RikaSDK Documentation

Welcome to the official documentation for the Rika .NET Obfuscator SDK. Using the attributes defined in the RikaSDK namespace, you can fine-tune the protection process directly from your source code.

Installation

Simply add the provided SDK file to your project solution.

C# Projects

Add RikaSDK.cs to your project root.

Project Root/
├── Program.cs
└── RikaSDK.cs

VB.NET Projects

Add RikaSDK.vb to your project root.

Enum Enumerations

RenameType

Defines available character sets for renaming.

Value	Description
Japanese	Kanji/Kana characters.
Chinese	Chinese characters.
Tibetian	Tibetan script characters.
Guid	Unique GUIDs (e.g., c234-54...).

MemberType

Specifies the type of members to target.

Classes Methods Fields Params Events Properties

VirtualizationMode

Defines the complexity level of the VM generation.

Value	Description	Complexity
Normal	Balanced protection. Recommended for general logic.	Medium
Ultra	Maximum protection. Slightly higher performance cost.	High

Attr Assembly Attributes

RenamingType

Single Instance

Sets the global renaming mode for the entire assembly.

[assembly: RenamingType(RenameType.Japanese)]

ExcludeMemberFromRenaming

AllowMultiple

Specifies member types to be excluded from renaming globally.

[assembly: ExcludeMemberFromRenaming(MemberType.Properties)]
[assembly: ExcludeMemberFromRenaming(MemberType.Events)]

DisableIntegrityProtection

Disables runtime anti-tamper checks. Useful for self-signing or debugging.

[assembly: DisableIntegrityProtection]

Attr Member Attributes

EnableVirtualization

Converts standard MSIL instructions into a proprietary bytecode format interpreted by a custom VM.

Performance Warning: Avoid using VirtualizationMode.Ultra on methods called inside tight loops (e.g., rendering loops or rigorous math calculations). For high-frequency methods, use Normal or exclude them.

[EnableVirtualization(VirtualizationMode.Ultra)]
public bool ValidateLicense(string key) { ... }

DisableStringEncryption

Disables string encryption for the target member. Use on hot-paths for performance.

[DisableStringEncryption]
public void LogDebug(string msg) { ... }

DisableReferenceProxy

Disables proxying for external method calls. By default, Rika hides external calls (e.g., MessageBox.Show) behind internal proxies to prevent static analysis.

[DisableReferenceProxy]
public void CallNativeApi() { ... }

DisableControlFlow

Prevents control flow flattening (spaghetti code). Use this if obfuscation breaks a specific method's logic or causes excessive slowdowns.

[DisableControlFlow]
public int CalculatePhysics() { ... }

DisableRenaming

Complete Exclusion: Prevents renaming of the type itself AND all its members (fields, methods, props). Essential for Serialization, Reflection, or Public APIs.

[DisableRenaming]
public class UserSettings { // Not Renamed
    public string Username { get; set; } // Not Renamed
}

DisableRenamingTypeName

Partial Exclusion: Preserves the Class/Struct name but allows renaming of its members. Useful for plugins where the class name is looked up by string, but internal logic should remain hidden.

[DisableRenamingTypeName]
public class MyPluginEntry { // Not Renamed
    private void SecretLogic() { ... } // Renamed
}
