Why Xerin?

Affordable price

Production-grade protection at a price that stays accessible for solo developers and teams.

Optimized obfuscation

Protection passes are tuned to keep output stable, fast, and practical for real applications.

Complex algorithms

Layered transformations make decompiled output harder to inspect, trace, and rebuild.

Comprehensive .NET Support

Built for modern .NET targets with support for common desktop, server, and app workflows.

Easy to Use

A straightforward workflow lets you protect builds without fighting complex configuration.

Merge DLLs

Bundle dependencies into cleaner protected outputs for easier delivery and deployment.

Advanced Obfuscation Techniques

Runtime

Code virtualization

Transforms code into a virtual machine format that's harder to reverse engineer

Control flow

Mangles and restructures IL code to make it extremely difficult to understand program logic after decompilation

Code mutation

Transforms IL instructions into equivalent but more complex sequences, making code analysis extremely difficult while maintaining identical runtime behavior

Delegate Reference Proxy

Creates proxy methods for target functions with parameter forwarding and original function invocation through Reflection/Delegates. Proxies can modify signatures, add encryption layers, or resolve functions dynamically at runtime via encrypted delegate tables

Integrity Check

Compares MD5 hash of the assembly at runtime to detect unauthorized modifications or tampering. Automatically terminates execution if integrity verification fails, protecting against code injection and reverse engineering attempts

VM

Code virtualization

Converts original IL instructions into custom bytecode executed by a built-in virtual machine interpreter, making decompilation nearly impossible as tools only see the VM interpreter instead of actual code

Code encryption

Encrypts code segments and decrypts at runtime for maximum protection

Control flow

Restructures IL code by reordering and reorganizing internal code structure, making program logic extremely difficult to understand after decompilation while maintaining functionality

Code mutation

Transforms IL instructions by replacing simple operations with complex equivalent sequences, converting constants to encrypted forms, and injecting junk code while maintaining identical runtime behavior

Symbols renaming

Renames all types, methods, properties, fields, and parameters to unreadable names using alphabet or unprintable Unicode characters

String encryption

Encrypts strings using advanced algorithms with compression and caching for optimal performance

123

Integer encryption

Protects integer values with optimized XOR-based encryption algorithms

Anti-Decompiling

Prevents source code decompilation with advanced protection layers

Anti-Debugging

Detects and blocks debugging tools like x64dbg also detecting scylla hide to prevent runtime analysis

Anti-Dumping

Prevents memory extraction and dumping of protected assemblies

HTTP

Anti-Http Debug

Prevents HTTP debugging attempts on your assembly

Resources Encryption

Encrypts all embedded resources within the assembly and applies compression to reduce file size significantly

Imports Protection

Secures and conceals all WinAPI imports and general imports

A B C 0 1 2

Enum Protection

Removes enums and replaces references with underlying values

C

Constants Mover

Converts constants to objects, proxies them, then restores on use

P

Delegate Reference Proxy

Creates proxy methods for target functions with parameter forwarding and original function invocation through Reflection/Delegates. Proxies can modify signatures, add encryption layers, or resolve functions dynamically at runtime via encrypted delegate tables

Integrity Check

Compares MD5 hash of the assembly at runtime to detect unauthorized modifications or tampering. Automatically terminates execution if integrity verification fails, protecting against code injection and reverse engineering attempts

Anti Tamper

Monitors runtime execution for tampering attempts including method modifications and dynamic calls from unexpected assemblies. Immediately terminates execution when any unauthorized manipulation is detected to prevent further operations

And Many More...

Discover dozens of additional advanced obfuscation techniques designed to keep your code secure. Each feature is crafted to provide maximum protection while maintaining optimal performance.

Real Protection Output

See the code during protection

Explore real before and after snapshots showing how readable .NET code turns into hardened protected output.

Code Virtualization

Transforms original IL instructions into custom bytecode that runs on a built-in virtual machine interpreter. Instead of executing real code directly, decompilers only see the VM interpreter, making reverse engineering nearly impossible as the actual program logic is hidden within virtualized instructions.

Code Before & After Virtualization
Before Virtualization
private static void Main()
{
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new Form1());
}
After Virtualization
[MethodImpl(MethodImplOptions.NoInlining)]
private static void Main()
{
}

Delegate Reference Proxy

Creates proxy methods for target functions with parameter forwarding and original function invocation through Reflection/Delegates. Proxies can modify signatures, add encryption layers, or resolve functions dynamically at runtime via encrypted delegate tables.

Code Before & After Reference Proxy
Before Proxy
private static void Main()
{
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);
    Application.Run(new Form1());
}
After Proxy
private static void Main()
{
    A04B6290.B8ABFE99()();
    A026CC00.E82426CC()(false);
    BD739D71.F5AC4B73()(B778897A.D895E6A6()());
}

Control Flow Obfuscation

Mangles and restructures IL code by reordering and reorganizing internal code structure, making it extremely difficult to understand program logic after decompilation. The code remains functionally identical but becomes nearly impossible to analyze.
