Protection,
layer by layer.

A set of complementary protections. Apply the layers your application needs, with control down to individual methods.

String Encryption

Protects sensitive strings with strong algorithms to prevent exposure of keys, passwords, or API tokens.

Code Virtualization

Transforms methods into a unique virtual machine (VM) format.

Anti‑Tamper

Prevents static decompilers from viewing your original code and blocks tampering attempts.

Renaming

Obfuscates classes, methods, and many other identifiers into meaningless names.

Control Flow Obfuscation

Modifies structure to unreadable forms without changing logic.

Resource Encryption

Encrypts embedded resources to prevent direct access by external tools.

Reference Proxy

Replaces direct reference calls with indirect proxy calls.

Anti‑VM

Detects virtualized/sandboxed environments and terminates execution if detected.

Library Mode

Preserves public member names for referenced libraries to avoid breaking functionality.

Your protection.
Your rules.

Use RikaSDK attributes to select methods for virtualization, preserve public interfaces and configure renaming directly in your source code.

About Rika .NET

We built this because we needed it and nothing out there was good enough.

Developed & Hosted Here

Where we work from

We work out of Istanbul, Turkey. Development, hosting, support, it all runs from here.

How it started

We started writing this in November 2024. At first it was just something we put together for our own use. Then it kept growing and we decided to ship it properly.

Why we made it

We went through a lot of .NET obfuscators over the years. Most of them worked fine for a while, then updates stopped and support went quiet. On top of that, deobfuscators for those tools kept popping up, making them pretty much useless. You'd end up searching for alternatives again, finding the same stale options. We got tired of that cycle and wrote our own. Rika .NET is what we wanted to exist from the start.
