What is a Comodo SSL certificate?

Is Comodo a Certificate Authority?

From Comodo's SSL server cert page: SSL Server Certificates are self-signed certificates used to secure any website using SSL.

Self-signed certificates are the industry standard method of securing websites, as they have none of the problems that can be associated with third-party certificates, such as CA/Browser Certification Authority (CAA) trust problems, or being restricted to a single domain.

The first thing that pops into my mind is, "Are these certificates trusted?" My first thought, without even having looked into it, is that these self-signed certificates should be trusted because the author is clearly a CAnd if a CA claims that they are self-signed, shouldn't the user trust them and accept them? After some research, I found this web page where it claims that Comodo is a CIt also says, "The list of authorities we trust is not an exhaustive list of all CAs that can be trusted." Does that mean that Comodo does not trust itself? Is Comodo really a Certificate Authority? As stated above, the first thing that comes to mind is whether Comodo is a CThe reason for this is that it is one of the biggest CAs in the world and it is the one we use, but what if the company is actually a Certificate Authority? To answer this, let's look at the certificate first, which is a signed X.509 certificate. A digital signature is an electronic way of proving someone's identity. So, in order to be considered a CA, a certificate has to have the following properties.

Signed by an authority (in other words, the issuer). This certificate is meant to be used to verify the identity of the person or entity represented by the certificate. In other words, the issuer of the certificate (the CA) is supposed to be who they say they are.

So, if this certificate is meant to be signed by another authority, it would have to be signed by a CA that Comodo has listed as a trusted authority. Which certificate was signed by Comodo? It is the second certificate that is shown here on the page.

The question is, if a CA is listed as a trusted authority, is that certificate trusted? Well, in my opinion, this certificate is not trusted.

How do I get a Comodo certificate?
