CERT_TRUST_STATUS structure

The CERT_TRUST_STATUS structure contains trust information about a certificate in a certificate chain, summary trust information about a simple chain of certificates, or summary information about an array of simple chains.

Syntax


typedef struct _CERT_TRUST_STATUS {
  DWORD dwErrorStatus;
  DWORD dwInfoStatus;
} CERT_TRUST_STATUS, *PCERT_TRUST_STATUS;

CERT_TRUST_HAS_NOT_SUPPORTED_NAME_CONSTRAINT
0x00001000

The certificate or one of the certificates in the certificate chain has a name constraints extension that contains unsupported fields. The minimum and maximum fields are not supported. Thus minimum must always be zero and maximum must always be absent. Only UPN is supported for an Other Name. The following alternative name choices are not supported:

  • X400 Address
  • EDI Party Name
  • Registered Id
CERT_TRUST_HAS_NOT_DEFINED_NAME_CONSTRAINT
0x00002000

The certificate or one of the certificates in the certificate chain has a name constraints extension and a name constraint is missing for one of the name choices in the end certificate.

CERT_TRUST_HAS_NOT_PERMITTED_NAME_CONSTRAINT
0x00004000

The certificate or one of the certificates in the certificate chain has a name constraints extension, and there is not a permitted name constraint for one of the name choices in the end certificate.

CERT_TRUST_HAS_EXCLUDED_NAME_CONSTRAINT
0x00008000

The certificate or one of the certificates in the certificate chain has a name constraints extension, and one of the name choices in the end certificate is explicitly excluded.

CERT_TRUST_IS_OFFLINE_REVOCATION
0x01000000

The revocation status of the certificate or one of the certificates in the certificate chain is either offline or stale.

CERT_TRUST_NO_ISSUANCE_CHAIN_POLICY
0x02000000

The end certificate does not have any resultant issuance policies, and one of the issuing certification authority certificates has a policy constraints extension requiring it.

CERT_TRUST_IS_EXPLICIT_DISTRUST
0x04000000

The certificate is explicitly distrusted.

Windows Vista and Windows Server 2008:  Support for this flag begins.

CERT_TRUST_HAS_NOT_SUPPORTED_CRITICAL_EXT
0x08000000

The certificate does not support a critical extension.

Windows Vista and Windows Server 2008:  Support for this flag begins.

CERT_TRUST_HAS_WEAK_SIGNATURE
0x00100000

The certificate has not been strong signed. Typically this indicates that the MD2 or MD5 hashing algorithms were used to create a hash of the certificate.

Windows 8 and Windows Server 2012:  Support for this flag begins.

 

The following codes are defined for chains only.

ValueMeaning
CERT_TRUST_IS_PARTIAL_CHAIN
0x00010000

The certificate chain is not complete.

CERT_TRUST_CTL_IS_NOT_TIME_VALID

A certificate trust list (CTL) used to create this chain was not time valid.

CERT_TRUST_CTL_IS_NOT_SIGNATURE_VALID
0x00040000

CERT_TRUST_IS_CA_TRUSTED
0x00004000

A non-self-signed intermediate CA certificate was found in the store pointed to by the hExclusiveRoot member of the CERT_CHAIN_ENGINE_CONFIG structure. The CA certificate is treated as a trust anchor for the certificate chain. This flag will only be set if the CERT_CHAIN_EXCLUSIVE_ENABLE_CA_FLAG value is set in the dwExclusiveFlags member of the CERT_CHAIN_ENGINE_CONFIG structure.

If this flag is set, the CERT_TRUST_IS_SELF_SIGNED and the CERT_TRUST_IS_PARTIAL_CHAINdwErrorStatus flags will not be set.
