HTTPS vs HTTP: Key Differences
What is the difference between HTTP and HTTPS? HTTP, or HyperText Transfer Protocol, forms the basis for data communication on the web, yet it transmits data in plain text. This lack of encryption makes HTTP vulnerable to interception by malicious parties, posing a significant risk to data security. Without encryption, sensitive information such as passwords and credit card numbers can be easily accessed by unauthorised individuals during transmission.
HTTPS, which stands for HyperText Transfer Protocol Secure, addresses these security concerns by adding an encryption layer via SSL/TLS certificates. By encrypting data, HTTPS ensures that information sent between a user’s browser and a website’s server remains confidential and protected from interception. This process not only secures data but also authenticates websites, verifying that users are connecting to legitimate sites rather than imposter ones. The use of port 443, as opposed to HTTP’s port 80, further distinguishes HTTPS by facilitating secure connections.
Using HTTPS over HTTP has significant implications for user trust and data safety. Websites employing HTTPS are more likely to be trusted by users, as indicated by the padlock icon displayed in the address bar. This trust can enhance user experience, particularly for e-commerce sites handling sensitive transactions. In contrast, HTTP sites may deter users due to perceived security risks, potentially affecting a website’s reputation and user engagement.

How HTTPS Works: The Process Behind the Protocol
How does HTTPS work? At its core, HTTPS combines HTTP with SSL/TLS protocols to secure data transmission. The precision answer is that HTTPS encrypts data exchanged between a user’s browser and a website’s server, protecting it from interception. This encryption is crucial because it ensures that sensitive information, such as login credentials and payment details, remains confidential and inaccessible to unauthorised entities. SSL (Secure Socket Layer) and its successor TLS (Transport Layer Security) are the protocols responsible for this encryption. They provide both data integrity and authentication, verifying that users connect to legitimate websites. HTTPS connections typically operate on port 443, distinguishing them from HTTP’s use of port 80.
The process of establishing an HTTPS connection involves a series of steps known as the SSL handshake. This procedure enables the secure exchange of encryption keys, facilitating a protected session between the browser and server. During the handshake, digital certificates are exchanged to authenticate the server’s identity. This authentication prevents connections to fraudulent websites, thus enhancing user trust and data safety.
SSL Handshake Process
The SSL handshake is a critical component of HTTPS, involving multiple steps to establish a secure session. The steps are as follows:
- Browser requests a secure connection: The process begins when a user’s browser requests a secure connection to a website.
- Server responds with its SSL certificate: The server sends its SSL certificate, which contains its public key, to the browser.
- Browser verifies the certificate’s authenticity: The browser checks the SSL certificate against trusted certificate authorities to ensure its legitimacy.
- Encryption keys are exchanged: Once verified, the browser and server exchange encryption keys to establish a secure session.
- Secure connection is established: With the keys in place, a secure connection is established, allowing encrypted data transmission between the browser and server.
Benefits of HTTPS for Websites
What are the benefits of HTTPS? HTTPS enhances data privacy, boosts SEO rankings, and builds user trust. By encrypting data, HTTPS ensures secure communication between a user’s browser and a website’s server, protecting sensitive information from interception. This security measure is crucial for maintaining user confidence, as it verifies the authenticity of websites and guards against malicious attacks. In terms of SEO, Google and other search engines favour websites using HTTPS, potentially improving their visibility and ranking in search results. This preferential treatment is due to the increased security and reliability that HTTPS provides, which aligns with search engines’ goals of delivering safe and trustworthy content to users.
Why is HTTPS essential for e-commerce and other online transactions? HTTPS is critical for e-commerce sites as it protects customer payment information, prevents data breaches, and enhances site credibility. E-commerce transactions often involve sensitive data, such as credit card numbers and personal details, making security paramount. HTTPS encryption ensures that this information remains confidential during transmission, reducing the risk of fraud and identity theft. Additionally, the presence of HTTPS can significantly boost a website’s credibility, as customers are more likely to trust and engage with sites displaying the secure padlock icon. Furthermore, HTTPS helps e-commerce sites comply with security regulations, which often mandate secure data handling practices to protect consumer information.

SSL/TLS certificates are issued by trusted certificate authorities (CAs), which verify the authenticity of a website, thereby enhancing user trust and protecting sensitive information from interception. Without this certification, data transmitted over the internet remains vulnerable to malicious attacks.
How is HTTPS configured and maintained on a web server? Configuring and maintaining HTTPS involves several technical steps. Once an SSL/TLS certificate is obtained and installed, server settings must be adjusted to support secure connections. This involves configuring the server to use port 443 for HTTPS traffic and ensuring that all website elements are served securely. Additionally, setting up automatic HTTPS redirects from HTTP ensures that users are always directed to the secure version of the site. This not only enhances security but also optimises the user experience by maintaining consistency in secure connections.
- Select a trusted certificate authority
- Purchase an SSL/TLS certificate
- Install the certificate on the server
