Data Sealing

This feature allows you to encrypt an object, turning it into a sealed string. This string can then be safely transmitted or stored, with the assurance that it cannot be tampered with without detection.

const Iron = require('@hapi/iron');

async function sealData() {
  const object = { a: 1, b: 2, c: 3 };
  const password = 'some-not-very-secret-password';
  const sealed = await Iron.seal(object, password, Iron.defaults);
  console.log(sealed);
}

sealData();

Data Unsealing

This feature allows you to decrypt a previously sealed string, returning it to its original object form. This is crucial for accessing the data in a secure manner after it has been transmitted or stored.

const Iron = require('@hapi/iron');

async function unsealData(sealed) {
  const password = 'some-not-very-secret-password';
  const unsealed = await Iron.unseal(sealed, password, Iron.defaults);
  console.log(unsealed);
}

// Assume 'sealed' is obtained from the sealData function
// unsealData(sealed);
