `css-loader` + `postcss-loader` + `sass-loader` - Styling pipeline
- `html-loader` - HTML templates
- `asset/resource` - File assets (images, fonts)
- **Plugins**:
- `ReactRefreshWebpackPlugin` - Hot module replacement (dev only)
- `CleanWebpackPlugin` - Cleans build directory
- `CopyWebpackPlugin` - Copies manifest, icons, CSS files
- `HtmlWebpackPlugin` - Generates popup.html and offscreen.html
- `TerserPlugin` - Code minification (production only)
- **Dev Server** (`utils/webserver.js`):
- Port: 3000 (configurable via `PORT` env var)
- Hot reload enabled with `webpack/hot/dev-server`
- Writes to disk for Chrome to load (`writeToDisk: true`)
- WebSocket transport for HMR
**Production Build** (`utils/build.js`):
- Adds `ZipPlugin` to create `tlsn-extension-{version}.zip` in `zip/` directory
- Uses package.json version for naming
- Exits with code 1 on errors or warnings
### Extension Permissions
Defined in `src/manifest.json`:
- `offscreen` - Create offscreen documents for background processing
- `webRequest` - Intercept HTTP/HTTPS requests
- `storage` - Persistent local storage
- `activeTab` - Access active tab information
- `tabs` - Tab management (create, query, update)
- `windows` - Window management (create, track, remove)
- `host_permissions: ["<all_urls>"]` - Access all URLs for request interception
- `content_scripts` - Inject into all HTTP/HTTPS pages
- `web_accessible_resources` - Make content.bundle.js, CSS, and icons accessible to pages
- `content_security_policy` - Allow WASM execution (`wasm-unsafe-eval`)
### TypeScript Configuration
**tsconfig.json**:
- Target: `esnext`
- Module: `esnext` with Node resolution
- Strict mode enabled
- JSX: React (not React 17+ automatic runtime)
- Includes: `src/` only
- Excludes: `build/`, `node_modules/`
- Types: `chrome` (for Chrome extension APIs)
**Type Declarations**:
- `src/global.d.ts` - Declares PNG module types
- Uses `@types/chrome`, `@types/webextension-polyfill`, `@types/react`, etc.
### Styling
**Tailwind CSS**:
- Configuration: `tailwind.config.js`
- Content: Scans all `src/**/*.{js,jsx,ts,tsx}`
- Custom theme: Primary color `#243f5f`
- PostCSS pipeline with `postcss-preset-env`
**SCSS**:
- FontAwesome integration (all icon sets: brands, solid, regular)
- Custom utility classes: `.button`, `.input`, `.select`, `.textarea`
- BEM-style modifiers: `.button--primary`
- Tailwind @apply directives mixed with custom styles
**Popup Dimensions**:
- Default: 480x600px (set in index.scss body styles)
- Customizable via inline styles or props
## Development Workflow
1. **Initial Setup**:
```bash
npm install # Requires Node.js >= 18
```
2. **Development Mode**:
```bash
npm run dev # Starts webpack-dev-server on port 3000
```
- Hot module replacement enabled
- Files written to `build/` directory
- Source maps: `cheap-module-source-map`
3. **Load Extension in Chrome**:
- Navigate to `chrome://extensions/`
- Enable "Developer mode" toggle
- Click "Load unpacked"
- Select the `build/` folder
- Extension auto-reloads on file changes (requires manual refresh for manifest changes)
4. **Testing TLSN Functionality**:
- Trigger `TLSN_CONTENT_TO_EXTENSION` message from a page using `window.extensionAPI.sendMessage()`
- Background script opens popup window to x.com
- All requests in that window are intercepted and displayed in overlay
5. **Production Build**:
```bash
NODE_ENV=production npm run build # Creates build/ and zip/
```
- Minified output with Terser
- No source maps
- Creates versioned zip file for Chrome Web Store submission
6. **Linting**:
```bash
npm run lint # Check for issues
npm run lint:fix # Auto-fix issues
```
## Known Issues & Legacy Code
⚠️ **Legacy Code Warning**: `src/entries/utils.ts` contains imports from non-existent files:
- `Background/rpc.ts` (removed in refactor)
- `SidePanel/types.ts` (removed in refactor)
- Functions: `pushToRedux()`, `openSidePanel()`, `waitForEvent()`
- **Status**: Dead code, not used by current entry points
- **Action**: Remove this file or refactor if functionality needed
## Websockify Integration
Used for WebSocket proxying of TLS connections:
**Build Websockify Docker Image**:
```bash
git clone https://github.com/novnc/websockify && cd websockify
./docker/build.sh
```
**Run Websockify**:
```bash
# For x.com (Twitter)
docker run -it --rm -p 55688:80 novnc/websockify 80 api.x.com:443
# For Twitter (alternative)
docker run -it --rm -p 55688:80 novnc/websockify 80 api.twitter.com:443
```
Purpose: Proxies HTTPS connections through WebSocket for browser-based TLS operations.
## Code Quality
**ESLint Configuration** (`.eslintrc`):
- Extends: `prettier`, `@typescript-eslint/recommended`
- Parser: `@typescript-eslint/parser`
- Rules:
- `prettier/prettier`: error
- `@typescript-eslint/no-explicit-any`: warning
- `@typescript-eslint/no-var-requires`: off (allows require in webpack config)
- `@typescript-eslint/ban-ts-comment`: off
- `no-undef`: error
- `padding-line-between-statements`: error
- Environment: `webextensions`, `browser`, `node`, `es6`
- Ignores: `node_modules`, `zip`, `build`, `wasm`, `tlsn`, `webpack.config.js`
**Prettier Configuration** (`.prettierrc.json`):
- Single quotes, trailing commas, 2-space indentation
- Ignore: `.prettierignore` (not in repo, likely default ignores)
## Publishing
After building:
1. Test extension thoroughly in Chrome
2. Create production build: `NODE_ENV=production npm run build`
3. Upload `zip/tlsn-extension-{version}.zip` to Chrome Web Store
4. Follow [Chrome Web Store publishing guide](https://developer.chrome.com/webstore/publish)

* 3. Call prove() with the request configuration and reveal handlers
* 4. prove() internally:
* - Creates a prover connection to the verifier
* - Sends the HTTP request through the TLS prover
* - Captures the TLS transcript (sent/received bytes)
* - Parses the transcript with byte-level range tracking
* - Applies selective reveal handlers to show only specified data
* - Generates and returns the cryptographic proof
* 5. Return the proof result to the caller via done()
