Example: Crypt2.ClearEncryptCerts method

Demonstrates how to call the ClearEncryptCerts method. React Native

import { BinData, Cert, Crypt2 } from '@chilkat/react-native'

function chilkatExample() {
  const crypt = new Crypt2();

  // Tell the crypt object to use 3 certificates.
  // Do this by calling AddEncryptCert for each certificate.

  const cert1 = new Cert();
  // ...
  // Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
  // ...
  crypt.addEncryptCert(cert1);

  const cert2 = new Cert();
  // ...
  crypt.addEncryptCert(cert2);

  const cert3 = new Cert();
  // ...
  crypt.addEncryptCert(cert3);

  // Params for public-key encryption to create PKCS7 enveloped-data
  crypt.cryptAlgorithm = 'pki';
  crypt.pkcs7CryptAlg = 'aes';
  crypt.keyLength = 256;
  crypt.oaepHash = 'sha256';
  crypt.oaepPadding = true;

  const bd = new BinData();
  // ...
  crypt.encryptBd(bd);

  // Let's say we now want to encrypt something else with different certs..
  // First clear the encryption certs.
  crypt.clearEncryptCerts();

  const cert4 = new Cert();
  // ...
  crypt.addEncryptCert(cert4);

  const cert5 = new Cert();
  // ...
  crypt.addEncryptCert(cert5);

  // ...
  // ...

  // Encrypt using cert4 and cert5.
  crypt.encryptBd(bd);
