How Does SSL Certificate Work?
As we all know, Cyber Security has become a major concern for all Internet users. An SSL certificate is by far the best and easiest solution to secure websites and the data transmitted through them from getting stolen or hacked. The acronym “SSL” stands for Secure Socket Layer and is referring to the layer that the security protocol takes place on. In laymen’s terms, it secures your websites with encryption. Let’s learn about how does SSL certificate work.
When a browser attempts to access a website that is secured by an SSL certificate, the browser recognizes the SSL and then the web server and browser establishes a secure connection or session. This process is sometimes called an “SSL Handshake”. Note that the SSL handshake happens instantaneously and remains invisible to the users.
Functions of SSL Certificate
1) SSL Encryption, which allows user to securely transmit the data over internet
2) Identity validation, which verifies whether the business is legitimate or not.
Server Browser Communication – Learn How Does SSL Certificate Work
- The browser tries to connect that SSL encrypted website.
Thenbrowser asks the web server to identify itself.
- For identification, the servers send SSL Certificate’s copy to the browser.
- Now the browser analyzes the certificate and verifies whether to trust it or not.
- If the browser trusts the certificate, it gives a message to the server
- After that, to start the SSL encrypted session, the server sends back a digitally signed acknowledgment to the browser.
- Now the Data shared between browser and server is being encrypted and HTTPS appears.
How to Enable HTTPS or How to make a Website HTTPS Encrypted?
Generate CSR and Private Key: Once you adopt an SSL certificate, the very next step is to generate CSR and private key. CSR (Certificate Signing Request) will be generated using CSR tool which will be available on Certificate Authority or on your Server manager. Fill out the correct information during CSR generation process. You will get CSR and Private-Key in encoded (cryptographic) format. Save the CSR and Private-Key at a safe location on your server or on a local drive.
Domain and Business Validation: After CSR and Private-Key generation, the certificate will ask the issuer to submit several business documents for verification. In the case of domain validation, the verification process will be completed by checking the domain registrar’s information via Email or by uploading File.
In the case of organization validated (OV), extended validation (EV) and code signing certificate option, the business document verification is mandatory. Here, the user needs to submit documents required by the certificate authority. After verification, if the documents meet the requirements of the CA, it will quickly approve the certificate.
Note: Documents required by CA might change from one authority to the other.
SSL Installation: Once the domain & business have been verified by CA, the SSL certificate is now ready to be installed on the server. The user must know how to Install SSL certificate on his/her server.
On the successful installation of the certificate on the server, the website becomes ready with HTTPS. Now secured connection is established when a visitor visits that SSL encrypted website.
