As with development and popularity of the internet, sending and receiving information online has never been a problem. Along with that is the increased risk of security threats like phishing attacks, virus attacks, unauthorized viewing, or data tampering. Surprisingly, there still are many webmasters don’t fully understand how to make use of security tools at their disposal to protect their website from cybercriminals or hackers.
What Is SSL?
Secure Socket Layer Certificate, also known as SSL Certificate, is a widely-used security solution nowadays to helping defend against malicious code that can damage your system and against cyberthieves on the lookout for sensitive data to sell on the black market. And in addition to securing your website’s connection for users, an SSL certificate can also boost the website’s search engine rankings. So, if you’re running an e-commerce website or any other type of website that involves in user data collection, every single word in this article is of value and needs extra attention and learning.
How Does SSL Certificate Work?
If your website enables an SSL certificate, the browser will automatically establish an SSL connection to the web server through the process of “SSL Handshake”. The SSL Handshake keeps invisible all the time and starts working instantaneously whenever the browser attempts to access your website.
Essentially, the SSL connection is set up with three keys, including the public, private and session keys. Anything that is encrypted with the public key can only be decrypted with the private key, and vice versa.
Since it needs a lot of processing power to encrypt and decrypt with the private and public key, they are only used during the SSL Handshake to generate a symmetric key. Once the secure connection is created, all transmitted data will use the session key to keep security.
- Browser connects to a web server secured with an SSL certificate. The web server is required to identify itself by the browser.
- The web server sends a copy of its SSL certificate to the browser, including the public key.
- Browser takes a check of the certificate root against every trusted CA on the list, verifies whether it is expired and revoked. As soon as the SSL certificate gains trust from the browser, an encrypted symmetric key will be generated and sent back to the web server.
- The symmetric key is decrypted by the web server using the private key. At the same time, the browser sends back an acknowledgement which is being encrypted using the session key and will be used for triggering the encrypted session later.
- All transmitted data is encrypted by the browser as well as the web server in the help of the session key.
SSL: Not Only for Visitors But Also for Your Business
Almost every SSL certificate contains if not all, at least part of the information as the domain name, business name, address, city, state and country, in addition to the details of the CA and a period of validity. A browser usually would make sure the certificate is still within the effective period and is issued by a trusted CA when it tries to establish an SSL connection. It displays a warning to let you know that the site is not secured by SSL if any of the checks fails.
According to a research conducted by Gartner, 70 percent of people shopping online have given up an order because they didn’t trust the website. What’s more, 64 percent of those shoppers expressed their willingness to finish the transaction if the website had a trust mark or SSL certificate. In other words, an SSL certificate not only protects both customers and internal data, it creates safer experiences for the customers, therefore building customer trust and improving conversion rate.
Importantly, HTTPS has significantly affects Google rankings. The world’s largest search engine is storing the data of Crawling and Indexing in your website SSL certificate and considers HTTPS as a ranking factor. Clearly, websites having SSL certificate are boosted in the search rankings besides providing solid security during information transfer.
What Type of SSL Certificate Should You Use?
It can be a real challenge to choose an SSL certificate for you website, after all there are many types of SSL certificate with confusing names, without saying a bunch of Certificate Authorities boasting about affordable, powerful SSL certificate solutions. However, your final decision of an SSL certificate should be based on the level of security your website requires and how much money you plan to invest in it.
Domain validated certificate is the most basic type of SSL certificate, but also known as a low assurance certificate since the CA issuing the certificate by only verifying the website’s ownership.
You’ll be asked to offer documentation for proving that you own the domain that you wish to protect and the validation can be confirmed simply via a standard email.
The whole verification process can typically be completed in a few minutes.
Suitable for websites where visitor trust is not of high importance and information like usernames, passwords, or credit card information is not required.
Organization validated certificate is a high assurance certificate. Besides the domain ownership, CAs also confirms that your organization is legit before issuing an OV SSL certificate. Because of that, organization information like name, city, state, and country is required to offer for verification.
This type of SSL certificates typically take between 2 to 3 days to be issued.
Suitable for businesses and companies who are interested in going beyond standard encryption and beefing up their trust.
Extended validated certificate, usually in the form of a green padlock on visitors’ web browsers, comes with the highest level of security and authentication. The verification includes the most tedious and vigorous process, requiring webmasters to ensure they’re actually a legitimate business, in addition to offering business information as a proof of domain ownership.
It typically takes longer to complete the thorough validation process.
Suitable for ecommerce sites or other mission-critical websites that need to communicate a high level of trust to users.
The above SSL certificate types are categorized based on different validation level. They can also be classified into different groups in accordance with the number of secured domains/subdomains, namely, single-domain SSL certificates, wildcard SSL certificates, and multi-domain SSL certificates.
- A single-domain SSL certificate supports protecting only one hostname or subdomain.
