What you will learn in this guide:
- Identify safe sites in seconds

- Avoid dangerous downloads that can ruin your device
- Protect your privacy from trackers and spies
- Browse safely on public Wi-Fi without risks
HTTPS and SSL/TLS Certificates
HTTPS (Hypertext Transfer Protocol Secure) encrypts all communication between your browser and the website. Without HTTPS, your passwords, bank details, and messages travel in plain text that anyone can intercept.
What is an SSL/TLS Certificate?
SSL/TLS certificates are digital documents that verify the identity of a website and enable encrypted connection. When you see the padlock in your browser, it means the site has a valid certificate.
Certificate Types
| Type | Validation | Visual Indicator | Recommended For |
|---|---|---|---|
| DV (Domain Validation) | Domain only | Basic padlock | Blogs, informational sites |
| OV (Organization Validation) | Domain + Company | Padlock + Company name | Businesses, e-commerce |
| EV (Extended Validation) | Full validation | Green bar + Company name | Banks, financial sites |
How to Verify a Certificate
Click on the padlock
In the address bar, next to the URL, you will see a padlock icon. Click on it.
Select "Certificate"
In the dropdown menu, look for the "Certificate" option (valid).
Verify these details
- Issued to: Must match exactly the domain you are visiting
- Issued by: Recognized Certificate Authority (Let's Encrypt, DigiCert, etc.)
- Valid from/to: Current dates, not expired
- Algorithm: RSA 2048 bits or higher, or ECDSA
Certificate Warning Signs
- "Not Secure" in the address bar
- Browser warning: "Your connection is not private"
- Name mismatch: Certificate for another domain
- Expired certificate: Beyond expiration date
- Unknown authority: Not issued by recognized CA
NEVER ignore these warnings on sites where you enter sensitive data.
