3/28/2014

This structure provides parameters for finding issuer certificates used to build a certificate chain.

Syntax

typedef struct _CERT_USAGE_MATCH {
  DWORD dwType;
  CERT_ENHKEY_USAGE Usage;
} CERT_USAGE_MATCH, *PCERT_USAGE_MATCH;

Members

• dwType
  Type of issuer matching to be done. In AND logic, the certificate must meet all criteria. In OR logic, the certificate must meet at least one of the criteria. The following table shows defined codes that determine the logic used in the match.

  Code	Description
  USAGE_MATCH_TYPE_AND	AND logic
  USAGE_MATCH_TYPE_OR	OR logic

  The default usage match logic is USAGE_MATCH_TYPE_AND.

• Usage
  CERT_ENHKEY_USAGE structure, which is the same as a CTL_USAGE structure, that includes an array of certificate OIDs that a certificate must match in order to be valid.
