Everything you want to know about SSL certificates and security.
SSL (Secure Sockets Layer) is a security protocol that encrypts the data exchanged between your website and its visitors. An SSL certificate verifies your site's identity and enables HTTPS connections.
Security: Data is encrypted and cannot be read by third parties.
Trust: Visitors see a padlock icon in their browser.
SEO: Google gives priority to HTTPS sites in its rankings.
Compliance: It is required for PCI DSS compliance when processing credit card payments.
When an SSL certificate expires, browsers show visitors a security warning. This can cause visitors to lose trust in your site and your SEO rankings to drop, so it is important to renew your certificate on time.
Key size (in bits) determines the strength of the encryption. According to modern standards:
2048 bit: The minimum recommended security level.
4096 bit: Higher security, but slower processing.
Keys smaller than 2048 bits are not considered secure.
