Difference Between HTTP and HTTPS | ||
Feature | HTTP | HTTPS |
Full Form | Hypertext Transfer Protocol | Hypertext Transfer Protocol Secure |
Data Security | No encryption, data is plain text | Data is encrypted for secure transmission |
Protocol Layer | Application layer | Application layer |
Security Layer | No security layer | Uses TLS/SSL for data encryption |
URL | Begins with "http://" | Begins with "https://" |
Port | Uses port 80 | Uses port 443 |
Data Integrity | No data integrity check | Ensures data integrity through encryption |
Security | Less secure, vulnerable to interception and attacks | More secure, protects against data interception and attacks |
Use Cases | Suitable for general browsing and non-sensitive information | Essential for transmitting sensitive data, e.g., financial transactions, login credentials |
Indicators | Not visually marked in the browser | Visually marked with a padlock or "Secure" label in the browser |
Performance | Generally faster due to no encryption overhead | Slightly slower due to encryption and decryption processes |
Adoption | Widespread and commonly used | Increasingly adopted for better security |
