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
