HTTP vs HTTPS
HTTP and HTTPS are protocols for transferring data on the web. The key difference: HTTPS is encrypted and secure, while HTTP is not.
The Core Difference
| Aspect | HTTP | HTTPS |
|---|---|---|
| Security | None | Encrypted (SSL/TLS) |
| Port | 80 | 443 |
| URL | http:// | https:// |
| Padlock | No | Yes 🔒 |
| SEO | Lower | Boosted |
Why HTTPS is Safer
HTTPS encrypts data between browser and server. Without it, anyone on the network can read passwords, payments, and personal data in plain text.
How HTTPS Works
- Browser requests a secure connection.
- Server provides an SSL certificate.
- They establish encrypted communication.
Why It Matters
- Protects sensitive data.
- Builds user trust (padlock icon).
- Required for modern web features.
- Improves SEO rankings.
