Restricting other EXE calling my own exe

Question

For the Security purpose, I have to restrict other third party exe calling or opening my exe.

So Far I'm checking the digital signature of the parent, but with PID spoofing, the digital signature check is cracked.

Then I tried sending encrypted argument to the child process, but with debugger anyone can get the password send as argument. So it also cracked.

Finally, I tried named pipes, then made digital signature check for the serer and client PID. Its Working good but for concurrent process its not working properly.

Can you help in this case. to have a secure way to protect my exes.

Hello,

Welcome to Microsoft Q&A!

You can use a key which other EXE must supply to verify your exe content signature with Cryptography API: Next Generation. Using SignHashAndVerifySignature example, You can compute your exe content instead of the static Message.

Thank you.
