android客户端手机号码解密方法

由于58同城在页面上抓取二手房信息的时候，用户的联系电话是图片的，本人水平关系无法进行很好的识别，所以转为抓取其android客户端比较容易，之前都是好好的，最近发现其升级到1.3.0.0后手机号码进行了加密，所以直接反编译其android客户端，查到其用的是des加密，而且加密的key很容易就拿到，下面贴出解密方法。(des加解密比较简单下面贴出来)
 
Java代码 
import java.security.SecureRandom; 
import javax.crypto.Cipher; 
import javax.crypto.SecretKey; 
import javax.crypto.SecretKeyFactory; 
import javax.crypto.spec.DESKeySpec; 
 
public class Decode458 { 
    static byte[] key = null; //这个key如果有需要请反编译58客户端获取这里不便贴出 
     
    public static void main(String[] args) throws Exception { 
        System.out.println(new String(Decode458.decode(Decode458.convertHexString("002E674657AE8239982087DCB2E6A99B")))); 
        System.out.println(Decode458.toHexString(Decode458.encode("13219863008".getBytes()))); 
    } 
     
    public static byte[] decode(byte[] paramArrayOfByte) { 
        try { 
            SecureRandom localSecureRandom = new SecureRandom(); 
            DESKeySpec localDESKeySpec = new DESKeySpec(key); 
            SecretKey localSecretKey = SecretKeyFactory.getInstance("DES") 
                    .generateSecret(localDESKeySpec); 
            Cipher localCipher = Cipher.getInstance("DES"); 
            localCipher.init(2, localSecretKey, localSecureRandom); 
            return localCipher.doFinal(paramArrayOfByte); 
        } catch (Exception e) { 
            e.printStackTrace(); 
            return null; 
        } 
    } 
     
    public static byte[] encode(byte[] paramArrayOfByte) { 
        try { 
            SecureRandom localSecureRandom = new SecureRandom();
