I'm trying to get a valid secured environment for HTTP communication to behave like normal ones. I'm doing this for a restricted group of users.
There is a hardware server running a web service (nginx). OpenSSL is installed on this machine and I'm using it as a CA as well. I have created the root CA certificate and I have signed a certificate for the web service using it. Then I have provided the root CA certificate to a trusted user (another PC controlled by me) and it was imported to Firefox as a trusted authority.
Almost everything works fine (the HTTPS service is accessible and the warning page doesn't appear), but I get a blue status (the first thing in the address bar, before https://... ) of the service stating:
Youy are connected to example.com which is run by (unknown) Verified by: MyCA Company
Other world-wide known HTTPS sites like addons.mozilla.com, for example, show a green status and they don't have this (unknown) piece of data. They have there the company name and location.
Is it possible to get a custom private secured environemt behave like a normal one and be green? If yes, what should be done in order to get this (client-side? server-side?) ?
As a side-effect question: where could I learn about PKI, SSL, an all this stuff from 0 to advanced? or maybe there are some good books related to this?
Thank you in advance for any help and answers.
