What is SSL?
Have you ever seen that some URLs start with “http: //” while others start with “https: //” ? You might have noticed that when you browse websites like banks, online payments, you need to provide sensitive information, such as when you pay online bills. What is SSL? Definition and how SSL works.
But where did the additional “S” come and what does it mean?
To keep it simple, additional “S” means that your connection to that website is secure and any data you enter is securely encrypted. The technology that gives “s” less power is called SSL.
SSL is a standard security protocol for server and server to install encrypted links in web browsers. This link ensures that the data between the browser and the server is safe in the exchange.
SSL Complete Form
There is a complete form of SSL –
Secure Socket Layer
SSL (Secure Sockets Layer) is an encryption technology employed by websites to protect connection between site and their site visitors.
The most widespread use of SSL is secure on pages where users should provide sensitive information such as credit card numbers or login details.
In recent years, website owners have been encouraged to implement SSL encryption across its entire site, major search engine providers have provided SEO benefits on https pages.
SSL encryption is particularly useful for e-commerce websites because it helps them build trust with their clients.
“SSL is a standard security technology for setting up an encrypted link between the web server and the browser, ensuring that all the data between the web server and the browser remains private.”
Let’s understand it deeply.
When you are on a website page it has a form, you can fill it out by filling out the form and clicking on the ‘submit’ button, the information you enter may be intercepted by the hackers on unsafe websites.
This information may be anything from the details given on the top level information for any bank transaction, which you would like to enter into the listing for the offer.
In Hacker Lingo, this “interruption” is most often referred to as “man-in-the-middle attack”. Actual attacks can take place in many ways, but the most common thing is: A hacker keeps a small, unbelievable program on a hosting server. The program is waiting in the background because visitors start writing information on the website and when a person fills his information, the program starts broadcasting that information, and then it comes back to the hacker. It looks scary to be active, but it is not a science-fi movie.
Distribute it when you visit an encrypted website with SSL, your browser will create a connection with the webserver, view the SSL certificate, and then connect your browser and server. This binding connection is secure, so there is no other one except you and the website that you are typing in your browser and viewing the information you are submitting.
This connection occurs instantly, and many people think it’s faster than connecting to unsafe websites. All you need to do is get a website with SSL and your connection will be automatically secured.
Internet security and secure online behavior
As companies and organizations offer more online services and transactions, their online business requires Internet security, prioritization, and sensitive information – such as credit card numbers – for legitimate online business communications only.
What Do They Need for SSL Certificates?
SSL Certification Data is an important component of the encryption process that secures internet transactions. They are digital passports that provide authentication to protect the privacy and integrity of website communications with browsers.
The work of SSL certificates is to start secure sessions with the user’s browser through the secure sockets layer (SSL) protocol. This secure connection can not be installed without SSL certificates, which digitally associates company information with a cryptographic key.
Any organization that engages in e-commerce should have an SSL certificate on its web server to ensure customer and company information, as well as to ensure the security of financial transactions.
Important of SSL
Why is SSL important?
The primary importance of establishing SSL certificates is to start a secure session between the web server and the browser. Once a secure connection is established, then all the information passed between the web server and the visitor will be kept private and encrypted.
1) Improves customer trust
In the URL, this small customer assures the customer that their information will not be compromised. The data will be sent to the desired target server, and it will not be redirected to the unauthorized third party. Prior to receiving SSL certificates, CA will validate the authenticity because it only distributes SSL certificates to real companies and businesses.
2) Protects information against phishing attacks
Phishing sites are fraudulent copies of famous websites, whose purpose is to deceive you into making valuable information such as your credit card or bank details.
Phishing sites often have similar forms and visions of the original site, but the website’s adress is different and it is usually not secure with SSL certificates.
For example, PayPal.com is a popular target for these fake, copy-cat phishing sites. Extended validation certificates prevent you from phishing attacks by displaying the full business name of the owner of the website in the address bar. Phishing site operators can not get EV certificates due to extensive verification requirements.
3) Better search engine rankings
HTTPS is now considered one of the world’s largest search engines, as a ranking signal by Google. If you are optimizing, you should consider getting SSL certificates to help increase your ranking, especially for ecommerce sites.
Disadvantages of SSL
With so many advantages, why would not anyone use SSL? Are there any disadvantages of using SSL certificates? Cost is a clear loss. SSL providers need to establish a reliable infrastructure and validate your identity, so this includes a cost. However, the growing competition in this industry and the introduction of providers like Let’s Encrypt have made it very slow.
There is one more disadvantage with performance SSL. Because the information you send is encrypted by the server, if the information is not encrypted it takes more resources than the server. The difference in performance for web sites with a large number of visitors is only noticeable and in such cases, it can be reduced with special hardware.
Overall, the disadvantages of using SSL are very low and the advantages are very high. It is important that you use SSL properly on all websites. Proper utilization of SSL certificates will help protect your customers, help protect you, and help you gain more trust from your customers and sell more.
How SSL Certificates Work
A user requests the web address that starts with https: // using their internet browser. The browser requests that the server itself identify it.
The server replies by sending a copy of its SSL certificates, which contains its public key.
The browser checks for the certificates root to know whether it relates to a trusted CA. It also checks whether the SSL certificate has been uninstalled or not. In addition, it checks if its common name is valid for the website.
Once the browser has confirmed that it is dependent on the website, it encrypts the server’s public key and sends it back to a symmetric session key.
Now, the server has decrypted the symmetric session using its own private key.
Conversely, the server sends the encryption receipt with a session key to enable an encrypted session.
Now, all the data transmitted between the server and the browser is encrypted.
Problems with SSL certifications
Who does the SSL certificate?
SSL certificates are issued by Certificate Authority (CA), along with other digital certificates. They confirm the identity and ownership of the business or company for the certificate. These issued certificates are the chain of trusted credentials owned by your chosen CA. Trusted certificates are embedded in the “Certificates Store” in a popular web browser such as Firefox, Chrome, Internet Explorer and Safari.
When you visit a website that uses SSL certificates, it checks that your browser signature with one of the trusted root in its store. If not, will warn you that the connection is not secure. An error message will also be visible to everyone coming to your site. That is why we recommend buying only SSL certificates from reliable CAs.
How do I apply SSL to my site?
How do I apply SSL to my site?
Setting up SSL on your website is easy! In general, these are 3 simple steps for installing your new SSL certificates.
1) The certificate purchase issued by a reliable CA
Trusted certificates can be purchased from your web-host or purchased directly from other reliable CAs. Certificates from a trusted CA will be accredited by all popular internet browsers used by your visitors (Chrome, Firefox, Internet Explorer, Safari etc).
2) Activate and install the certificate
If you have purchased your certificates from your web-host then they can take this step for you. If you are manually managing the site, then you need to complete the two steps, one of them is a certificate signing request (CSR) and then install your certificates.
3) Change your entire site to HTTPS
After installing your certificates on your target pages, modify your site so that all content can be safely served. Internet is rapidly moving towards a default HTTPS for every page, and if a website is served more than HTTPS, Google is also offering better search rankings to websites.
Types of SSL
What are SSL types?
Due to the different demands of websites around the world, SSL certificates are in a variety of different types. The main validation level is the Extended Validation Certificates (EV) and Domain Validated Certificates (DV).
Each type of user has different levels of confidence. Let’s talk about these levels of user-
1) Extended Validation Certificates
EV certificate provides the highest levels of security, trust and customer conversion for online business enterprises. Only after issuing an EV certificate, the company gets strict background checks about the company as per the guidelines laid down by the Certificate Authority / Browser (CA / B) Forum. Because of this, there is a specific difference in the EV certificate, which is clearly designed to clarify the reliability of the website for its visitors.
Whenever a website goes to EV certificate, address bar in green browsers like Internet Explorer, Firefox and Chrome will be green. EVs certificates are used by all major online retailers and banks and are highly recommended for businesses who want to instantly create customer trust in their site.
2) Domain Validated Certificates
DV certificates provide high data encryption similar to EV and OV but do not provide assurance about the identity of business behind the website. While the EV and OV certificates are issued manually by the Certificate Authority, the application is released only after the application is issued, DV certificates are issued after the domain control is installed using an automated, online process. DV certificates are a popular option among small and medium sized web sites because they are released faster and cost is less.
