The CMSG_MAIL_LIST_ENCRYPT_INFO structure contains encryption information for a mailing list recipient of enveloped data. The PFN_CMSG_EXPORT_MAIL_LIST function updates this structure.
The size, in bytes, of this structure.
A value that specifies the ordinal number of a recipient in the recipient list specified by the pContentEncryptInfo parameter to the PFN_CMSG_EXPORT_MAIL_LIST function.
A CRYPT_ALGORITHM_IDENTIFIER structure that specifies the algorithm used to encrypt the content encryption key. The CryptMsgOpenToEncode function uses the pszObjId member of the CRYPT_ALGORITHM_IDENTIFIER structure to get the address of the function used to export the key. The function can be installed by using a Cryptography API: Next Generation (CNG) object identifier (OID).
A CRYPT_DATA_BLOB structure that contains the encrypted session key.
A value that specifies what members have been updated, and whose memory allocation must be freed by using the CryptMsgOpenToEncode function.
| Value | Meaning |
|---|---|
|
The pszObjId member of the CRYPT_ALGORITHM_IDENTIFIER structure referred to by the KeyEncryptionAlgorithm member was updated. |
|
The Parameters pbData member of the CRYPT_ALGORITHM_IDENTIFIER structure referred to by the KeyEncryptionAlgorithm member was updated. |
When called with the dwMsgType parameter set to CMSG_ENVELOPED, the CryptMsgOpenToEncode function initializes the CMSG_MAIL_LIST_ENCRYPT_INFO structure from the CMSG_MAIL_LIST_RECIPIENT_ENCODE_INFO structure. The CryptMsgOpenToEncode function calls the PFN_CMSG_EXPORT_MAIL_LIST function to update the CMSG_MAIL_LIST_ENCRYPT_INFO structure. If the callback function cannot be found, the CryptMsgOpenToEncode function fills this structure with default key information from the CMSG_CONTENT_ENCRYPT_INFO structure.
The following members of the CMSG_MAIL_LIST_ENCRYPT_INFO structure can be updated by the callback function:
- EncryptedKey
- KeyEncryptionAlgorithm.pszObjId
- KeyEncryptionAlgorithm.Parameters
- dwFlags
The other members are read-only.
