Assembly Lockbox

Home Page

Categories: Code protection - Obfuscation

Author: Gibwo

Latest version: 1.0
Added 2007-08-23

Encrypts .NET assemblies without modifying the code and without packaging them into a native processor wrapper, which can alert virus scanners.
Assembly Lockbox protects code and decrypts the assemblies at run time. It uses custom lockcores so that each encrypted assembly can have its own unlocking mechanism. This means that no "golden key" can crack all assemblies protected with Assembly Lockbox.

DeployLX CodeVeil

Categories: Code protection - Obfuscation

Author: Xheo

Latest version: 3.2
Added 2005-11-20Updated 2009-01-06

Encrypts .NET applications and DLLs.
CodeVeil adds native code to assemblies to decrypt the assembly just before the .NET runtime needs access to the data.

Features include:
- Full MSIL encryption: your MSIL is encrypted and cannot be read with readers like ILDASM or Reflector.
- Resource and string encryption: strings embedded in your code, and resources like images and form text can now be encrypted.
- Blob encryption: selectively encrypt data stored in the blob heap. This data includes parameters for attributes, default values for fields, and method signature information.
- Encrypt both EXEs and DLLs.
- Obfuscation: obfuscate the names of public classes, methods, properties and fields.
- Anti-debugging, anti-tracing.
- Modification resistence: CodeVeil creates dependencies on the unmodified source so that a user cannot modify your assembly without making it completely unusable.

Author: PV Logiciels

Latest version: 5.3
Added 2005-02-15Updated 2007-10-29

Code protection system that prevents your assemblies from being decompiled.
With dotNet Protector, your application is not simply obfuscated, but method bodies are encrypted also, while keeping its .NET nature.

Features include:
- EXEs, DLLs, ASP.NET and SQL assemblies can be protected.
- Support for v1.1, v2, v3.0, v3.5 frameworks.
- Support for x86, AMD64 and Itanium architectures.
- You can protect a whole application (main EXE, referenced DLLs) in a single executable.
- Protection can be done interactively with a graphical interface, or automated, using the command-line.
- Evaluation Generator: dotNet Protector can generate a limited executable. You can choose executable lifetime (in days): your program wont launch beyond this limit.
- A hardware lock system is integrated with dotNet Protector. Running your program can depend on a valid unlock key.
