What is the difference between HTTPS and HTTP?

Last Updated Jun 9, 2024

HTTP (HyperText Transfer Protocol) is the foundational protocol used for transmitting data over the internet, primarily for web pages. HTTPS (HyperText Transfer Protocol Secure) enhances HTTP by adding a layer of security through SSL/TLS encryption, ensuring that data exchanged between the user's browser and the website remains confidential and integral. This encryption helps protect sensitive information, such as passwords and payment details, from interception during transmission. HTTPS also provides authentication, signaling users that they are communicating with a legitimate server rather than an imposter. Websites utilizing HTTPS are generally ranked higher by search engines and display a padlock symbol, indicating a secure connection.

Protocol Type

HTTP (Hypertext Transfer Protocol) is an application layer protocol used for transmitting data over the internet, facilitating communication between web browsers and servers. In contrast, HTTPS (HTTP Secure) incorporates an additional layer of security by using SSL/TLS (Secure Sockets Layer/Transport Layer Security) encryption, protecting the integrity and confidentiality of data during transmission. This means that information exchanged over HTTPS is significantly more secure, safeguarding it from eavesdropping and man-in-the-middle attacks. When you visit a website using HTTPS, you can trust that your data, such as passwords and payment details, is being transmitted securely.

Security Encryption

HTTPS (HyperText Transfer Protocol Secure) utilizes Transport Layer Security (TLS) to enhance security, ensuring encrypted communication between your browser and the server. In contrast, HTTP (HyperText Transfer Protocol) transmits data in plaintext, making it vulnerable to interception and attacks such as man-in-the-middle. With HTTPS, your sensitive information--like passwords and credit card numbers--is securely encrypted, protecting it from eavesdroppers. Transitioning to HTTPS is crucial for maintaining user trust and safeguarding data integrity on your website.

Data Integrity

HTTP (Hypertext Transfer Protocol) transmits data in plaintext, making it vulnerable to interception and tampering by malicious entities. In contrast, HTTPS (Hypertext Transfer Protocol Secure) encrypts data using SSL/TLS protocols, ensuring that the information exchanged between your browser and the server remains confidential and tamper-proof. This encryption not only protects sensitive data, such as passwords and personal information, but also assures user authenticity through digital certificates. By choosing HTTPS, you enhance data integrity and establish a secure connection, minimizing the risk of data breaches and unauthorized access.

Performance Speed

The performance speed difference between HTTPS and HTTP primarily stems from encryption overhead. HTTPS, which uses SSL/TLS protocols to secure data transmission, introduces a slight delay due to the time taken for the handshake and encryption processes. However, advancements like HTTP/2 and QUIC have significantly optimized HTTPS performance, often making it as fast or even faster than HTTP in many scenarios. For your website, switching to HTTPS can enhance security and improve user trust, balancing the initial speed overhead with long-term benefits.

SSL/TLS Certificate

SSL/TLS certificates are pivotal in securing online communications, distinguishing HTTPS from HTTP. When a website uses HTTPS, it establishes an encrypted connection between your browser and the server, ensuring that sensitive data remains confidential during transmission. In contrast, HTTP does not provide this encryption, leaving information vulnerable to interception. By obtaining an SSL/TLS certificate, you enhance your website's security, boost user trust, and improve search engine rankings, as most modern browsers flag unsecured HTTP sites.

Default Port

HTTP typically operates over port 80, while HTTPS, which adds a layer of security through SSL/TLS encryption, uses port 443. This distinction is crucial as it affects how web traffic is routed and monitored. By choosing HTTPS, you ensure that data exchanged between your browser and the server is encrypted, protecting it from eavesdropping and tampering. Understanding the difference in ports helps you configure firewalls and servers effectively for secure communication.

Trust Indicator

HTTPS (HyperText Transfer Protocol Secure) encrypts data exchanged between your browser and the website, ensuring that sensitive information like passwords and credit card numbers remain confidential. In contrast, HTTP (HyperText Transfer Protocol) transmits data in plain text, making it susceptible to interception and tampering by malicious actors. As a result, websites using HTTPS often display a padlock icon in the address bar, signaling to users that their connection is secure. Choosing HTTPS over HTTP not only protects your data but also enhances your site's credibility and ranking in search engines.

Cost/Setup Complexity

The setup complexity for HTTPS is generally higher than that of HTTP due to the requirement of obtaining and installing an SSL/TLS certificate. This certificate validates your website's identity and encrypts data transmitted between the server and users, enhancing security. Cost-wise, while HTTP is free and requires no certificates, HTTPS incurs costs for SSL/TLS certificates, which can vary significantly based on the issuing authority. However, investing in HTTPS not only improves security but also boosts search engine rankings and user trust in your website.

SEO Ranking

HTTPS (Hypertext Transfer Protocol Secure) enhances website security by encrypting data exchanged between your browser and the server, significantly boosting SEO rankings. Google prioritizes HTTPS sites over HTTP (Hypertext Transfer Protocol) ones, as secure connections improve user trust and enhance overall site credibility. Websites using HTTPS can also benefit from better performance metrics, which are crucial for search engine algorithms that assess page load speed and user experience. Transitioning to HTTPS not only safeguards your visitors' data but also contributes positively to your website's visibility in search engine results pages.

Usage and Benefit

HTTP, or Hypertext Transfer Protocol, is the foundational protocol for transferring data on the web, allowing users to access websites. However, HTTPS, or Hypertext Transfer Protocol Secure, enhances this standard by encrypting data exchanged between the browser and server, ensuring security and privacy for users. Using HTTPS is crucial for protecting sensitive information, such as login credentials and personal data, from eavesdropping and man-in-the-middle attacks. You can benefit from increased search engine rankings and user trust when your website employs HTTPS, making it essential for modern web practices.
