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_PUBLIC_KEY_INFO

This structure contains a public key and its algorithm.

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_LIST_INFO

This structure indicates a valid usage of a CTL.

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.

This structure is used to delete an unauthenticated attribute of a signer of a signed message.

CMSG_CTRL_KEY_AGREE_DECRYPT_PARA

This structure contains information about a key agreement recipient.

CMSG_CTRL_VERIFY_SIGNATURE_EX_PARA

This structure contains information that is used to verify a message signature. It contains the signer index and signer public key.
