Who issues an SSL certificate and where to buy an SSL certificate?

The SSL certificate is issued by the operator. The operator is the service provider that sells us the SSL service under a license that is issued by a major Certification Authority. Publishers include. CERTUM, RapidSSL, Datacard, Digicert, geotrust, etc. Of course, we can buy the certificate directly from them, but also through intermediaries such as. LH.co.uk

What to choose an SSL certificate - what is an SSL certificate and why I need one. Free or paid...

Let me start by saying that an SSL certificate is almost no different from any other SSL. The difference is really in the warranty. Back in the day, the look of an SSL certificate was different. In the URL bar, the company name appeared with all the green button (button). Currently, all browsers show a closed padlock stating the connection is secure. In addition, we can check the SSL type and certificate issuer.

In truth, only banks have a top-down requirement to secure sites in more enterprise solutions. This is rather understandable.

If anyone were to ask - why do I need a warranty with SSL. The SSL certificate guarantee ensures that if someone breaks its key then we will receive, for example, 15 thousand, 30 thousand, 500 thousand, 1 million dollars of course - depending on the amount of insurance. The amount of insurance is, of course, related to the choice of more expensive SSL certificates.

Let's Encrypt's free SSL has no guarantee. However, its parameters are the same as any other. Auto-renewal, domain validation, 99% web recognition, etc.

Let's Encrypt

As I mentioned earlier, this type of SSL certificate is free. They are no different except for the warranty. There are limitations, but we do not feel them. The limitation is that such a certificate must be renewed every 90 days. However, when we are with an operator/service provider like. Light House is it on their side and we don't have to worry about anything. Back in the day, Let's Encrypt did not support wildcart. This is now standard.

All documentation and the project website is available here: https://letsencrypt.org/

What an SSL certificate used to look like

I mentioned earlier about the looks of the SSL certificate. It will show how the certificate has looked over the years.

SSL Certificate - WildCart. SSL certificate for a domain, and for a subdomain what is the relationship

In a nutshell, when we take an SSL certificate with the wildcart option then our domain will have a padlock on all subdomains as well. NOTE! SSL works to the second subdomain namely: kamikstudio.pl and forum.kamikstudio.pl

If we implement wildcard on kamikstudio.pl then for: web.forum.kamikstudio.pl will no longer work.

We must remember that the subdomain is already kamikstudio itself, because the domain is .pl and the other subdomain for kamikstudio.pl is dev.kamikstudio.pl.

We can implement a wildcard for the second level subdomain, then it will work to the third web.forum.kamikstudio.pl but no longer to the first kamikstudio.pl

These are, of course, strong details, but they are worth mentioning.

What is an SSL/TLS certificate

SSL is a protocol that secures communications on the site. The messages we send from us to the site. SSL is mainly popular for login systems. As you log into the bank you enter your ID or login and password. SSL protects so that your connection is encrypted

SSL/TLS is an extension of SSL. TLS is what ensures the confidentiality and integrity of data transmission, as well as authentication of the server and sometimes the client. It is based on asymmetric encryption and X.509 certificates.

Currently, the latest TLS is version 1.3 and SSL is version 3.
