  • HashAlgOID - OID of the hash algorithm, used to create IssuerNameHash and IssuerKeyHash
  • IssuerNameHash - hash of the IssuerName field of the certificate, being verified
  • IssuerKeyHash - hash of the public key of the certificate, which was used to sign the certificate being verified
  • CertificateSerial - serial of the certificate being verified
  • CertStatus - certificate status
  • Reason - reason of certificate revocation
  • RevocationTime - time when the certificate was revoked
  • ThisUpdate - time of the current status update
  • NextUpdate - time of the next status update
  • pHashAlgOID -
  • szHashAlgOID - the length of pcHashAlgOID.
  • pIssuerNameHash -
  • szIssuerNameHash - the length of pcIssuerNameHash.
  • pIssuerKeyHash -
  • szIssuerKeyHash - the length of pcIssuerKeyHash.
  • pCertificateSerial -
  • szCertificateSerial - the length of pcCertificateSerial.
