Assembly Lockbox

Categories:
Author: Gibwo
Latest version: 1.0
Description: 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.

Salamander .NET Protector

 Home Page Home Page
Categories:
Author: Remotesoft
Latest version: 1.1.5
Description: Shuts down MSIL disassembly and decompilation rather than simply obfuscating code. It's not an obfuscator, rather it converts the decompilable Microsoft Intermediate Language code (MSIL or CIL) of your assemblies into native format while keeping all .NET metadata intact, and thus it provides the same level of protection as native C/C++ code. Further more, it offers code, string and resource encryption, and therefore, it provides even better protection than native C/C++ code.

DeployLX CodeVeil

 Home Page Home Page
Categories:
Author: Xheo
Latest version: 3.2
Description: 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.
