  • Article

[The CRYPT_PROVIDER_CERT structure is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions.]

The CRYPT_PROVIDER_CERT structure provides information about a provider certificate.

Syntax

typedef struct _CRYPT_PROVIDER_CERT {
  DWORD               cbStruct;
  PCCERT_CONTEXT      pCert;
  BOOL                fCommercial;
  BOOL                fTrustedRoot;
  BOOL                fSelfSigned;
  BOOL                fTestCert;
  DWORD               dwRevokedReason;
  DWORD               dwConfidence;
  DWORD               dwError;
  CTL_CONTEXT         *pTrustListContext;
  BOOL                fTrustListSignerCert;
  PCCTL_CONTEXT       pCtlContext;
  DWORD               dwCtlError;
  BOOL                fIsCyclic;
  PCERT_CHAIN_ELEMENT pChainElement;
} CRYPT_PROVIDER_CERT, *PCRYPT_PROVIDER_CERT;

Members

cbStruct

The size, in bytes, of this structure.

pCert

A pointer to the certificate context.

fCommercial

Boolean value that indicates whether the certificate is a commercial certificate.

fTrustedRoot

Boolean value that indicates whether the certificate is a trusted root certificate.

fSelfSigned

Boolean value that indicates whether the certificate is self-signed.

fTestCert

Boolean value that indicates whether the certificate is a test certificate.

dwRevokedReason

Value that specifies the revocation reason, if applicable.

dwConfidence

Bitwise combination of zero or more of the following confidence values.

Value Meaning
CERT_CONFIDENCE_SIG
0x10000000
 The signature of the certificate is valid.
CERT_CONFIDENCE_TIME
0x01000000
 The time of the certificate issuer is valid.
CERT_CONFIDENCE_TIMENEST
0x00100000
 The time of the certificate is valid.
CERT_CONFIDENCE_AUTHIDEXT
0x00010000
 The authority ID extension is valid.
CERT_CONFIDENCE_HYGIENE
0x00001000
 At a minimum, the signature of the certificate and authority ID extension are valid.
CERT_CONFIDENCE_HIGHEST
0x11111000
 Combination of all of the other confidence values.

dwError

A pointer to a DWORD variable that contains the error value for this certificate, if applicable.

pTrustListContext

A pointer to the CTL_CONTEXT that represents the certificate trust list (CTL).

fTrustListSignerCert

Boolean value that specifies whether the certificate is a trust list signer certificate.

pCtlContext

A pointer to the CTL_CONTEXT that represents a CTL that contains a self-signed certificate, if applicable.

dwCtlError

A pointer to a DWORD variable that contains the error value for a CTL that contains a self-signed certificate, if applicable.

fIsCyclic

Boolean value that indicates whether the certificate trust is cyclical.

pChainElement

A pointer to the CERT_CHAIN_ELEMENT that represents the status of the certificate within a chain.
