CERT_POLICY_ID	This structure contains a list of certificate policies that the certificate expressly supports, together with optional qualifier information pertaining to these policies.
CERT_POLICY_INFO	This structure contains an object identifier specifying a policy and an optional array of policy qualifiers.
CERT_POLICY_QUALIFIER_INFO	This structure contains an object identifier specifying the qualifier and qualifier-specific supplemental information.
CERT_PRIVATE_KEY_VALIDITY	This structure indicates a valid time span for the private key corresponding to a certificate's public key.

CERT_RDN	This structure contains a relative distinguished name (RDN) consisting of an array of CERT_RDN_ATTR structures.
CERT_RDN_ATTR	This structure contains a single attribute of a relative distinguished name (RDN).
CERT_REQUEST_INFO	This structure contains information for a certificate request.
CERT_SIGNED_CONTENT_INFO	This structure contains encoded content to be signed and a BLOB (Cryptography) structure to hold the signature.
CERT_SIMPLE_CHAIN	This structure contains an array of chain elements and a summary trust status for the chain that the array represents.
CERT_SYSTEM_STORE_INFO	This structure contains information used by functions that work with system stores.
CERT_SYSTEM_STORE_RELOCATE_PARA	This structure contains data to be passed to the CertOpenStore function when that function's dwFlags parameter is set to CERT_SYSTEM_STORE_RELOCATE_FLAG.

CERT_TRUST_STATUS	This 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.
CERT_USAGE_MATCH	This structure provides parameters for finding issuer certificates used to build a certificate chain.
CMSG_CMS_RECIPIENT_INFO	This structure is used with the CryptMsgGetParam function to get information about a key transport, key agreement, or mail list envelope message recipient.
CMSG_CMS_SIGNER_INFO	This structure contains the content of the defined SignerInfo in signed or in signed and enveloped messages.
