• APDU Transfers: Sends raw ISO/IEC 7816-4 compliant Command/Response APDU packets.
• Zero Dependencies: Pure vanilla JavaScript module.

Usage Example

import { requestTokenDevice, computeTokenSignature } from '@dottedice/dsc-token-bridge';

// 1. Prompt user to select USB Token device
const device = await requestTokenDevice();
console.log('Connected to:', device.productName);

// 2. Compute signature using token hardware
const digest = new Uint8Array([1, 2, 3, 4]); // digest to sign
const signature = await computeTokenSignature(device, digest);
console.log('Signature computed:', signature);
