Android上使用AES加密和解密字符串

废话少说，直接上类的源码

import android.util.Base64;
import java.nio.charset.StandardCharsets;
import java.util.Objects;
import java.util.Random;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import javax.crypto.spec.IvParameterSpec;

public class Encrypt {
   
   

    private static final String CBC_PKCS5_PADDING = "AES/CBC/PKCS5Padding";
    private static final String AES = "AES";
    private static String IvParameter = "";
    private static String key = "";

    public static String encrypt(String data) {
   
   
        return encryptString(data);
    }

    public static String encrypt(int data) {
   
   
        return encryptString(Integer.toString(data));
    }

    public static String encrypt(Long data) {
   
   
        return encryptString(data.toString())
