What is an SSL Certificate?
An SSL (Secure Sockets Layer) certificate, now technically known as a TLS (Transport Layer Security) certificate, is a digital file that authenticates a website's identity and enables an encrypted connection.
When a website uses an SSL certificate, its URL will begin with https:// instead of http://, indicating that traffic between the user's browser and the web server is secure.
Why is SSL Important?
- Data Protection: Encrypts sensitive information like passwords, credit card numbers, and personal data.
- Trust: Browsers display a padlock icon or warn users if a site is "Not Secure," significantly impacting user trust.
- SEO Ranking: Search engines like Google use HTTPS as a ranking signal, penalizing non-secure websites.
- Compliance: Required for PCI-DSS compliance and many data protection regulations like GDPR.
