The SSL certificate for websites is a cryptographic protocol which offers communication security protocol over the Web. When a sender sends sensitive information over the Web, SSL helps protect that information with robust and reliable encryption. Therefore, hackers or outsides are unable to intercept that information and user’s data remain secure and safe online. Several certificate authorities provide the SSL certificate that comes with up to 2048-bit RSA key and256-bit encryption. Since SSL came into existence, the size of encryption is increasing periodically such as 40-but, 56-but, 128-bit, 192-bit and even 256-bit encryption. The Certificate Authority Bureau (CAB) forum changes the algorithms of SSL standards occasionally.
What Happens When A Browser Connects To An SSL Secure Site?
- The very first step here is that the Web browser attempts to connect to a website.
- The browser then demands the Web server to verify whether the site is equipped with SSL security or not.
- The server of the website than transmits a copy of SSL certification for the visitor’s browser confirmation.
- The next step here is the confirmation of the SSL security certificate.
- The Web browser then assures that the certificate sent by the SSL web server is authentic.
- Once the certificate is validated, the browser transmits a message to the web server.
- However, if it fails to verify, the browser issues a warning and stimulates the user to deny or authorize the legitimacy of the Web server certificate.
There are several different types of SSL certificates; for instance, domain validation, EV certificate, organization validation, Code Signing Certificate and SGC certificate. Each certificate has different purposes.
- Domain Validation – It is a primary domain certificate, which comes with an easy installation process. It is a cost saving certificate and is available with an affordable price tag.
- EV Certificate – This is also known as ‘Green Bar Certificate’ that turns your URL bar into a green bar and provides security against phishing and any other online attacks. Several institutions and companies prefer having an EV certificate for their website security.
- Organization Validation – This certificate authority issues business validation certificate after the business documents have been verified. It boosts customer confidence and proves that the website is legitimate.
- Code Signing Certificate – It helps the software developers in singing software code. This certificate also assures that the software code is legitimate and not altered at all.
- SGC Certificate – If you are running an old browser version which is unable to handle 256-bit encryption than SGC certificate will helps strengthen the old browser version.
Before you select the right SSL security, the website owner needs to decide on the type of SSL certificate, money back guarantee, cost, the after services and the authenticity of the SSL service authority.
