❓ Frequently Asked Questions
What is an SSL certificate?
SSL (Secure Sockets Layer) certificates encrypt data between browsers and servers. They verify website identity and enable HTTPS, shown by the padlock icon in browsers.
How do I know if my SSL is valid?
A valid SSL certificate must be issued by a trusted authority, match the domain name, and not be expired. This tool checks all these factors automatically.
What happens when SSL expires?
Browsers show security warnings, blocking most visitors. Search rankings may drop. Renew certificates before expiration to avoid issues.
What's a good encryption strength?
Modern SSL certificates should use 2048-bit or 4096-bit RSA keys. Anything less than 2048-bit is considered weak and outdated.
Do I need SSL for my website?
Yes! SSL is essential for all websites. It's required for SEO, builds trust, and protects user data. Most hosts offer free SSL through Let's Encrypt.
