RECIPIENT_INFO Struct Reference

Holds message recipient information associated with a single recipient of a CMS message (supported) or a PKI message (deprecated).

The subordinate KEY_TRANSPORT_INFO structure is used to determine or obtain the key used to encrypt an internal content encryption key.

In a CMS message, this structure holds information about a single recipient of a CMS message.
This structure is used by C_ReadEnvelopedDataMsg(), C_WriteEnvelopedDataMsg(), C_AddRecipientToList(), C_AddUniqueRecipientToList(), C_InsertRecipientInList(), C_FreeRecipientEntry() and C_FreeRecipientInfo().
In a PKI message, the PKI_RECIPIENT structure uses this structure to hold information about a single recipient of a PKI message.
However, the use of the PKI_RECIPIENT structure is deprecated in Cert-C 2.0. Use the PKI_RECIPIENT_INFO structure (and the related C_SetPKIMsgRecipient() and C_GetPKIMsgRecipient() functions) instead.

Samples:: cms.c, datamsg.c, and p7stream.c.
