NET Work? ObfuscateAssemblyAttribute System. Why does it happen? Swap with EditorBrowsable attribute Solution 3.There are several ways to protect and obfuscate your. NET code against reverse-engineering. The features at a glance:. When we develop a program, we often present the most valuable information in form of symbol names: names of functions, variables, classes.
This information is precious to an intruder who wants to get an understanding of our software. The simplest and the most effective approach to conceal this information is to make the names irrelevant to what happens inside the program.
Other thing that discloses the information about how a program functions is strings. To hide this information, Eazfuscator. NET substitutes the strings in your code with calls of special encryption functions, which render your strings perfectly at runtime, leaving them unreadable to an intruder. Also, these functions make the size of your strings lesser by compressing them.
There are situations when we want to protect a part of our program more than anything else. We think of a person who would inspect our code as of well-motivated and of one who would go for a desperate measures. In this case, the symbols and strings protection is just not enough. Here we offer you a radical approach: to change the way your program is presented in memory and on disk. Our code virtualization technology translates your.
NET byte code to a randomly generated unrecognizable byte sequence, which still perfectly functions at runtime. In other words, each time you obfuscate your program, we generate a new custom virtual machine to work for you.
NET is the world's first commercial obfuscator that started employing the practical elements of homomorphic encryption. Working in conjunction with code and data virtualization, homomorphic encryption is automatically applied to suitable circuits in your program, making them totally intangible to an attacker. Many of us have dreamt of being able to know every performance-sensitive aspect of the platforms and programming languages we use.
This way, we would always be careful to write only the fastest code. Still, not many of us are actually aware of all the performance-related details, which often change while the platform evolves.
With Eazfuscator. NETyou don't need to be a. NET performance expert to make the top-performing applications. We perform code optimization for you automatically. If your product is ambitious enough, it includes many valuable assets.
I used Eazfuscator to "protect" my VS project - this means Eazfuscator added a post-build event to my project that looks like this:.
This check is probably done so that Eazfuscator does not obfuscate assemblies used for debugging where you may need the pdb files to step through your code, etc.
With Eazfuscator. NET v3 there are improvements made so that you can enable debugging obfuscated assemblies. NET does the check for Release configuration because this is the most common usage scenario. Most developers do builds in Release when they want to do a release.
Of course you are free to use any configuration name whichever you prefer, just update the post-build event as suggested by Rami A. Learn more. Asked 8 years, 10 months ago.
