The full form of HTTPS is “HyperText Transfer Protocol Secure.” It is a secure version of the standard HTTP protocol used to transmit data on the internet. “https” is used to transmit sensitive information, such as login credentials and financial data, over the internet in a way that is secure and encrypted. This helps to prevent data from being intercepted or compromised by third parties while it is in transit.
To establish a secure connection using “https,” a web server and client use a process called SSL/TLS (Secure Sockets Layer/Transport Layer Security) to exchange a series of keys and verify each other’s identity. Once the connection is established, data transmitted between the server and client is encrypted and secured, ensuring that it cannot be intercepted or read by anyone other than the intended recipient.

“https” is commonly used by online shopping sites, online banking platforms, and other websites that handle sensitive information. You can tell if a website is using “https” by looking for the padlock icon in the address bar of your web browser.

Functions of HTTPS
There are several key functions of “https” (HyperText Transfer Protocol Secure):
- Data encryption: “https” uses SSL/TLS (Secure Sockets Layer/Transport Layer Security) to encrypt data transmitted between a web server and client. This helps to protect sensitive information, such as login credentials and financial data, from being intercepted or compromised by third parties.
- Data integrity: “https” helps to ensure that data transmitted between a web server and client has not been tampered with or modified in any way. This helps to prevent data from being corrupted or altered during transmission.
- Identity verification: “https” uses a process called SSL/TLS certificate validation to verify the identity of the web server and client. This helps to ensure that users are communicating with the intended website, rather than a malicious imposter.
- Secure connection: “https” establishes a secure connection between a web server and client, protecting data transmitted between them from being intercepted or compromised by third parties.
- Trustworthiness: Websites that use “https” are typically considered more trustworthy and secure than those that do not. This is because “https” helps to protect sensitive information transmitted over the internet and ensures that users are communicating with the intended website.
How Does HTTPS Work?
“HTTPS” (HyperText Transfer Protocol Secure) is a secure version of the standard HTTP protocol used to transmit data over the internet. It is used to transmit sensitive information, such as login credentials and financial data, in a way that is secure and encrypted.
To establish a secure connection using HTTPS, a web server and client use a process called SSL/TLS (Secure Sockets Layer/Transport Layer Security) to exchange a series of keys and verify each other’s identity. This process involves the following steps:
- The client sends a request to the server to establish a secure connection.
- The server responds by sending a copy of its SSL/TLS certificate, which includes its public key.
- The client checks the certificate to verify the server’s identity. If the certificate is valid, the client generates a unique session key and encrypts it using the server’s public key.
- The encrypted session key is sent back to the server, along with a message authentication code (MAC) that is used to verify the integrity of the message.
- The server decrypts the session key using its private key and uses it to establish an encrypted connection with the client.
Once the connection is established, data transmitted between the server and client is encrypted and secured, ensuring that it cannot be intercepted or read by anyone other than the intended recipient. This helps to protect sensitive data transmitted over the internet.
Difference Between HTTP and HTTPS
HTTP (HyperText Transfer Protocol) is a standard protocol used to transmit data over the internet. It is not encrypted and does not provide any mechanisms for verifying the identity of the web server or client.
HTTPS (HyperText Transfer Protocol Secure) is a secure version of HTTP that uses encryption and identity verification to protect data transmitted over the internet. It uses SSL/TLS (Secure Sockets Layer/Transport Layer Security) to encrypt data and verify the identity of the web server and client. Websites that use HTTPS are generally considered more trustworthy and secure than those that use HTTP.
List of differences between HTTP & HTTPS:
| Feature | HTTP | HTTPS |
|---|---|---|
| Encryption | No | Yes (uses SSL/TLS) |
| Identity verification | No | Yes (uses SSL/TLS certificate validation) |
| Secure connection | No | Yes |
| Protocol Type | Application layer protocol | Transport layer protocol |
| Data Transmit Port Number | 80 | 443 |
| Trustworthiness | Low | High |
| Address bar | http:// | https:// |
| Web Page Loading Speed | Fast | Slow |
| Google Ranking Priority | Low | High |
