I discovered various reverse thinking methods for cracking JavaScript encryption. all of you have a good method to follow.
A Code , Encrypted around 5 layers, I will crack the last step, and do not need JavaScript decryption Program

List of software used
1. Direct browsing of thunder (download web page) will be executed, but it will not be visible Source code
2. You can use the Firefox software to directly browse the website. Because of the special nature of Firefox, we recommend that you use this browser.
1. Target website http://www.e9ad.cn/pcdd/80-806.htm
We can use thunder to download this page or use the Firefox browser to browse the following code: Copy code The Code is as follows: <script language = JavaScript> var dfqc = function (a) {return string. fromcharcode

What about the decryption?
Let's take a look at document. Write (dfqc (42) + dfqc (126 ).....
In this dfqc (42), dfqc decrypts var dfqc = function (a) {return string. fromcharcode (a ^ 22 )}
I have also thought about the decryption code below. This method can basically crack a lot of similar code. You can refer to this code.<P>
