Examples

Complete session workflow (Create → Verify)

import { allowSessionTimeWalletWithJWT, verifySessionTimeWalletWithJWT } from "dacc-js";
 
// Step 1: Create session token from encrypted wallet
const sessionJWT = await allowSessionTimeWalletWithJWT({
  daccPublickey: 'daccPublickey_0x123_XxX..',
  passwordSecretkey: 'my+Password#123..',
  jwtSecret: 'jwt-secret-to-app',
  maxAgeSeconds: 3600 // 1 hour
});
 
console.log(`Session created: ${sessionJWT}`); // eyJhZGRyZXNz...
 
// Step 2: Later, verify the session token
const walletJWT = await verifySessionTimeWalletWithJWT({
  jwt: sessionJWT,
  jwtSecret: 'jwt-secret-to-app'
});
 
if (walletJWT) {
  console.log(`Address: ${walletJWT.address}`); // 0x123...
