🔒 SSL CERTIFICATE FACTS

Essential cryptographic facts every site administrator should know:

  • Max 398-Day Validity: Since September 2020, major web browsers enforce a strict 398-day limit on public SSL/TLS certificates. Certificates issued for longer periods will be rejected by browsers.
  • Encryption vs. Identity: DV (Domain Validated) certificates encrypt data, but OV (Organization) and EV (Extended) certificates also verify the legal identity of the business.
  • Chain of Trust: A valid certificate relies on a full chain—your leaf certificate must link to an Intermediate CA, which traces back to a trusted Root CA in browser trust stores.
  • Certificate Transparency (CT): Modern TLS certificates are logged into publicly searchable CT logs (like crt.sh) at issuance to prevent CA misissuance and undetected phishing setups.
  • SEO & Security Impact: Google ranks HTTPS-enabled websites higher, while unencrypted HTTP sites trigger explicit "Not Secure" warnings to site visitors.
