❓ FAQs
What is an SSL certificate and why is it important?
An SSL certificate is a digital certificate that authenticates a website's identity and enables encrypted connections between web servers and browsers. It's crucial for protecting sensitive data, building user trust, improving SEO rankings, and meeting modern web security standards.
How often should I check my SSL certificate?
It's recommended to check your SSL certificate monthly, especially 30-60 days before expiration. Set up automated monitoring for critical websites to avoid unexpected certificate expiration that could cause security warnings or site downtime.
What's the difference between DV, OV, and EV certificates?
Domain Validated (DV) certificates verify domain ownership only. Organization Validated (OV) certificates verify both domain and organization identity. Extended Validation (EV) certificates provide the highest level of validation, including rigorous business verification and display the organization name in the browser.
What should I do if my SSL certificate is expired or invalid?
If your certificate is expired, contact your certificate authority or hosting provider immediately to renew it. For invalid certificates, check for configuration issues, ensure proper installation, and verify that all certificate chain components are correctly installed on your server.
Can I check SSL certificates for any website, not just my own?
Yes, this tool can check SSL certificates for any publicly accessible website. This is useful for competitive analysis, security research, or verifying the security status of websites you interact with regularly.
What does the encryption strength indicate?
Encryption strength refers to the key size and algorithm used to secure the connection. Higher bit encryption (like 256-bit) provides stronger security. Modern certificates typically use RSA 2048-bit or higher, or elliptic curve cryptography for optimal security and performance.
