Certificate Status

Certificate Status indicates the current state of an SSL certificate's validity and usability. The status can be 'Valid' (certificate is currently valid and trusted), 'Expired' (certificate has passed its expiration date), 'Expiring Soon' (certificate will expire within a defined warning period, typically 30 days), 'Revoked' (certificate has been invalidated by the CA before its expiration date), or 'Invalid' (certificate has issues such as hostname mismatch, untrusted issuer, or malformed data). Understanding certificate status is crucial for maintaining website security and user trust. Valid certificates display a padlock icon in browsers, while invalid certificates trigger security warnings that can deter visitors. Certificate monitoring systems continuously check status to alert administrators before certificates expire, ensuring uninterrupted secure communications. The status is determined by checking the certificate's validity period, revocation status through CRL or OCSP, and proper certificate chain validation.
