The role of SSL certificates in Web Hosting is important. Especially in the event of a variety of security threats each day, no one wants to go into places which are not secure.
However, the cost of providing security via SSL is considerable as dedicated certificates require a significant amount of money. The use of SSL secure web sites is, however, useful.
The secure URL begins with 'https' rather than 'http'. The letter “s” in “https” stands for secure, which indicates that the site is using a Secure Sockets Layer (SSL) Certificate.
The majority of modern browsers now display warnings when visiting an unguarded site. Being vigilant and aware of such warnings can save us from fraudulent websites.
Usually, just before the urls listed below, Web browsers show what's happening with the site. A clear indication that the site you're going to visit is not secure is the red warning color with the 'http' protocol.
Well, yes, that's the answer. There are many certificate agencies that provide SSL certificates, and few. There are also open source organizations that, for no charge, issue SSL certificates.
Below are few options one can consider:
Let's Encrypt- It's completely free of charge to issue ssl certificates. This authority also offers automated script bots (Acme Certbot) for a painless certificate installation and renewal process, which is much easier to do.
Renewal process creates a scheduled job on deployment server which keep on checking for expired certificates and renews them as soon as they get expired.
Hosting providers are an alternate option. If you purchase a Hosting Package with them, you can get free SSL protection for your website.
Although SSLs are of the utmost importance for site security and, you may also have access to free certificates. The fact that free SSLs do not offer encryption and authentication is important to keep in mind. They shall not be able to offer the same degree of protection that is provided for by payment certificates.
Thus, The choice of certificates should therefore be made carefully, considering the nature of the Web site.
