Encrypt a JWE with a Password (PBES2)

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPassword, which sets the PBES2 password for a recipient. The example uses PBES2-HS256+A128KW key management with AES-128-GCM content encryption.

import { JsonObject, Jwe } from '@chilkat/react-native'

function chilkatExample() {
  const jwe = new Jwe();

  // Protected header: PBES2 password-based key management with AES-128-GCM content encryption.
  const header = new JsonObject();
  header.updateString('alg', 'PBES2-HS256+A128KW');
  header.updateString('enc', 'A128GCM');
  try {
    jwe.setProtectedHeader(header);
  } catch {
    console.log(jwe.lastErrorText);
    return;
  }

  // Set the PBES2 password for recipient 0.  The password should come from a secure source rather than
  // being hard-coded.
  const password = 'myPassword';
  try {
    jwe.setPassword(0, password);
  } catch {
    console.log(jwe.lastErrorText);
    return;
  }

  let jweCompact: string;
  try {
    jweCompact = jwe.encrypt('This is the secret content.', 'utf-8');
  } catch {
    console.log(jwe.lastErrorText);
    return;
  }

  console.log(jweCompact);
