58同城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)
?
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();}}?
很久没写博，上来溜溜，我是firstep
