Security Overview

Stop worrying about passwords that can be cracked in seconds. VBA Padlock provides a professional-grade security architecture that protects your source code by physically removing it from your Office document and executing it within a secure, compiled environment.

The Gold Standard: True Compilation

Section titled “The Gold Standard: True Compilation”

Unlike “VBA Obfuscators” that merely scramble your text, VBA Padlock performs a one-way compilation of your source logic.

Source Code Destruction

During the build process, your original VBA source code is completely eliminated. It is converted into a proprietary bytecode format that exists only within the satellite DLL. Even the most advanced reverse-engineering tools cannot reconstruct your original code.

Our defense-in-depth strategy ensures that your application is protected from every angle.

Secure Execution

Section titled “Secure Execution”

Your compiled logic is executed by a proprietary Virtual Machine (VM) embedded in the runtime.

  • No Readable Text: There are no string literals or logic flows visible to the naked eye.
  • Sandboxed: The VM is optimized for secure macro execution without exposing host vulnerabilities.
