EXECryptor
$125 - SoftComplete Development

EXECryptor is a software protection system for protect programs from reverse engineering, analysis, modifications and cracking. EXECryptor has powerful anticrack, antidebug, antitrace and import code protection features for stop the latest cracking software. and crackers issues. EXECryptor allows to turn program into trial, demo or evalutaion versions and vice versa. You can set flexible number of days or runs of use or limit features of application. These restrictions can be easily changed or combined EXECryptor contains flexible registration and license management system providing application with short serial numbers (12-16 characters). A serial number can be time-limited, may be locked to Hardware ID, can contain encrypted registration information such as license type, allowed features and other user defined information. It supports black list database of 'stolen' illegal keys. EXECryptor uses cryptographically strong serial number generation algorithm that compmletely prevents illegal creation of keygen. EXECryptor supplies you with one-touch trial technology that allows to turn your full-feature application in 'try-before-you-buy' version in a few moments without changing of program code and with serial number registration funtion. EXECryptor has full-feature API to integrate (API interception) in your sprogram. That allows you to create your own unique custom protection for software products. In addition to protection features EXECryptor allows you to compress the code and resources of your application. With EXECryptor compression is not necessary for protect your software. EXECryptor protects not only EXE-files but also DLL and ActiveX components EXECryptor suplies you with command line support allowing to integrate protection in IDE you use. EXECryptor is able to protect software written in Delphi, C++Builder, Microsoft Visual C++, LCC, PellesC, Visual Basic, PowerBASIC, IBASIC, PureBasic. All SDK's and samples are available.

Freeware .NET Obfuscator Skater Light
$0 - RustemSoft

RustemSoft presents Freeware Light Edition of well-known Skater .NET Obfuscator, an obfuscation tool for .NET code protection. The Light Edition is the Free version of Skater .NET Obfuscator. You may use Skater .NET Obfuscator Light Edition, free of charge, to protect your .NET applications for both personal and commercial purposes.
Obfuscation prevents .NET assembly source code recompilation without changing its functionality. Obfuscation deals by hooding the main points of your .NET code.
You need to obfuscate your .NET code because IL (.NET Intermediate Language) code contains all of the information, apart from comments, that is in .NET executable (*.exe or *.dll) files. Using a decompiler a belligerent competitor can easily reverse engineer your .NET apps. To resist this threat, it is possible to obfuscate your assemblies before distributing your software.
The obfuscation process bereaves all unnecessary information used by debuggers from your .NET classes. Also, class, interface, field and method identifiers are renamed to make them meaningless.
By using Skater .NET Obfuscator the obfuscation cannot be reversed.
Skater .NET Obfuscator has dual representation as a GUI interface and as a command-line tool as well. Skater .NET Obfuscator is designed to be seamlessly integrated into your build process that is why it has the command-line interface. This is done in the reliable and repeatable fashion when the obfuscation tool depends on a graphical user interface for operation.
Main features of Skater .NET Obfuscator:
Prohibits reverse engineering;
Obfuscated application usually is not recompilable;
Processes any .NET application, executable or assembly;
Encrypts string constants;
Compatible with any .NET framework (1.x and 2.x);
Control flow obfuscation stops decompilers and deobfuscators;
Scrambles class names, method names, field names etc.;
Implements assemblies linkage; linker unites .NET assemblies into a single dll or exe

.NET Reactor
$169 - EZIRIZ

.NET Reactor is a powerful code protection and software licensing system for software written for the .NET Framework, and supports all languages that generate. .NET Reactor prevents decompilation by a variety of methods which convert your .NET assemblies into processes which no existing tool can decompile ( and which are also very likely to prevent decompilation by any future tool). .NET Reactor builds a native code wall between potential hackers and your .NET assemblies by producing a file which cannot be understood directly as CIL. Because the CIL in your assembly is emitted intact only at run time or design time (in a form in which the source is completely inaccessible), no tool is capable of decompiling .NET Reactor protected assemblies.

The native code wall created by .NET Reactor between the hacker and your source includes industry leading NecroBit technology, which is exclusive to .NET Reactor. .NET Reactor's protection has never been broken since the first release in 2004. These technologies make reconstruction of your source code more difficult by so many orders of magnitude that NecroBit is by far the most effective protection you can use for .NET assemblies.

In addition to industry leading intellectual property protection, .NET Reactor provides powerful options for securing you revenue stream by enforcing licensing terms with a rich variety of trialversion and full version locks.
.NET Reactor offers you an easy and reliable way to:

- Secure your .NET applications and .NET libraries
- Replace CIL code with native code
- Perform additional layers of protection, including obfuscation
- Merge assemblies, and
- Protect your revenue by enforcing trial version restrictions and full version licensing terms.

Spices.Fortress
$292.95 - 9Rays.Net

Distributing and promoting commercial applications as trial and evaluation versions is highly important for any serious developer. However, the process of delivering trial and full versions of the program may be somewhat problematic. If the measures taken to limit the functionality of the full version are not serious enough, it can make way for unauthorized access and illegal use of your program.

You might be searching for an easy way to restrict the functionality of your C# 2.0 Windows Forms application and to create reliably protected demo and trial versions. If so, look no further. Spices.Fortress: an excellent tool that will become the sentinel of your trial functionality and provide your valid customers with an easy way to unlock the application to gain access to all of its functions!

Spices.Fortress has the following distinct advantages:

- protection of .NET applications, but not their obfuscation

- protection of the data needed to run the application, not the code itself

- use of native (but characteristic of C#) means only

- the protected executable is natively compiled by C# (hence no compatibility problems)

- no external processing of C#-produced protected executables

- the Key is not checked but is used to restore the protected functionality

- each Key contains personal data, therefore each Key may be easily identified and verified

The fundamental difference between Spices.Fortress and conventional code protection tools is that it protects only the data needed to run the application, but not the code itself. This goal is reached by using different sets of event handlers for trial and full versions of the same application. Once protected by Spices.Fortress, applications select the necessary set based on the presence of a valid Fortress Key legally obtained from the developers along with a license.

Try Spices.Fortress in action and rest assured that not a single bit of your protected C# 2.0 application will be compromised.

dotNet Protector
$430 - PV Logiciels

dotNet Protector is a powerful .NET code protection system that prevents your assemblies from being decompiled. With dotNet Protector, your application is not simply obfuscated, but method bodies are encrypted. EXE DLL, ASPNET and SQL assemblies can be protected. You can protect a whole application (main exe, referenced dlls) in a single executable. Your .NET code will run entirely from memory, without temporary disk storage.

Protection can be done interactively with an intuitive graphical interface, or automated, using the command-line functionalities of dotNet Protector.

dotNet Protector includes a powerful hardware sensitive anti-piracy system and extensions to help you develop your own software activation system. dotNet Protector is self-protected and uses its internal software activation system.
