βš™οΈ Features & Options

Listed below are all the features of Hydra:

Feature Description .Net Framework .Net Core
πŸ”„ Renamer Obfuscates the original assembly by renaming Methods, Properties, Events, Classes, Fields, Namespaces and even the Module of the assembly. Supports exclusion via HydraNoObfuscate attribute. βœ… βœ…

🚧 Under Construction. 🚧

πŸ”„ Renamer - HydraNoObfuscate Attribute

The Renamer feature now supports excluding specific classes and methods from obfuscation using the HydraNoObfuscate attribute.

Usage Example:

// 1. Define the attribute in your code
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method | AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Event)]
public class HydraNoObfuscateAttribute : Attribute
{
}

// 2. Apply to classes you want to exclude completely
[HydraNoObfuscate]
public class ImportantAPIClass
{
    // All members of this class will be excluded from renaming
    public void PublicMethod() { }
    public string PublicProperty { get; set; }
    public string PublicField;
}

// 3. Apply to specific members you want to exclude
public class MyClass
{
    [HydraNoObfuscate]
    public void DoNotRenameThisMethod() 
    {
        // This method will keep its original name
    }
    
    public void ThisMethodWillBeRenamed() 
    {
        // This method will be renamed normally
    }
    
    [HydraNoObfuscate]
    public string ImportantProperty { get; set; }
    
    [HydraNoObfuscate]
    public string criticalField;
    
    [HydraNoObfuscate]
    public event EventHandler ImportantEvent;
}

Key Features:

  • Hierarchical Protection: If a class has [HydraNoObfuscate], all its members are automatically protected
  • Granular Control: Apply the attribute to specific methods, properties, fields, or events
  • Flexible Naming: The attribute works with both HydraNoObfuscate and HydraNoObfuscateAttribute names
  • Zero Configuration: Just add the attribute definition to your code and start using it
