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();
            DESKeySpec localDESKeySpec = new DESKeySpec(key);
            SecretKey localSecretKey = SecretKeyFactory.getInstance("DES")
                    .generateSecret(localDESKeySpec);
            Cipher localCipher = Cipher.getInstance("DES");
            localCipher.init(1, localSecretKey, localSecureRandom);
            return localCipher.doFinal(paramArrayOfByte);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

    public static byte[] convertHexString(String text) {
        byte digest[] = new byte[text.length() / 2];
        for (int i = 0; i < digest.length; i++) {
            String byteString = text.substring(2 * i, 2 * i + 2);
            int byteValue = Integer.parseInt(byteString, 16);
            digest[i] = (byte) byteValue;
        }
        return digest;
    }

    public static String toHexString(byte b[]) {
        StringBuffer hexString = new StringBuffer();
        for (int i = 0; i < b.length; i++) {
            String plainText = Integer.toHexString(0xff & b[i]);
            if (plainText.length() < 2)
                plainText = "0" + plainText;
            hexString.append(plainText);
        }
        return hexString.toString();
    }
}
