What is SSL? How To Install It?

What Is An SSL?


SSL stands for secure socket layer protocol, responsible for communicating securely between client and server. It is a standard technology that keeps internet connections safe and safeguards communication. It uses an encrypted algorithm to scramble the data in transit, preventing hackers from reading it as it is sent over the connection. The information can be sensitive or personal, which may include credit card numbers, bank details, or any other personal or financial information. 


Transport layer security (TLS) is an updated and more secure SSL version. We provide SSL TLS with the option of ECC, RSA or DSA program. As a result, HTTPS(Hyper Text Transfer Protocol Secure) appears in the URL when a website is secured with an SSL. In addition, the certificate details, including issuing authority and website owner's name, appear on the lock symbol of the browser bar. 

Domain Validation SSL Certificate: These certificates require businesses to prove their control over the domain name. It contains the domain name that was supplied to the authority for issuing purposes. Domain-validated certificates are the most basic level of SSL certification and are only appropriate for test servers.

Organisation validation SSL Certificates: This certificate requires the applicant to provide not only their domain name but also the company name. The issued certificate acts as proof of domain and company name.  

Extended Validation SSL Certificates: This type of SSL helps protect users from providing details to fake websites. Many criminals are there waiting for the user to leave personal information, and they use it for phishing. Therefore EV SSL requires validation for both the domain and company, as well as several additional verifications. 

How Does An SSL Create A Secure Connection?

When a web browser tries to access a website that is fully secured with SSL, the browser establishes a secure SSL connection with the web server., which we call a handshake. This handshake is totally invisible to users and happens instantly. Further, three keys are mainly used to create a strong SSL connection, private key, public key and session keys. Any information encrypted with the public key can be decrypted with the private key only. The whole encryption and decryption process takes a lot of processing power. So after the 

a secure connection is made, and the session key is used to encrypt the data.

  1. Browser: it connects to the web server(website) secured with SSL(https). Browser requests the server identifies itself.
  2. Server: It sends a copy of its SSL, including the server's public key.
  3. Browser: It checks the certificate root against the list of trusted CAs, and that the certificate is unexpired, unrevoked, and its name is valid to the website it is connecting with. If the web browser trusts the certificate, it creates, encrypts, and sends back a symmetric session key using the server's public key.
  4. The server decrypts the symmetric session using the private key and sends back an acknowledgement encrypted with the session key to start the encrypted session.
  5. The server and browser encrypt the transmitted data with the session key.

How To Distinguish The Areas Where SSL Is Needed? 

A site with active SSL makes a website more trustable and secure in the eyes of visitors. People usually visit such sites more often, which are fully secured with SSL. There are many reasons to embed an SSL with your site.

Secure Purchases: According to business insider, 74% of shopping carts are abandoned, but up to 64% are recovered with better checkout security and flow. Many of this, 64% of people are likely to make a purchase if they think checkout is secure.

Memberships: If a website offers memberships or anything involving email address collection or sensitive data, SSL implementation is surely a good idea.

Use Of Forms:  If any kind of form is used where users will be submitting the information, it is surprising how information is collected about the site's visitors, and it is worth keeping it safe.
