When browsing the internet, you may have noticed that some websites start with “http://” while others begin with “https://”. Have you ever wondered what the difference is between the two? The disparity lies in the level of security they provide. Let’s explore the dissimilarities between HTTP and HTTPS.

HTTP, or Hypertext Transfer Protocol, is the foundation of web communication. It allows data to be transmitted between web browsers and servers. However, it lacks built-in security measures, making it vulnerable to attacks and unauthorized access. This is where HTTPS, or Hypertext Transfer Protocol Secure, comes into play.

HTTPS is an extension of HTTP that adds an extra layer of security through the use of SSL/TLS protocols. SSL (Secure Sockets Layer) and its successor, TLS (Transport Layer Security), establish an encrypted connection between the client and the server. This encryption ensures that any data exchanged between them remains confidential and cannot be intercepted by malicious actors.

The primary difference between HTTP and HTTPS lies in the presence of an SSL/TLS certificate. Websites using HTTPS have obtained and installed this certificate, which is issued by a trusted Certificate Authority (CA). The certificate verifies the authenticity of the website and enables secure communication.

To establish an HTTPS connection, the web server and browser perform a process called the SSL/TLS handshake. During this handshake, they exchange digital certificates, negotiate an encryption algorithm, and verify the authenticity of the certificates. Once the handshake is successful, a secure connection is established, and all data transmitted between the client and server is encrypted.

When you visit a website with HTTPS, you can trust that your interactions are secure. It protects sensitive information, such as login credentials, credit card details, and personal data, from being intercepted or tampered with by malicious individuals.

In summary, the key distinction between HTTP and HTTPS is the presence of encryption and security. HTTPS adds an extra layer of protection by encrypting data exchanged between the client and server, ensuring confidentiality and integrity. When browsing or engaging in online transactions, it is crucial to look for the padlock icon and “https://” in the URL to ensure your connection is secure.
