This is a security issue related to deployment.

I would like to ask for a certificate or some verification to install the program in an environment where the internet is not available.

My idea is to create and manage files that can be decrypted.

There's a problem..

For example, if a company named "a" has a certificate or any kind of verification, it would be possible for a company named "b" to certify that it is not possible.

If you give company A ID and PASSWORD corresponding to the certificate, company B wants to prevent ID, PASSWORD corresponding to company A certificate.

Is this possible?

What I have tried:

I created an encrypted and decryptable file by entering id and password.

Take a look at this: Application Trial Maker[^]
If someone decides to buy your application, he calls you and reads his computer ID. Then the Serial Maker can be used to make a serial key (password). After entering the password, the application runs as the full version.

Another option would be to use the built in Licensing classes in .NET: How To: Component Licensing in .NET[^]

Not sure it resolves OP issue. He/She is, probably(!), asking about how to avoid certificate duplicates, but i'm not sure what it means...

At work a colleague already had implemented the licensing, and I was put on other projects. Also even if I knew I would not be allowed to tell you the details I'm afraid. The only thing I know is that it works with a licensing server that checks the licensing code ...
