Friends of the company developed online JS encryption site, in the internal test, you can not find the encrypted source code, do not know that there is a large enough to crack the http://www.vvorld.cn

The Code is as follows:


Script
Str = "corrected code. Welcome to crack it again ";
// Note: The power of netizens is powerful.
For (I = 1; I <10; I ++ ){
For (j = 1; j <= I; j ++ ){
Str + = I + "*" + j + "=" + I * j + "";
If (I = j) {str + = "\ n "};
}
}
Alert (str );

I don't know how xiaoqin has used it. I used a self-made debugging tool (similar to firedebug). There are countless tools like this, which are hard to prevent.

In fact, there is such a method that does not use professional tools. It is funny, but it is also effective.
1. First, turn on the bandwidth-consuming software such as the electric terminal and thunder to slow down your network speed.
2, then open the test page with a browser: http://www.topsid.cn/user.php? Id = 17
Before loading the page, enter (copy and paste) in the address bar of the browser: copy the content to the clipboard code:
Javascript: function myFlash_DoFSCommand (c, args) {document. write (" "+ Args +"")} If the time is right, you can replace the key functions and let the source code be in its own shape.

There should be a few people who can crack this encryption. I have received a short message and asked the landlord how to crack it, so I will not keep it confidential.
Let's talk about your method later.
