将18693157906加密后的密文是 FAD42A3BB2A4B9A5B36847714A56FE65

二、java中对应的加密、解密方法

public class Utils {
#密钥	
private static String key = "test#5&124*!de";
 /**
  *      加密
  * @param inStr
  * @return
  */
   public static String ENCRYPT_DES(String inStr)  { 
	   DESKeySpec desKey;
	   SecretKey securekey;
	   Cipher cipher; 
	  try {
		desKey = new DESKeySpec(key.getBytes());
		securekey = SecretKeyFactory.getInstance("DES").generateSecret(desKey);
	    cipher = Cipher.getInstance("DES/CBC/NoPadding");
	    cipher.init(Cipher.ENCRYPT_MODE, securekey, new IvParameterSpec(new byte[8]));
        byte[] inBytes = new byte[((int) (inStr.length() / 8) + 1) * 8];
        for (int i = 0; i < inStr.length(); i++) {
        inBytes[i] = inStr.getBytes()[i];
        }
       byte[] enBytes = cipher.doFinal(inBytes);
       String hexStr = DatatypeConverter.printHexBinary(enBytes);
       return hexStr;
	} catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
	return null;
   }
   /**
    *    解密
    * @param encryptStr
    * @return
    */
   public static  String DECRYPT_DES(String encryptStr)  { 
	   DESKeySpec desKey;
	   SecretKey securekey;
	   Cipher cipher; 
	 try {
		 desKey = new DESKeySpec(key.getBytes());
         securekey = SecretKeyFactory.getInstance("DES").generateSecret(desKey);
	     cipher = Cipher.getInstance("DES/CBC/NoPadding");
	     cipher.init(Cipher.DECRYPT_MODE, securekey, new IvParameterSpec(new byte[8]));
		 byte[] decryptBytes = cipher.doFinal(Hex.decodeHex(encryptStr.toCharArray()));
		 return new String(decryptBytes).trim();
	} catch (Exception e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
	return null;
   }
   public static void main(String[] args) {
	   System.out.println("加密："+ENCRYPT_DES("18693157906"));
	   System.out.println("解密："+DECRYPT_DES("FAD42A3BB2A4B9A5B36847714A56FE65"));
