The main difference between HTTPS and HTTP is the secure connection established through Transport Layer Security (TLS). When using a secure connection, data transmitted over the internet remains confidential and cannot be intercepted by third parties. This is achieved through the use of cryptographic protocols such as SSL/TLS.
How HTTPS Ensures Security
Cryptography ensures confidentiality and integrity of data by encrypting it with a secret key. This prevents eavesdropping, tampering, or alteration of data in transit. Additionally, TLS provides authentication between the client (user's browser) and server, ensuring that only authorized devices can establish the secure connection.
Key Differences Between HTTPS and HTTP
The primary difference between HTTPS and HTTP is the presence of a secure socket layer (SSL). When using an SSL/TLS connection, data encryption occurs in real-time, making it more difficult for attackers to intercept or access sensitive information.
HTTPS vs HTTP: A Comparison Chart
| Protocol | HTTP | HTTPS |
|---|---|---|
| Insecure | Data transmitted is vulnerable to interception and eavesdropping | Critical security features: encryption, authentication, and confidentiality |
| Secure connection | Data remains confidential and cannot be intercepted | Critical security feature: secure socket layer (SSL) or transport layer security (TLS) |
