Hi and thanks for all info! The price for a certificate is certainly low. I expected at least two zeros after.
This is actually very fun and learning. After reading the links you supplied and reading my own instructions in the guide I would do this:
1.choose the certificate to buy. After the payment process I assume you must enter the domain name and a password. Since this is for a single domain it can be www.domain.com OR domain.com.
2.certificate is generated and you can pick it up on a server I assume.
3.now you have a file in the PEM format (most likely) with the extension .pem, .crt, .cer, or .key.
4.the web server for NCS running on Windows use the certificate with extension .pfx meaning that the binary file includes both the certificate and the key/password.
5.most likely the certificate you receive do not end with .pfx since they probably use unix machines so it is necessary to convert to .pfx.
6.use the converter in the link above and convert from most likely (the converter finds out that by itself) and convert it to PKCS#12/PFX format.
7.now you have the certificate in the correct format. Now it is time to install it and continue to follow the guide. Double-click on the certificate and let the wizard install the certificate. Follow the guide.
8.finally, move/copy the certificate to C:\Program Files\Netcam Studio - 64-bit and edit the config files.
9.start NCS and use https. The important part is again that the chosen domain name abc.com must be the same as the one in the calling URL meaning that https://abc.com. Then one gets the green text meaning that the name in the certificate is corresponding to the URL.
This should be it. If something goes wrong you have always the certificate in original and can start over. Unfortunately, I don’t have access to any server to do this. Well, I am not sure. The price for the certificate is the not the issue, but it is a lot of other stuff that must be lined-up to make this work which I might not will do. But, I mean I will do exactly the same as I described above. Since it seems that you have it all lined-up just do it. If something goes wrong start over.
In your case you say “My Comodo PositiveSSL (.crt) can be converted but to what and its generated with no password.” There you have the .crt file and need to convert it to .pfx. You did not use a password so in the NCS config file where it says
<add key="WebServerCertificatePass" value="test" />
omit that line completely or write
<add key="WebServerCertificatePass" value="" />
You have to test which works.
