some questions about VMProtect products

Hello,

I am interested in a company-level license of VMProtect, but I have some questions here.

Case 1, our products might be dll/dcu, can VMProtect protect these files? after protection, can exe or dll call the functions in protected dll?

Case 2, is there any SDK of VMProtect? I mean, can we protect our software by API call, not via VMProtect GUI? (passing parameters for sure)

Case 3, if there is no SDK, is there any console mode working? (slient console mode).

Thanks!

VMProtect can protect DLL files but can not protect DCU files. After protection EXE/DLL files can call the functions from protected DLL.

Case 2, is there any SDK of VMProtect? I mean, can we protect our software by API call, not via VMProtect GUI? (passing parameters for sure)

In new version (1.8 ) you can use API calls (markers) from SDK but you must add these markers in project via GIU or via script.

Case 3, if there is no SDK, is there any console mode working? (slient console mode).

VMProtect have GUI and console version (console version work with project files prepared in the GUI version).

Thanks for your quick answers.

I just downloaded VMProtect (demo) for testing. Let me explain my situation here.

We have an EXE file A (this is our product), and we run this EXE file A and input some data, then EXE file A can generate EXE file B, then we send EXE file B to our customers. So it is more like e-book application, that we use EXE file to generate other EXE files.

What I need is to call VMProtect APIs from EXE file A, when EXE file B is generated, EXE file A can use VMProtect APIs to encrypt EXE file B, so that make EXE file B protected. EXE file B can work without any extra VMProtect dll (all the data is packed in EXE file B). is it possible?

So there is no VMProtect GUI involved in final protection process (but we can use VMprotect GUI to generate script). is it possbile?

Sorry for some many questions... hope you have a greate weekend!

If you want to use VMProtect as part of your protection system (on customer side) - it will break the License Agreement.

thanks for your answer.

I think console function is not working in demo version, right?

I am a freelance developer, but I develope software for companies, so what version/level shall I choose? if there is no functions in company license, I think I need company license, right?
