Members

  • dwVersion
    Certificate's version number. The following table shows defined version numbers.
    Value Description
    CERT_V1 Version 1
    CERT_V2 Version 2
    CERT_V3 Version 3
  • SerialNumber
    BLOB (Cryptography) structure containing the certificate's serial number. The least significant byte is the zero byte of the pbData member of SerialNumber. The index for the last byte of pbData is one less than the value of the cbData member of SerialNumber. The most significant byte is the last byte of pbData. Leading 0x00 or 0xFF bytes are removed. For more information, see CertCompareIntegerBlob.
  • SignatureAlgorithm
    CRYPT_ALGORITHM_IDENTIFIER structure containing the signature algorithm type and encoded additional encryption parameters.
  • Issuer
    Certificate issuer's name in encoded form.
  • NotBefore
    Date and time before which the certificate is not valid. For dates between 1950 and 2049 inclusive, the date and time is encoded UTC-time in the form YYMMDDHHMMSS. This member uses a two-digit year and is precise to seconds. For dates before 1950 or after 2049, encoded generalized time is used. Encoded generalized time is in the form YYYYMMDDHHSSMMM, using a four-digit year, and is precise to milliseconds. Even though generalized time supports millisecond resolution, the NotBefore time is only precise to seconds.
  • NotAfter
    Date and time after which the certificate is not valid. For dates between 1950 and 2049 inclusive, the date and time is encoded UTC-time in the form YYMMDDHHMMSS. This member uses a two-digit year and is precise to seconds. For dates before 1950 or after 2049, encoded generalized time is used. Encoded generalized time is in the form YYYYMMDDHHSSMMM, using a four-digit year, and is precise to milliseconds. Even though generalized time supports millisecond resolution, the NotAfter time is only precise to seconds.
  • Subject
    Certificate subject's encoded name.
  • SubjectPublicKeyInfo
    BLOB structure containing the encoded public key and its algorithm.
  • IssuerUniqueId
    BLOB structure containing a unique identifier of the issuer.
  • SubjectUniqueId
    BLOB structure containing a unique identifier of the subject.
  • cExtension
    Number of elements in the rgExtension array.
  • rgExtension
    Array of pointers to CERT_EXTENSION structures, each containing extension information about the certificate.

Requirements

OS Versions: Windows CE 3.0 and later.
