Getting cardEncrypted from webpay

Hello,
I have been trying to get the cardEncrypted in android java

public static PublicKey getPublicKey(final BigInteger modulus, final BigInteger exponent) {
  try {
    final KeyFactory factory = KeyFactory.getInstance("RSA");
    final PublicKey publicKey = factory.generatePublic(new RSAPublicKeySpec(modulus, exponent));
    return publicKey;
  } catch (GeneralSecurityException e) {
    return null;
  }
}


public static String encryptPAN(final String prefix, final String pan, PublicKey publicKey) {
  byte[] input = String.format("%s%s", prefix, pan).getBytes();


  try {
    Cipher cipher = Cipher.getInstance("RSA/None/OAEPWithSHA1AndMGF1Padding");
    cipher.init(Cipher.ENCRYPT_MODE, publicKey, new SecureRandom());
    byte[] cipherText = cipher.doFinal(input);
    return Base64.encodeToString(cipherText, Base64.DEFAULT);
  } catch (GeneralSecurityException ignore) {
    return null;
  }
}

here is the code

Please take a look at our Java example implementation from this repo.

Let me know if you can get it working. Make sure project SDK, language level and JRE are set to Java 8.

Also, since you're developing an Android app, you can use the Clover Android SDK. Here's our documentation on it: https://docs.clover.com/clover-platform/docs/using-payment-connector
