Information security on the Web is one of the main issues that site owners should pay close attention to. In the world of rapidly growing cyber threats, they need to clearly understand how to prevent data leakage or protect their resource from access to it by third parties. The installation of SSL certificates has become a modern standard for site security. However, such a protection mechanism is relatively new and difficult for the mass user. Let's understand what this technology is and how it ensures the security of information on web resources.
SSL certificates with domain verification, or as some call them, entry-level certificates are the most common in the world, and this is not surprising, because the speed of issuing such certificates varies from 2-10 minutes, depending on the brand. To obtain such a certificate, no documents are required, the whole process is extremely simple, you need to confirm ownership of the domain, and for this there are 3 ways, one main and two alternative. Entry-level SSL certificates with domain verification are one of the fastest-issued certificate types because Do not require any documents. We recommend these certificates for small sites and small projects, when you do not need a lot of trust from clients and visitors of the site, project. With such a certificate, static security logos are more often used, however there are some that offer dynamic ones, for example: Thawte SSL 123, Sectigo SSL Certificate.
Validation via Email (DCV Email) This method is described on many sites and blogs, the whole point is that the certification authority will send you a verification letter in which there will be a link to confirm ownership of the domain. Such a letter can be sent either to the e-mail specified in the Whois of your domain, or to one of the golden five: admin @, administrator @, hostmaster @, postmaster @, webmaster @ Validation via DNS CNAME A fairly popular method, for those who may not have a mail server configured, and whois e-mails are closed by private registration. The bottom line is simple, you have to make a special entry in your DNS, and the certification authority will check it. The method is fully automatic. Validation Using a Hash File (HTTP CSR Hash) An even simpler method is that you will be provided with a special .txt file that you must upload to your server, the certification authority will verify its availability and a certificate will be issued. The method is fully automatic.
Wildcard SSL certificate protects an unlimited number of sub-domains, but for the next level of domain only. If order placed for *.domain.tld, that means SSL will protect the domain.tld (base domain) and all its sub-domains (next-level), like any.domain.tld, mail.domain.tld etc, but NOT *.*.domain.tld. Basically, double wildcard certs not exist, same as EV Wildcards. It is also possible to use Wildcard SSL for mail and exchange servers, as most modern software may work with them like with UCC (Unified Communication SSL certificates).
Multi-Domain SSL certificates, also known as Unified Communication Certificates (UCC) and Subject Alternative Name (SAN). All of them solve the requirement of protecting multiple domains and sub-domains. They are very popular for companies who run various local websites. CDN (Content Delivery Networks) use them to protect all their customers. The modern SAN SSL supports up to 250 items, where each item can be used for domain or sub-domain. Some products like Multi-Domain Wildcard SSL certificates may support *.domain.tld (Wildcard domains) as SAN item.
Starting in July 2018 Google suggested making SSL certificates mandatory for all websites. That is great for us as to SSL provider, sales growing, thank you all. Owners of websites that do not have any forms, e-commerce and are just content websites curious and asking if they need SSL for their website. We are honest people here, and our answer is - No. There is no need to install SSL if there is no traffic to encrypt. Your users do not submit comments, testimonials, do not fill contact form or no other interaction with a website, just reading your posts and articles.
