Certificate Utility Enhancements:

  • Split certificate chains (splitCertificateChain)
  • Extract the Common Name from certificates (extractCommonName, extractLeafCommonName)
  • Extract expiration dates from all certificates in a chain (extractAllExpirationDates)
  • Get the earliest expiration date in a chain (getEarliestExpirationDate) [1] [2]
• Updated getExpirationStatus to consider the earliest expiration date in a chain, ensuring accurate status reporting for bundled certificates.
• Added getCertificateChainExpirationDetails to provide detailed status, expiration, and CN information for each certificate in a chain, supporting the new UI features.
