Sure, it's possible. But very expensive.

You need to convince major browsers to include your root certificate in their browser. That will require assuring the browser makers that you are reputable, and will probably also require some (very considerable) payment.

Then you have to wait for new browsers that have your root certificate embedded to come into general use - which will take several years.

Now, if you want to have a website that issues certificates that aren't of any real use to anyone (because the root certificates aren't included in browsers by default) - now THAT is easy!

But there would be no point in it. Anyone with a Linux system or a Windows server can create self-signed certificates and/or certificates under their own certificate authority.

CACert is an attempt to make certificates available at no cost. However, they have not yet convinced a major browser maker to include their root certificate by default.

Its very nice what you told me, more knowladge of course..

you said also something very useful for me, which is:

"But there would be no point in it. Anyone with a Linux system or a Windows server can create self-signed certificates and/or certificates under their own certificate authority."

Thats something in need very much, at least to be sure that the emails that i use on my server are secured, and some other website that i mainly use them and some friends,

How exactly to do the self-signed certificates or the sertificates under my own authority?

Thanks
