Questions about how to load content and MD5 After clicking

I have several categories about loading content and MD5 After clicking, that is, displaying content and images after clicking. However, I used display: none to hide the corresponding content and images, that is not to hide, but the content and images have been loaded in advance .. Is there a way to hide the content before loading the corresponding content and image when I click the corresponding category? Another problem is that I use P to load the content and MD5 After clicking.

Another problem is that the result of using the PHP md5 function to encrypt 111111 is 96e79218965eb72c92a549dd5a330112. But is there any way to use PHP to encrypt 111111 to encrypt? This is also MD5.
Thank you for your help.

------ Solution --------------------
Write your own encryption algorithm. The principle is very simple, that is, to convert the string according to certain rules, that is, to encrypt the string, and then convert the converted string in reverse order to restore it.

1. JS delays loading and stores the source address in the original attribute of img.
2,

PHP code

[User: root Time: 11: 14: 10 Path:/home/liangdong/php] $ php md5.php login [User: root Time: 11: 14: 13 Path: /home/liangdong/php] $ cat md5.php
  [User: root Time: 11: 14: 15 Path:/home/liangdong/php] $

Search for 70-66-A4-0F-42-77-69-CC-43-34-7A-A9-6B-72-93-1A
We can see that this is 123456 MD5 instead of 111111 MD5.
Some people say that conversion to unicode encoding and MD5 can be obtained.
But unfortunately, whether it is converted into a UCS-2BE, ucs-2le, ucs-4le, ucs-4be in php can not MD5

Can be used together:
