# HTTP vs HTTPS

## Overview

- **Summary:** HTTP transfers web pages; HTTPS adds SSL/TLS encryption. Why HTTPS is the default and how to migrate safely.

## Article

**HTTP** is the basic protocol for transferring web pages. **HTTPS** is HTTP over [SSL/TLS](/en/hosting-wiki/ssl-tls) — data between browser and server is encrypted in transit. Modern browsers show a padlock for HTTPS and often label HTTP as “Not Secure.”

For public sites today, HTTPS is effectively the default: user trust, login forms, payments, SEO, and many browser features expect it. HTTP may still appear for certificate challenges or redirects, but primary content should be served over HTTPS.

## A Simple Analogy

HTTP is like mailing an open postcard. HTTPS is like mailing a letter inside a vault only the real endpoints can open. The message can be identical; exposure on the road is not — especially on cafe Wi-Fi or shared networks.

## What HTTPS Changes

- Encryption in transit (harder to snoop)  
- Integrity (mid-path tampering is easier to detect)  
- Server identity via certificates (for example [Let’s Encrypt](/en/hosting-wiki/lets-encrypt))  
- Requirements for some browser APIs in a secure context  
- A friendlier search ranking signal than plain HTTP  

HTTPS does **not** automatically make application code immune to SQL injection, XSS, or outdated plugins. App security remains a separate job.

## HTTP → HTTPS Migration Checklist

1. Install a valid certificate on every hostname you use  
2. Force 301 redirects from `http://` to `https://` via [.htaccess](/en/hosting-wiki/htaccess) or the panel  
3. Update canonical URLs in the CMS and internal links  
4. Clean mixed content (assets still on `http://`)  
5. Refresh sitemaps and watch Search Console  

## What to Watch For

- Expired certificates trigger scary browser warnings  
- Cover both `www` and apex when both are active  
- Behind a CDN, align origin SSL mode  
- HSTS helps after HTTPS is stable on every path  

## FAQ

<Accordion>
  <AccordionItem title="Is plain HTTP still acceptable?">
    Technically possible, but poor for trust and modern features. Logins and forms should be HTTPS.
  </AccordionItem>
  <AccordionItem title="Does HTTPS slow the site?">
    Modern overhead is tiny; security and trust benefits are far larger.
  </AccordionItem>
  <AccordionItem title="Certificate is live but still Not Secure?">
    Usually mixed content: images, fonts, or scripts still loading over http.
  </AccordionItem>
  <AccordionItem title="Do I need paid SSL?">
    For most sites, Let’s Encrypt is enough. See the SSL/TLS and Let’s Encrypt articles.
