CERT_INFO

The CERT_INFO structure stores information in a certificate.

typedef struct _CERT_INFO {

Members

dwVersion

The certificate's version number. Currently defined version numbers are shown in the following table.

Certificate version name	Value
CERT_V1	0
CERT_V2	1
CERT_V3	2

SerialNumber

The certificate's serial number. (Decoded as a multiple byte integer. SerialNumber.pbData[0] is the least significant byte. SerialNumber.pbData[SerialNumber.cbData - 1] is the most significant byte.)

For X509_ASN_ENCODING, leading 0x00 or 0xFF bytes are removed. See CertCompareIntegerBlob.

SignatureAlgorithm

A structure that contains the signature algorithm type and any associated additional parameters (encoded form).

Issuer

The certificate issuer's name (encoded form).

NotBefore

A date, before which the certificate is not valid. For X509_ASN_ENCODING, if the time is after 1950 and before 2050, it is UTC time encoded as a two-digit year precise to seconds. Otherwise, it is Generalized time encoded as a four-digit year precise to seconds.

NotAfter

A date, after which the certificate is not valid. For X509_ASN_ENCODING, if the time is after 1950 and before 2050, it is UTC time encoded as a two-digit year precise to seconds. Otherwise, it is Generalized time encoded as a four-digit year precise to seconds.

Subject

The certificate subject's name (encoded form).

SubjectPublicKeyInfo

A structure that contains the public key (encoded form) and its algorithm.

IssuerUniqueId

A special designation given to the issuer.

SubjectUniqueId

A special designation given to the subject.

cExtension

The number of elements in the array rgExtension.

rgExtension

An array of structures, each holding CERT_EXTENSION information about the certificate.
