Code Virtualizer

What Code Virtualizer is

Code Virtualizer helps developers make selected parts of applications and dynamic libraries harder to reverse engineer. It converts chosen x86, x64, or ARM64 instructions into virtual opcodes that an internal virtual machine interprets. Each protected application receives its own virtual opcodes and virtual machine.

The software works with native PE, ELF, and Mach-O files, including executables, services, DLLs, shared objects, and device drivers. Developers identify code sections for protection with the VIRTUALIZER_START and VIRTUALIZER_END macros in VirtualizerSDK.h. Listed capabilities include multiple virtual machines, an advanced mutation engine, code relocation, and command-line protection. The maker says it is compatible with any compressor or protector.

Code Virtualizer supports Windows, macOS, and Linux. A demo version is available for evaluation, but it cannot be registered and applies only light code virtualization. It also lacks string encryption, mutate macros, and compressed virtual machines, and it adds a demo splash screen. A purchase includes one year of free software updates and technical support by email; the maker says replies usually arrive within 24–48 hours. Plans are available for x86/x64 and ARM64, with separate developer and company licenses.

Who it suits

Code Virtualizer suits developers protecting sensitive code in applications, libraries, and device drivers, including Windows device drivers. Its license options distinguish solo developers or one-developer companies from companies with more than one software developer.

Limits

The demo provides light virtualization, omits string encryption, mutate macros, and compressed virtual machines, and adds a splash screen. A purchase includes one year of free software updates.

Getting started

1. Visit the Code Virtualizer website.
2. Download the demo version to evaluate its light code virtualization, or select a paid license.
3. Choose an x86/x64 or ARM64 license, and select the developer or company option.
4. Integrate the SDK by marking code areas with VIRTUALIZER_START and VIRTUALIZER_END macros from VirtualizerSDK.h.
5. Use Code Virtualizer to protect the selected code in a supported native file.

Verdict

Choose Code Virtualizer when you need to protect selected native code areas across supported file formats and instruction architectures. The demo can help evaluate light virtualization. Check the developer or company license and architecture before purchase, since the listed prices vary by both.
