This structure is used to add an unauthenticated attribute to a signer of a signed message. This structure is passed to CryptMsgControl if the dwCtrlType parameter is set to CMSG_CTRL_ADD_SIGNER_UNAUTH_ATTR.

Syntax

typedef struct _CMSG_CTRL_ADD_SIGNER_UNAUTH_ATTR_PARA {
  DWORD cbSize;
  DWORD dwSignerIndex;
  CRYPT_DATA_BLOB BLOB;
} CMSG_CTRL_ADD_SIGNER_UNAUTH_ATTR_PARA, *PCMSG_CTRL_ADD_SIGNER_UNAUTH_ATTR_PARA;

Members
