There's a bit of code I want to encrypt from users when they use view page source or in inspect element so I want to obfuscate it. (The code is a Javascript)

The one that starts with:

eval( function( p, a, c, k, e, d ) ...

But when I try to put that code in a single post page in the html tab, it shows nothing in the preview tab. Why is that? Or sometimes it shows the code itself.

You can't hide or encrypt nor obfuscate js but you can use a javascript minifier.

Minification refers to the process of removing unnecessary or redundant data without affecting how the resource is processed by the browser - e.g. code comments and formatting, removing unused code, using shorter variable and function names, and so on.

You can use https://www.minifier.org/ to minify on the go.

This minifier removes whitespace, strips comments, combines files, and optimizes/shortens a few common programming patterns.

  • Then why when I inpect some website I see this code that starts with eval(function(p,a,c,k,e,d)... when I deobfuscate it turn out to be a normal JS. – user3279936 Jan 04 '21 at 19:45

Make sure to look at the options and see how it should be obfuscated

  • This is just a fancy minifier. Who does the opposite of minifying. It's just converting to ASCII characters. – amarinediary Jan 05 '21 at 00:45
  • I think, it is what he needs. So with a little tweaking he could get `eval(function(p,a,c,k,e,d)` That he want. the site you refer to is too simple for his need. And all minifier is more or less obfuscate dont you think :) its just simple count on how advanced the tool is. – Alen.Toma Jan 05 '21 at 00:48
  • I agree. But at the end of the day, you can't really hide your code. It's not an intended behaviour, and it shouldn't be encouraged. – amarinediary Jan 05 '21 at 00:50
  • Oh Why is that, its just your opinion. If i develop a tool and want people to buy should I make it simpler for them to use for free. All my hard work etc. I develop some library and I did make them with MIT License but that dose not make it the only right way. Well its as i said, its optional – Alen.Toma Jan 05 '21 at 00:55
  • Sure it's an opinion. But for protecting your intellectual property you have patent, legal defences... etc. In any case, let's not debate. this is just a comment section =D – amarinediary Jan 05 '21 at 00:58
