Dotfuscator Community Edition with Visual Studio® .NET 2003

Posted: 11 Jul 2007 01:05 AM CDT

With the help of tools like ILDASM (the MSIL disassembler that ships with the .NET Framework SDK) or decompilers such as Anakrino and Reflector for .NET, anyone can easily look at your assemblies and reverse engineer them back into readable source code. Hackers can search for security flaws to exploit, steal unique ideas, and crack programs. This should be enough to give you pause.

However there's a solution—obfuscation—that will help you thwart reverse engineering. Obfuscation is a technique that provides for seamless renaming of symbols in assemblies as well as other tricks to foil decompilers. When it is properly applied, obfuscation can increase the protection against decompilation by many orders of magnitude, while leaving the application intact. Obfuscation is commonly used in Java environments and for years has been helping companies protect the intellectual property in their Java-based products.

Microsoft includes the Dotfuscator Community Edition with Visual Studio® .NET 2003 in partnership with our company PreEmptive Solutions, which ships a number of various obfuscator packages.
