ICertServerPolicy::GetCertificateProperty method (certif.h)
The GetCertificateProperty method returns a named property from a certificate.
You must call ICertServerPolicy::SetContext prior to using this method.
Syntax
HRESULT GetCertificateProperty(
[in] const BSTR strPropertyName,
[in] LONG PropertyType,
[out] VARIANT *pvarPropertyValue
);
Parameters
[in] strPropertyName
Specifies the named property to retrieve. There is a stock set of certificate properties, referred to as the name properties, that are always valid and can be retrieved by calling this method. For information about these properties, see Name Properties. Other properties beside name properties can also be retrieved.
The certificate's DistinguishedName and RawName properties are accessible by ICertServerExit::GetCertificateProperty only after the policy module has finished processing the request and the certificate is issued. The issued certificate's DistinguishedName and RawName properties can also be read by an exit module by using ICertServerExit::GetCertificateProperty.
There are additional certificate properties that cannot be accessed by GetCertificateProperty. These properties are not set until after the policy module returns VR_INSTANT_OK and the certificate is issued. For a complete list of all the properties in an issued certificate, see GetCertificateProperty.
The following properties are unique to certificates and can be read by GetCertificateProperty.
| Certificate property | Meaning |
|---|---|
|
Internal request ID |
|
Certificate start validity date |
|
Certificate expiration date |
|
Subject key |
|
Subject key algorithm object ID (OID) |
|
Subject key algorithm parameters |
|
GeneralFlags in the enrollment request. This is a bitwise OR of values. The only value of interest should be the flag value of 0x00000400, which tells the CA not to persist the request in the database. If the CA is in databaseless mode (that is, for Windows Server 2008 R2 and later CAs, the CA's database has the DBFLAGS_ENABLEVOLATILEREQUESTS flag set), use certutil -getreg DbFlags and certutil -setreg DBFlags for configuring the CA in databaseless mode.

For renewal requests, returns the requester account name (for example, contoso\requester). |
The following properties apply to the certification authority.
| CA property | Meaning |
|---|---|
|
The type of certification authority. This can be one of the following values (defined in Certsrv.h):
|
|
The number of CA certificates. This value will be one plus the number of times that the CA has been renewed. For information about renewal, see Certification. |
|
The CA certificate state. This can be one of the following values:
|
|
The suffix for the CA certificate. The suffix is an empty string for CA certificates with an index of zero; otherwise, the suffix (in the form of "(nn)", where nn is the certificate index) is applied to all URLs that point to CA certificates stored in files or directory service objects. For non-LDAP URLs, the suffix typically appears before the ".crt" text. For LDAP URLs, the suffix is typically appended to the first 'CN=' in the full distinguished name.
This property name may be appended with '.#', where # represents a CA certificate index (or, in the case of the CRLSuffix property, a CRL index). For information about certificate and CRL indices, see Certification Authority Renewal. |
|
The certificate revocation list (CRL) index. Appending a certificate index to this property name allows you to retrieve the CRL index. The CRL index does not necessarily match the certificate index. For more information, see
Certification.
This property name may be appended with '.#', where # represents a CA certificate index (or, in the case of the CRLSuffix property, a CRL index). For information about certificate and CRL indices, see Certification Authority Renewal. |
|
The CRL state. This can be one of the following values:
|
|
The suffix for the CA CRL. The suffix is an empty string for CRLs with an index of zero; otherwise, the suffix (in the form of "(nn)", where nn is the CRL index) is applied to all URLs that point to CRLs stored in files or directory service objects. For non-LDAP URLs, the suffix typically appears before the .crl text. For LDAP URLs, the suffix typically is appended to the first 'CN=' in the full distinguished name.
This property name may be appended with '.#', where # represents a CA certificate index (or, in the case of the CRLSuffix property, a CRL index). For information about certificate and CRL indices, see Certification Authority Renewal. |
|
Indicates whether the CA uses a directory service. This can be either of the following values:
|
|
The DNS name of the server hosting the CA. |
|
The registry location available for use by the module. |
|
The CA certificate.
This property name may be appended with '.#', where # represents a CA certificate index (or, in the case of the CRLSuffix property, a CRL index). For information about certificate and CRL indices, see Certification Authority Renewal. |
|
The certificate revocation list (CRL) of the CA.
This property name may be appended with '.#', where # represents a CA certificate index (or, in the case of the CRLSuffix property, a CRL index). For information about certificate and CRL indices, see Certification Authority Renewal. |
|
Indicates whether the requester is authorized to request the certificate. This can be either of the following values:
|
|
The sanitized name for the CA. For information about sanitized CA names, see ICertConfig::GetConfig. |
|
The sanitized name for the CA, which is shortened and which contains a hash value to ensure uniqueness. |
[in] PropertyType
Specifies the property type. The type can be one of the following values.
| Type | Meaning |
|---|---|
|
Signed long data |
|
Date/time |
|
Binary data |
|
Unicode string data |
[out] pvarPropertyValue
A pointer to VARIANT that will contain the property value.
Return value
If the method succeeds, the method returns S_OK, and *pvarPropertyValue is set to the VARIANT that contains the requested property value.
If the method fails, it returns an HRESULT value that indicates the error. For a list of common error codes, see Common HRESULT Values.
