Best .NET obfuscation tools/strategy

My product is both ASP.NET, Windows forms app and Windows service. 95% of code is .NET (VB if you must know). For IP reasons, I need to obfuscate the code. I am using an old dotfuscator (over 5 years old) and thinking it is time to move to a new gen. Anyone can recommend from their personal experience (please don't just give me a list ...

Flex / Air obfuscation

I've written (most of) an application in Flex and I am concerned with protecting the source code. I fired up a demo of Trillix swf decompiler and opened up the swf file that was installed to my Program Files directory. I saw that all of the actionscript packages I wrote were there. I'm not too concerned with the packages, even though the...

Should I be worried about obfuscating my .NET code?

I'm sure many readers on SO have used Lutz Roeder's .NET reflector to decompile their .NET code. I was amazed just how accurately our source code could be recontructed from our compiled assemblies. I'd be interested in hearing how many of you use obfuscation, and for what sort of products? I'm sure that this is a much more important ...

Do you obfuscate your commercial Java code?

I wonder if anyone uses commercial/free java obfuscators on his own commercial product. I know only about one project that actually had an obfuscating step in the ant build step for releases. Do you obfuscate? And if so, why do you obfuscate? Is it really a way to protect the code or is it just a better feeling for the developers/manag...

Is obfuscator Javascript enough?

I'm working on building a development tool that is written in Javascript. This will not be an open source project and will be sold (hopefully) as a commercial product. I'm evaluating the best way to protect my investment. Is using an obfuscator (code mangler) enough to reasonably secure the code? Are there other alternatives that I am...

What should I do if I want to release a .net assembly but wish to keep its internals detailed in the manifest private (from a utility such as ildasm.exe) ? ...

(Why) should I use obfuscation?

It seems to me obfuscation is an idea that falls somewhere in the "security by obscurity" or "false sense of protection" camp. To protect intellectual property, there's copyright; to prevent security issues from being found, there's fixing those issues. In short, I regard it as a technical solution to a social problem. Those almost never...

Does the exe you get out of obfuscation programs vary in speed?

There are a number of obfuscation programs out there for .Net and I've tried one, my exe seems much slower when obfuscated. Do all obfuscation programs have the same effect or have I chosen a bad one? I'm hoping some are better than others, if you know of a fast one let me know. Cheers ...

Is there a good obfuscater for Perl code?

Does anyone know of a good code obsfucator for Perl? I'm being ask to look into the option of obsfucating code before releasing it to a client. I know obsfucated code can still be reverse engineered, but that's not our main concern. Some clients are making small changes to the source code that we give them and it's giving us nightmares...

What's the best value for money c# code protection for a single developer

What's the best value for money c# code protection? Some just use obfuscation, others add win32 wrapping, some cost a fortune. So far I've come up with http://www.eziriz.com/ who's Intellilock looks promising. Any other suggestions? Any reasons why this is not a good idea? I know its impossible to completely protect but I'd prefer the a...

Should you obfuscate a commercial .Net application?

We're releasing a Mac version of our Windows application.

Best Java Obfuscation Application For Size Reduction

An important part of mobile development, especially when you are talking about mobile games, is dealing with the application size restrictions. Some devices enforce their own size limits, while all the carriers have their own size requirements for applications to be released in their deck space. My question is, is there a java obfuscati...

Can you Distribute a Ruby on Rails Application without Source?

I'm wondering if it's possible to distribute a RoR app for production use without source code? I've seen this post on SO, but my situation is a little different. This would be an app administered by people with some clue, so I'm cool with still requiring an Apache/Mongrel/MySQL setup on the customer end. All I really want is for the s...

Obfuscation Puzzle: Can you figure out what this Perl function does?

sub foo {[$#{$_[!$||$|]}*@{$_[!!$_^!$_]}[email protected]{$_[!$..!!$.]}[$_[@[email protected]+]% @{$_[$==~/(?=)//!$`]}..$#{$_[$??!!$?:!$?]},($)?!$):!!$))..$_[$--$-]%@{ $_[$]/$]]}-(!!$++!$+)]:@{$_[!!$^^^!$^^]}]} update: I thought the word "puzzle" would imply this, but: I know what it does - I wrote it. If the puzzle doesn't interest you, please don't waste any ti...

What do you use to protect your .NET code from reverse engineering?

For a while we were using a tool called CodeVeil. I'm just wondering if there are better alternatives out there. Edit: Before more people misunderstand the question, I'm aware that a determined cracker would probably be able to defeat any of these tools. I'm not too concerned about them though. These tools are just meant to stop the...

Code Obfuscation?

So, I have a penchant for Easter Eggs... this dates back to me being part of the found community of the Easter Egg Archive. However, I also do a lot of open source programming. What I want to know is, what do you think is the best way to SYSTEMATICALLY and METHODICALLY obfuscate code. Examples in PHP/Python/C/C++ preferred, but in oth...
