What is an SSL Certificate?

A “Secure Sockets Layer” or “Transport Layer Security” certificate is a license that ensures the protection of a website from hackers, man-in-the-middle attacks and, any other vulnerabilities. These certificates make sure that the data exchange between the user and the server is safe from the reach of scammers by encrypting the information.

An SSL certificate can take your online business tothe next level of security. When the users visit a site having a valid SSL certificate, they feel comfortable in sharing their personal information on that site. This builds a trust relationship between the users and your site, which translates to better sales and conversions. Also, a web server having an HTTPS connection ranks higher than insecure pages in search engine rankings. So, to get these advantages, you should buy an SSL certificate for your site. SSL certificates are now very common and you can buy cheap SSL certificates from any of the famous SSL certificate providers.

Types of SSL certificates

 

1)    Single Domain SSL Certificate

These types of certificates are used for only one domain. All pages on this domain are also secured with this license. For example, if clickssl.com has a single-domain SSL certificate then clickssl.com is safe with this certificate. This certificate cannot be used for subdomains.

2)    Wildcard SSL Certificate

After having wildcard ssl certificate, a domain and all of the subdomains under that domain are secured.  For instance, www.clickssl.com has subdomains including resource.clickssl.com, pricing.clickssl.com, etc. Each subdomain is under the main domain (clickssl.com).

3)    Multi-Domain SSL Certificate

As the name indicates, a multi-domain SSL certificate is used for numerous domains. The domains share the certificate and the subdomains of the main domains are also secured with this single certificate.

Types of SSL Validation

Although all the SSL certificates perform the same task of encryption and decryption, the validation level makes them different from each other. There are three categories of SSL certificates based on their validation level:

1)    Domain Validated SSL Certificate

This is the basic form of SSL certificates. In this type of certificate, you provide the domain name of your website to certification authorities. The certification authority checks for the validity of the domain name you provided. You can get this certificate in a few minutes. These certificates are suitable for small businesses, blogs, or resume sites.

2)    Organization Validated SSL Certificate

If you are running an organization, then you must get an OV SSL certificate. To get an OV SSL certificate, you need to provide a domain and the business details to CA. The certification authority will check for the domain and will verify whether your business is legitimate or not. The verification process is done by humans that’s why this certificate may take several days to get issued. Also, this certificate is expensive than the DV SSL certificate but it provides betterprotection of the webserver and the other online businessproperies. OV SSL certificates are beneficial for sites that acquire personal information from the users.

3)    Extended Validation SSL Certificate

An EV SSL certificate is the strongest of all. Although it is very expensive, it is the best for the web sites dealing with banking details, addresses, etc., of the users.

This certificate can take 2-3 weeks to get issued from CA because in this certification a higher human interaction is involved. The certification authority performs a full security check of the domain, organization/business, their address, the authenticity of the business, etc.

You can check the certificate type of a web site by clicking on the padlock on the left side of the browser.

As a browser checks for the validity of the certificate at first and then sees the redirect. If you have removed the old certificate, then Google may find it difficult to understand this migration.

John Muller, who is Google’s webmaster and trend Analyst confirmed that browsers require an SSL certificate even when you are redirecting. He further said that maybe search engines can handle this, but if for some reason, you need to show the certificate to your users, then you have to keep paying for the old SSL certificate too.

2)    Old Certificate Should Remain on The Site for Six Months

John Muller has also suggested that you should keep your old certificate on the site for six months. The reason for this is that Google re-crawls URLs two times in a year.
