SLL Web Hosting

When we talk about web hosting SSL, were usually referring to SSL certificates. What is an SSL certificate? An SSL certificate is a digital certificate that is issued by the relevant certificate authority (CA).A certificate is a unique number that allows a domain name to be digitally authenticated. It is a kind of ID for your online presence. The name of the CA that issues the certificate is often mentioned as well. This is one of the most important things to know about SSL certificates.

A SSL certificate is issued when the relevant certificate authority (CA) issues a code or digital certificate with that name. Once a certificate has been issued, it can only be trusted for domains that are hosted by the issuer of the certificate, so if you keep your web host private, the site can only be accessed by you or someone who knows the private key to the certificate that was used to generate it. In other words, if you use your own web host to host your content, and you keep your keys in a safer place, then you will be protected, and there are also services that offer knownhost dedicated servers which is a good and secure option as well. (If you want to understand more about this, you should read. The Basics of SSL.)

Types of SSL Certificates
There are a variety of SSL certificates that are used in the world of digital certificates. The most common are:
Domain Validation SSL (DVSNI)
Domain Validation SSL certificates are created by a CA that consists of two parts: a domain validation certificate that validates that the domain for which the certificate is being used is using the right domain name, and a public key to be signed by the CA (called the root certificate).
These certificates can either be issued for a particular domain name (Vulnerable and Valid) or for all domains of the domain name (Adequate and Necessary). There are many more types of SSL certificates than that, including ones that can be issued for specific email addresses (Valid Email Subject), SSL certificates that can be issued for specific security questions (Verified Authentication), and one called an intermediate certificate that can be used as a back-up.
Let’s take a closer look at the three types of certificates. The one we will discuss today, the Domain Validation SSL certificate, is useful for a small number of sites. This is because a lot of the clients we come across (the browsers and operating systems) will reject domain name certificates with a subject string that contains space (sounds like two-letter acronyms), like ssl.domain.com. The client also will reject domain names with a subject string of ., which is also used for security questions. These problems are what can sometimes be “fixed” with a domain validation certificate, as discussed below. But for a lot of sites, these problems can’t be fixed. Thus, the Domain Validation SSL certificates tend to be used when the site needs to be valid for many websites at once.

Domain Validation SSL certificates usually have a lower length than Necessary and Adequate certificates, which is useful for sites that need a larger certificate (say, a 1,000,000 word novel). Also, this higher length means a small, transparent number will be generated. Let’s take a look at an example of this in action.
