CMSG_CTRL_ADD_SIGNER_UNAUTH_ATTR_PARA structure (wincrypt.h)

The CMSG_CTRL_ADD_SIGNER_UNAUTH_ATTR_PARA 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;
