CMSG_MAIL_LIST_RECIPIENT_INFO structure

The CMSG_MAIL_LIST_RECIPIENT_INFO structure contains information used for previously distributed symmetric key-encryption keys (KEK).

Syntax


typedef struct _CMSG_MAIL_LIST_RECIPIENT_INFO {
  DWORD                       dwVersion;
  CRYPT_DATA_BLOB             KeyId;
  CRYPT_ALGORITHM_IDENTIFIER  KeyEncryptionAlgorithm;
  CRYPT_DATA_BLOB             EncryptedKey;
  FILETIME                    Date;
  PCRYPT_ATTRIBUTE_TYPE_VALUE pOtherAttr;
} CMSG_MAIL_LIST_RECIPIENT_INFO, *PCMSG_MAIL_LIST_RECIPIENT_INFO;

Members

dwVersion

Indicates the version of the structure. This member is always four.

KeyId

A CRYPT_DATA_BLOB structure that identifies a symmetric key-encryption key previously distributed to the sender and one or more recipients.

KeyEncryptionAlgorithm

CRYPT_ALGORITHM_IDENTIFIER that identifies the key-encryption algorithm and any associated parameters used to encrypt the content encryption key.

EncryptedKey

A CRYPT_DATA_BLOB structure that contains the encrypted content encryption key.

Date

Optional. When present, this member specifies a single key-encryption key from a previously distributed set.

pOtherAttr

Optional pointer to a CRYPT_ATTRIBUTE_TYPE_VALUE structure containing additional information.

Requirements
