The CMSG_CTRL_DEL_SIGNER_UNAUTH_ATTR_PARA structure is used to delete an unauthenticated attribute of a signer of a signed message. This structure is passed to CryptMsgControl if the dwCrlType parameter is CMSG_CTRL_DEL_SIGNER_UNAUTH_ATTR.

Syntax

typedef struct _CMSG_CTRL_DEL_SIGNER_UNAUTH_ATTR_PARA {
  DWORD cbSize;
  DWORD dwSignerIndex;
  DWORD dwUnauthAttrIndex;
} CMSG_CTRL_DEL_SIGNER_UNAUTH_ATTR_PARA, *PCMSG_CTRL_DEL_SIGNER_UNAUTH_ATTR_PARA;
