Metadata Obfuscation
DotFix NiceProtect introduces a revolutionary approach to software security: Metadata and RTTI Obfuscation. Unlike standard executable packers that only compress the outer shell of your file, our engine deeply analyzes and sanitizes the internal structures of your compiled application.
The Problem: "Naked" Compiled Code
When you compile applications in Delphi, Free Pascal (Lazarus), or Visual Basic 6.0, the compiler embeds a massive amount of metadata (RTTI - Run-Time Type Information) into the final executable. This includes:- Class Names: e.g., `TMainForm`, `TLicenseChecker`.
- Event Handlers: e.g., `ButtonRegisterClick`, `CheckSerialOnClick`.
- Control Names: e.g., `EditPassword`, `btnUnlock`.
- Public Methods: e.g., `IsValidKey`, `DecryptData`.
Security Risk: A reverse engineer opening your application in a decompiler sees this map immediately. They don't need to understand Assembly language; they simply search for "Registration" or "Password" and find the exact location of your protection logic in seconds.
The Solution: Deep Symbol Renaming
DotFix NiceProtect leverages 20+ years of experience in decompiler development to do the reverse: permanently erase these semantic clues.
Our obfuscation engine parses the binary structure, builds a dependency graph of all objects, and renames them to meaningless, random strings.
Before Obfuscation:
`frmLicense`, `txtPassword`, `btnCheckKey`
After DotFix Obfuscation:
`XF92a`, `zQ12`, `L_0f2`
The logic remains identical, but the context is destroyed. An attacker looking for "AuthForm" will find nothing.
Supported Technologies
Our unique engine supports deep obfuscation for:
- Borland / Embarcadero Delphi: From Delphi 3 up to the latest Delphi 12 Athens (including all XE versions).
- Free Pascal: Applications compiled with Lazarus IDE.
- Visual Basic: Native Code applications built with VB 5.0 and 6.0.
Why This Matters for Security
Many protectors claim to "obfuscate" code but only apply Control Flow Flattening (jumping around in code). While useful, it leaves the map of your application (RTTI) intact. DotFix NiceProtect is one solutions on the market that combines Code Mutation with Metadata Stripping, offering a complete defense-in-depth strategy.
Important: Due to the aggressive nature of this renaming, certain coding patterns (like finding a form by its string name) may need adjustment. Please review the Obfuscation Restrictions guide before enabling this feature.
