如何在node.js中使用node-rsa加密数据，在android中如何解密加密数据？

const NodeRSA = require('node-rsa');
const key = new NodeRSA({ b: 512 }); // 选择合适的密钥长度
const publicKey = key.exportKey('public');
const privateKey = key.exportKey('private');

const encryptedData = key.encrypt('要加密的数据', 'base64');

import java.security.KeyFactory;
import java.security.PrivateKey;
import java.security.spec.PKCS8EncodedKeySpec;
import javax.crypto.Cipher;
import android.util.Base64;

public class RSAUtils {
    private static final String PRIVATE_KEY = "这里填写你的私钥";

    public static String decryptData(String encryptedData) {
        try {
            byte[] privateKeyBytes = Base64.decode(PRIVATE_KEY, Base64.DEFAULT);
            PKCS8EncodedKeySpec keySpec = new PKCS8EncodedKeySpec(privateKeyBytes);
            KeyFactory keyFactory = KeyFactory.getInstance("RSA");
            PrivateKey privateKey = keyFactory.generatePrivate(keySpec);

            Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding");
            cipher.init(Cipher.DECRYPT_MODE, privateKey);

            byte[] encryptedBytes = Base64.decode(encryptedData, Base64.DEFAULT);
            byte[] decryptedBytes = cipher.doFinal(encryptedBytes);

            return new String(decryptedBytes);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}
