In this article, we will learn How SSL make HTTP Secure. SSL stands for Secure Socket Layer. SSL has been succeeded by TLS (Transport Layer Security). Even though TLS has replaced SSL, people still commonly use the term “SSL” to talk about secure communication on the web.
HTTP is the standard protocol used for transmitting data between a web browser and a website’s server. However, the data exchanged via HTTP is not encrypted, which means that any information sent between your browser and the server can potentially be intercepted and read by malicious actors. This lack of encryption makes HTTP connections vulnerable to eavesdropping and data breaches. Since HTTP is not a secure protocol, and transmits data in clear text, to address this, in this article we will discuss How SSL make HTTP secure.
How SSL make HTTP Secure
SSL (Secure Sockets Layer) enhances the security of HTTP by employing encryption, authentication, and data integrity mechanisms. SSL(TLS) add an additional layer to HTTP to make it secure. Thus, HTTP protocol with an additional layer of SSL/TLS encryption on top of it called HTTPS (Hypertext Transfer Protocol Secure).
When a user connects to a website using HTTPS (HTTP Secure), SSL(TLS) establishes a secure and encrypted connection between the user’s browser and the web server. A session key is generated and used for secure encryption.
SSL(TLS) also offers authentication through digital certificates. Websites present these certificates to prove their identity, and the user’s browser verifies their authenticity. This prevents attackers from impersonating legitimate websites and helps users trust that they are interacting with the intended site.
Both the client and server exchange encrypted messages using the symmetric session key, Once the session is established. The feature of terminating the session on detection of unexpected messages and generating various security alerts during the session are salient features of HTTPS.
Furthermore, SSL(TLS) ensures data integrity. Through cryptographic techniques like hash functions and digital signatures, the protocol confirms that the data hasn’t been altered during transit. This guards against data manipulation or tampering by hackers.
By combining encryption, authentication, and data integrity, SSL(TLS) effectively shields sensitive information such as passwords, credit card details, and personal data from unauthorized access. This secure communication is vital for protecting user privacy and preventing cyberattacks. Like eavesdropping and data breaches, ultimately establishing a safer online experience.
