CertificateStatus.EKU method

[CAPICOM is a 32-bit only component that is available for use in the following operating systems: Windows Server 2008, Windows Vista, and Windows XP. Instead, use the X509ChainStatus Structure in the System.Security.Cryptography.X509Certificates namespace.]

The EKU method returns the EKU object used to build the Chain object.

Syntax

CertificateStatus.EKU()

Parameters

This method has no parameters.

Return value

This method returns an EKU object that indicates the extended key usage setting of the certificate. The EKU setting establishes a certificate's valid use. Only a single EKU object can be set for each certificate.

Remarks

The CertificateStatus.ApplicationPolicies method provides the same functionality as this method but allows many settings to be specified instead of only one. If the OIDs collection returned by the ApplicationPolicies method contains one or more OID objects, the EKU object returned by this method is ignored. Use the ApplicationPolicies method instead of this method.
