SSL Certificates

SSL (Secure Sockets Layer) is one of the standard security protocols used by millions for establishing an encrypted connection between a web browser and a web server while preventing cybercriminals from reading and modifying any transaction done between them such as the transmission of sensitive information like credit card while doing online shopping. It ensures that all the data passed between the web browser and web server remains private and secured.

Domain Validated SSL certificate is best for personal blogs or websites Organization Validated SSL is good for the organization’s website which has to deal with critical data Extended Validated SSL certificates are good to go for any shopping portal or any website which does financial transactions online such as Banking website.

Whenever a user visits a secured website, an SSL/TLS Certificate installed on it offers identification information regarding its web server and creates an encrypted connection. Furthermore, all of this process is done within a second. Let’s see how does an SSL work? Web browser or server tries to connect with the server of a website secured with an SSL/TLS Certificate and make a request to a web server for identifying themselves. Copy of a web server’s SSL/TLS Certificate is sent to the browser or server. Once the browser/server receives it verifies whether to trust the SSL/TLS Certificate and then sends a message to the web server. The web server sends back an acknowledgment in a digitally signed format for starting an SSL encrypted session. Now, the access is granted to share encrypted data between the web server and the browser/server.

Yes. If you have a website/WebApplication, SSL is needed. Earlier, it was okay to have an SSL only for the website which was collecting information from the user. But after Google’s update regarding SSL, it is needed no matter what type of website you have, whether you collect the information or not. Even a simple blog will also display a “Not Secure” if the SSL is not installed on it.

Both TLS & SSL are protocols used for sending data over the internet securely. Though there’s a minor difference between them, still TLS and SSL are considered as a different standard. TLS (Transport Layer Security) is an advanced version of SSL (Secure Sockets Layer), which uses stronger encryption algorithms and also has the ability for working on different ports. Furthermore, TLS versions do not work in conjunction with SSL version 3.0.

Getting an HTTPS on the website is quite easy. Simply follow the below steps: Get your website on a dedicated IP address Purchase a certificate from the trusted Certificate Authority or its resellers Activate the purchased SSL/TLS Certificate by following all the necessary steps such as generating CSR Install your SSL/TLS Certificate Finally, make the necessary changes to use HTTPS

SSL/TLS Certificate works on RSA Asymmetric Encryption and Symmetric Encryption. Where Asymmetric Encryption helps to establish a secure client-server session and Symmetric Encryption for exchanging information securely over the already established secured session, also called as “SSL Handshake.”
