The SSL certificate can be described as a type of digital certificate that validates a website’s identity and allows for secure connections. SSL is a shorthand as Secure Sockets Layer, a security protocol that establishes an encrypted connection between a server on the internet and a browser.
Businesses and organizations must incorporate SSL certificates to their websites in order to secure transactions on the internet and keep confidential and secure information about customers.
In a nutshell: SSL keeps internet connections safe and stops criminals from accessing or altering information that is that is transferred across two different systems. If you notice the padlock icon beside your URL’s address in the bar at the top, it signifies that SSL secures the site you’re on.
Since its creation around 25 years ago There have been a variety of versions of the SSL protocol that all eventually ran into security problems. A redesigned and changed name was then introduced the name Transport Layer Security that is being used in the present. But the initials SSL were not changed, so the current TLS version is commonly referred to by its old name.

What is the process behind SSL certificates function?
SSL ensures that data sent between websites and users, as well as between systems is unreadable. SSL employs encryption techniques to scramble data while in the process, preventing hackers from gaining access to it when it travels via the network. The data may contain sensitive information, such as addresses, names credit card numbers or any other financial information.
The procedure works as follows:
- A browser or server tries in connection with a site protected by SSL.
- The server or browser requests that the web server identify it.
- The web server will send the server or browser a copy of their SSL certificate as a response.
- The server or browser checks to determine if it is able to trust its SSL certificate. If it is then it transmits this information to the webserver.
- The web server will then return an electronically signed acknowledgement to begin an SSL secure session.
- Data encrypted is transferred between the browser or the server as well as with webserver.
The process is often called the SSL handshake. Although it may sound like a long process however, it happens in milliseconds.
If a website is protected with using an SSL certificate, an word HTTPS is displayed within the URL. If the website is not secured by an SSL certificate just the letters HTTP are displayed without the S which stands for Secure show. The padlock symbol will be displayed on the bar for URL addresses. This is a sign of trust and offers security to visitors to the site.
To look up the SSL certificate’s information to view the certificate’s details, click the padlock icon in the browser bar. The typical information contained in SSL certificates are:
- The domain name this certificate was created to was
- Whom, who’s organization or device it was assigned to
- The Certificate Authority issued it
- The digital signature of the Certificate Authority
- Subdomains associated with the subdomain
- Date of issue of the certificate
- The expiration date for the certificate
- A public secret key
What are the reasons you should have an SSL certificate?
Websites require SSL certificates to ensure that the security of user data, confirm the authenticity of the website and stop hackers from constructing an untrue version of the website and also give confidence to the users.
If a site is asking users to sign up and enter personal information, such as number of credit cards, to view private information like financial or health benefits It is crucial to ensure that the information is kept private. SSL certificates can help ensure that online transactions are secure and ensure that the site is legitimate secure to disclose their personal details with.
For businesses, it is more important the requirement for it is mandatory to have an SSL certificate is required to establish an HTTPS website address. HTTPS is the secure version of HTTP and this implies that HTTPS websites have their data secured by SSL. A majority of browsers label HTTP sites that are not equipped with SSL certificates that do not have SSL certificates – in the form of not secure. This is a clear warning to the user that the website could not be trusted and encourages businesses that aren’t yet ready to move to HTTPS.
An SSL certificate can help secure data like:
- Login credentials
- Bank account details
- Personally identifiable information like full name address, date of birth, or even a telephone number
- Contracts and legal documents
- Medical documents
- Private information
Different types of SSL certificate
There are a variety of SSL certificates, each with different levels of validation. The six major types are:
- Certificates with Extended Validation
- Organization-validated certificates
- Certificates that are Domain-Validated
- Wildcard SSL certificates
- SSL certificates that are multi-domain
- Unified Communications Certificates
Extended Validation Certificates
It is the top-ranked and most costly kind of SSL certificate. It is typically employed for sites with high-profile that gather data and require online transactions. Once installed, this SSL certificate shows an encrypted padlock HTTPS and the company’s name, company, as well as the country in the address bar. Displaying the information of the owner of the site within the address bar can help to distinguish legitimate sites from fraudulent websites. To establish the EV SSL certificate the website’s owner has to undergo a common identity verification procedure to ensure that they are legally authorized to hold the sole title to their domain.
Organization-validated Certificates
This type of SSL certificate comes with an assurance level similar to that of it’s EV SSL certificate, as to be able to obtain one, the owner of the site must go through a lengthy verification procedure. The certificate also displays the information of the owner of the website on the bar of address in order to distinguish from fraudulent websites. This type of certificate is also known as OV SSL certificates are generally the second-highest priced, and their primary function is to protect the personal information of the user when making transactions. Websites that are public or commercially-oriented must have an OV SSL certificate to ensure that all personal information provided by customers remains private.
SSL certificates that have been validated by Domain
The process of validation to get this SSL certificate is minimal which is why, Domain Validation SSL certificates offer less assurance and lower encryption. They are typically utilized for blogs or other informational websites, i.e. they do not require payment via online or data collection. This SSL certificate is the cheapest and expensive and fastest to acquire. The process of validation only requires webmasters to verify that they own the domain by replying to an email or a call. The address bar of the browser only shows HTTPS as well as a padlock, but with no company name visible.
How do I get an SSL certificate?
SSL certificates are available directly through the Certificate Authority. Certificate Authorities often called Certification Authorities are the ones who offer thousands of SSL certificates every year. They play a crucial part in the way that the internet works and how secure, transparent interactions can take place on the internet.
The price for an SSL certificate can vary from zero up to thousands of dollars dependent on the degree of security you want. After you have decided which kind of certificate you need You can then search for Certificate Issuers that provide SSLs that are at the level you need.
The process of obtaining your SSL is as easy as following the steps:
- Start by getting your server up and running, as well as make sure you have your WHOIS record is up-to-date and matches the information you’re sending for the Certificate Authority it needs to have the correct name of your company and address as well as other information.

Does An SSL cert be used for multiple server?
You can use the same SSL certificate to access multiple domains on one server. Based on the provider you may also be able to make use of one SSL certificate for multiple servers. This is due to Multi-Domain SSL certificates, which we’ve discussed in the past.
The name suggests Multi-Domain SSL Certificates work using multiple domains. The exact number of domains can be left to the particular issuing Certificate Authority. The Multi-Domain SSL Certificate is a Multi-Domain SSL Certificate is different from one called a Single Domain SSL Certificate, that – like the name suggests – is created to protect only one domain.
What happens after an SSL certificate is canceled?
SSL certificates aren’t resold; they’re not guaranteed to last for long. The Certificate Authority/Browser Forum, which is the main regulator for the SSL industry, says SSL certificates should last less than 27 month. This is basically that you have two years and can carry forward up to three months, if you renew using the remaining time on the previous SSL certificate.
SSL certificates expire due to the fact that they, like all forms of authentication, data needs to be regularly validated to verify that it’s correct. Things are constantly changing on the internet as businesses and websites are sold and bought. When they are sold the information related to SSL certificates changes too. The reason for the expiry time is to make sure authenticity of servers and other organizations is as current and precise as is possible.
