HTTP transmits web exchanges without native cryptographic protection. HTTPS adds TLS to encrypt the connection and authenticate the server using a certificate.
In brief….HTTPS is essential, but does not guarantee that the site itself is reliable or free of vulnerabilities. It protects the connection between the browser and the server.
Solution A….
HTTP
HTTP transports requests and web responses to the network in plain language.
Key points…
- Current port 80
- Content legible or editable by a network intermediary
- To be reserved for the controlled surroundings or the Dedications
Solution B….
HTTPS
HTTPS encapsulates HTTP in a secure TLS connection.
Key points…
- Current port 443
- Confidentiality and integrity of the connection
- Certificate verified by the browser
Comparative table….
| Criterion…. | HTTP | HTTPS |
|---|---|---|
| Encryption | No | Yes with TLS |
| Server authentication | No | Yes by certificate |
| SEO and navigators | Not recommended for public site | Standard expected |
| Sensitive data | To be prohibited | Protected during transport |
Choose HTTP if…
You only have a local redirect controlled to HTTPS or perform a single isolated test.
Choose HTTPS if…
You publish any website or application that is accessible to users.
Key takeaways
HTTPS is essential, but does not guarantee that the site itself is reliable or free of vulnerabilities. It protects the connection between the browser and the server.
