.NET Virtualizer.

🎈 ILVirtualization

.NET Virtualizer Made By CursedLand.

🎀 What does this do

This convert .NET ByteCode (aka CIL) into New Set Of Instructions Which Only Understandable By ILVirtualization Runtime.

🎲 Known Clues

• Some Handlers Have Simple Mistakes. (i.e Ldelem_R8, Call, Callvirt, Newobj).
• No Support For Pointer CilOpCodes. (i.e Ldelema, Ldsflda, Ldloca).
• No Support For Exception Handlers.
• Not All Handlers well Tested.
• This Also May Lead to a Noticeable Performance Hit(s).
• Xor is Weak Algorithm.

🧩 What This Made For ?

• Protecting Very Important And Sensitive Codes. (i.e License Checking Code, API Connections).
• Protecting Code That Implements Algorithms.
