EasySocket 是一个用于 Android 平台的 Socket 库,它简化了 Socket 通信的实现。要在 EasySocket 中进行数据解密,你需要在接收数据后进行解密操作。以下是一个简单的示例,展示了如何在 EasySocket 中进行数据解密:
dependencies {
implementation 'com.google.crypto:crypto-js:4.1.1'
}
import com.google.crypto.Cipher;
import com.google.crypto.KeyGenerator;
import com.google.crypto.SecretKey;
import com.google.crypto.spec.IvParameterSpec;
import com.google.crypto.spec.SecretKeySpec;
import java.nio.charset.StandardCharsets;
import java.util.Base64;
public class DecryptUtil {
private static SecretKey secretKey;
private static IvParameterSpec ivParameterSpec;
static {
try {
KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
keyGenerator.init(128);
secretKey = keyGenerator.generateKey();
ivParameterSpec = new IvParameterSpec("your_iv_string_here".getBytes(StandardCharsets.UTF_8));
} catch (Exception e) {
e.printStackTrace();
}
}
public static String decrypt(String encryptedData) throws Exception {
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
cipher.init(Cipher.DECRYPT_MODE, secretKey, ivParameterSpec);
byte[] decodedData = Base64.getDecoder().decode(encryptedData);
byte[] decryptedData = cipher.doFinal(decodedData);
return new String(decryptedData, StandardCharsets.UTF_8);
}
}
import com.liyu.easysocketlib.EasySocket;
public class MySocketListener implements EasySocket.OnMessageReceived {
@Override
public void onMessageReceived(String message, EasySocket easySocket) {
try {
String decryptedMessage = DecryptUtil.decrypt(message);
// 处理解密后的数据
} catch (Exception e) {
e.printStackTrace();
}
}
}
现在,当 EasySocket 接收到加密数据时,它将在 onMessageReceived 方法中进行解密。请注意,这个示例仅用于演示目的,实际应用中可能需要根据你的需求进行调整。
