What is SSL and HTTPS

SSL stands for Secure Sockets Layer, which is a standard security technology used to establish an encrypted link between a web server and a web browser. SSL technology ensures that all data transferred between the web server and browser remains private and secure, protecting sensitive information such as passwords, credit card numbers, and personal information.

SSL works by using a cryptographic system that uses two keys to encrypt data: a public key and a private key. The public key is used to encrypt the data, and the private key is used to decrypt it. This creates a secure and encrypted connection between the web server and browser, preventing anyone from intercepting or reading the data.

In order to use SSL, a website must obtain an SSL certificate from a trusted Certificate Authority (CA). The certificate is installed on the web server, and it contains information such as the domain name, company name, and other identifying information. When a user visits a website with an SSL certificate, their web browser checks the certificate to ensure that it is valid and issued by a trusted CA. If the certificate is valid, the browser establishes a secure, encrypted connection with the web server.

Once the SSL connection is established, the user’s web browser will display a padlock icon in the address bar, indicating that the connection is secure. Some browsers may also display a green address bar or other indicators to show that the website is using SSL.

In addition to providing security for sensitive data, SSL is also important for SEO (Search Engine Optimization) purposes. Google and other search engines prioritize websites that use SSL, so having an SSL certificate can help to improve a website’s search engine ranking.

Overall, SSL is a critical technology for ensuring the security and privacy of website users, and it is increasingly becoming a standard practice for all websites, particularly those that handle sensitive data.
