React Native Requires Chilkat v11.0.0+

Use Base64 RSA Key to Encrypt

See more RSA Examples

Loads a Base64 RSA key and uses it to encrypt a string, returning the result in base64. React Native

import { PublicKey, Rsa } from '@chilkat/react-native'

function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const pubkey = new PublicKey();

  try {
    pubkey.loadBase64('MIICdgIBADA ... A9PXLk+j5A==');
  } catch {
    console.log(pubkey.lastErrorText);
    return;
  }

  const rsa = new Rsa();

  try {
    rsa.usePublicKey(pubkey);
  } catch {
    console.log(rsa.lastErrorText);
    return;
  }

  rsa.encodingMode = 'base64';

  const encryptedStr = rsa.encryptStringENC('12345678', false);

  console.log(encryptedStr);
}
