kmsAdaptor.encryptDataAndReturn(<plaintext>).then((encryptedData) => {
  console.log('Encrypted Data:', encryptedData);
}).catch((error) => {
  console.error('Encryption Error:', error.message);
});

Decrypt Data

const encryptedData = '<Base64-encoded encrypted data>';
kmsAdaptor.decryptData(encryptedData).then((decryptedData) => {
  console.log('Decrypted Data:', decryptedData);
}).catch((error) => {
  console.error('Decryption Error:', error.message);
});

Configuration

• AWS Key ARN: The kms_key_Arn parameter specifies the KMS key used for encryption and decryption.
