How to start using jsrsasign CDN


// Include the jsrsasign library
const KJUR = document.createElement('script');
KJUR.src = 'https://cdn.cdnhub.io/jsrsasign/11.1.0/jsrsasign-all-min.js';
document.head.appendChild(KJUR);

// Wait for the library to be loaded
window.onload = () => {
  const jsrsasign = window.kjur;

  // Generate an RSA key pair
  const keySize = 2048;
  const rsaKeyPair = jsrsasign.KJUR.crypto.KeyPairGenerator.RSA.generateKeyPair(keySize);

  // Extract the public and private keys
  const publicKey = rsaKeyPair.publicKeyInfo.module.exports();
  const privateKey = rsaKeyPair.privateKeyInfo.module.exports();

  // Sign a message using the private key
  const message = 'Hello, world!';
  const signer = new jsrsasign.KJUR.crypto.Signer('SHA256withRSA');
  signer.init(privateKey);
  signer.updateString(message);
  signer.final();

  // Get the signed message and the signature
  const signature = signer.getSignature();
  const signedMessage = signer.toASN1Structure().toDER().getBytes();

  // Print the results
  console.log('Message:', message);
  console.log('Public Key:', publicKey.toPEM());
  console.log('Private Key:', privateKey.toPEM());
  console.log('Signed Message:', signedMessage.toString('base64'));
  console.log('Signature:', signature.toDER().getBytes().toString('base64'));
};
