How to make Premium Web Template Free | Decryption of JavaScript In Blogger Theme

I have uploaded a post How To Fix Sora Auto Redirect Problem And Template Footer (Working) 4-5 month ago but some guys have problem bit different about code encryption.

Particularly, Blogger themes have encrypted JavaScript inside and then they ask how to remove that. So, read this complete post to know how to remove/unpack the JavaScript from these themes.

What is Encrypted JavaScript?

Encrypted JavaScript is used to encrypt some lines of the JavaScript code on the web-page particularly the JavaScript which is used for keeping the credit of the theme(credit gives them a back-link). So if you have purchased the theme then there's no problem. If you removed the script directly then your theme starts to misbehave(some sections of the theme may not appear).

In this post, I'll not only tell you how to remove that credit removing script, but will also tell you how to unpack/decrypt those scripts.

Types Of Scripts

There are typically 2 types of scripts we faced in the Blogger templates that are either encrypted or packed . If you can't see any direct executable JavaScript code and want to modify the code, it becomes much difficult. I've 2 tools to help you to decrypt or unpack those script.

But first of all, we need to have a look at those scripts so that you can distinguish them and use the tool.

1.Packed Scripts

You must have seen the following type of scripts in the Blogger template.

eval(function(p,a,c,k,e,r){e=String;if(!''.replace(/^/,String)){while(c--)r[c]=k[c]||c;k=[function(e){return r[e]}];e=function(){return'\\w+'};c=1};while(c--)if(k[c])p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c]);return p}('(0(){4 1="5 6 7 8";0 2(3){9(3)}2(1)})();',10,10,'function|b|something|a|var|some|sample|packed|code|alert'.split('|'),0,{}))

its start from function(p,a,c,k,e,d)... and so on.

Steps to unpack this type of packed javascript are-

1. Copy the whole function starting from eval() to the end of the code.
2. Go to Javascript unpacker or Download Mallzila by bobby and paste that code into the box and click 'unpack'.(in Malzila paste code in decode tab)
3. After successfully unpacked, Copy the code in Output and replace that with the main code.

Note: You may take a backup of the theme before replacing the code as if you got mixed up, then you can restore it back.

2.Encrypted Scripts

Encrypted scripts look something lime below and are defined as the object in a variable.

var _0x760d=["\x64\x69\x73\x70\x6C\x61\x79","\x69\x6E\x6C\x69\x6E\x65\x2D\x62\x6C\x6F\x63\x6B","\x63\x73\x73","\x23\x6D\x73\x63\x6F\x6E\x74\x65\x6E\x74","\x43\x72\x65\x61\x74\x65\x64\x20\x62\x79\x20\x3C\x61\x20\x68\x72\x65\x66\x3D\x22\x68\x74\x74\x70\x3A\x2F\x2F\x77\x77\x77\x2E\x6D\x73\x64\x65\x73\x69\x67\x6E\x62\x64\x2E\x63\x6F\x6D\x22\x3E\x4D\x53\x20\x44\x65\x73\x69\x67\x6E\x3C\x2F\x61\x3E","\x68\x74\x6D\x6C","\x6C\x65\x6E\x67\x74\x68","\x23\x6D\x73\x63\x6F\x6E\x74\x65\x6E\x74\x3A\x76\x69\x73\x69\x62\x6C\x65","\x68\x72\x65\x66","\x6C\x6F\x63\x61\x74\x69\x6F\x6E","\x68\x74\x74\x70\x3A\x2F\x2F\x77\x77\x77\x2E\x6D\x73\x64\x65\x73\x69\x67\x6E\x62\x64\x2E\x63\x6F\x6D","\x72\x65\x61\x64\x79"];

Steps for decrypting this type of the text is below. Sometimes this encrypted Javascript is inside the function(p,a,c,k,e,d). That means we need to unpack the scripts to decrypt this type of scripts.

1. Copy the code between '=' and ';' {equal to and semicolon}.
2. Open JS decrypter Paste the code into the first textbox
3. Click on decrypt.
4. After successfully decryption, Copy the code in Output and replace that with the main code.

After decrypting, the above code will look something like this below

display,inline-block,css,#mscontent,Created by <a href="http://www.msdesignbd.com">MS Design</a>,html,length,#mscontent:visible,href,location,http://www.msdesignbd.com,ready

Screenshot of the script decrypted in JS decrypter.

Tools Used

1. Javascript Unpacker (to unpack the JavaScript)
2. Javascript Decrypter (to decrypt the encrypted JavaScript)

First I'm going to search for eval.

After selecting and copying that code, unpack that(see the picture below.).

Okay after unpack the code you can see the encrypted script there.Its noting but the simple text when decrypted.(Click on Images to open).

Copy and paste it into JS Decrypter.

Finally, replace the decrypted text and Unpacked text with the original once!
