Defines a entry in the array of images that an enclave can import.

Syntax

typedef struct _IMAGE_ENCLAVE_IMPORT {
  DWORD MatchType;
  DWORD MinimumSecurityVersion;
  BYTE  UniqueOrAuthorID[IMAGE_ENCLAVE_LONG_ID_LENGTH];
  BYTE  FamilyID[IMAGE_ENCLAVE_SHORT_ID_LENGTH];
  BYTE  ImageID[IMAGE_ENCLAVE_SHORT_ID_LENGTH];
  DWORD ImportName;
  DWORD Reserved;
} IMAGE_ENCLAVE_IMPORT, *PIMAGE_ENCLAVE_IMPORT;

Members

MatchType

The type of identifier of the image that must match the value in the import record.

Value	Meaning
IMAGE_ENCLAVE_IMPORT_MATCH_NONE 0x00000000	None of the identifiers of the image need to match the value in the import record.
IMAGE_ENCLAVE_IMPORT_MATCH_UNIQUE_ID 0x00000001	The value of the enclave unique identifier of the image must match the value in the import record. Otherwise, loading of the image fails.
IMAGE_ENCLAVE_IMPORT_MATCH_AUTHOR_ID 0x00000002	The value of the enclave author identifier of the image must match the value in the import record. Otherwise, loading of the image fails. If this flag is set and the import record indicates an author identifier of all zeros, the imported image must be part of the Windows installation.
IMAGE_ENCLAVE_IMPORT_MATCH_FAMILY_ID 0x00000003	The value of the enclave family identifier of the image must match the value in the import record. Otherwise, loading of the image fails.
IMAGE_ENCLAVE_IMPORT_MATCH_IMAGE_ID 0x00000004	The value of the enclave image identifier of the image must match the value in the import record. Otherwise, loading of the image fails.

MinimumSecurityVersion

The minimum enclave security version that each image must have for the image to be imported successfully. The image is rejected unless its enclave security version is equal to or greater than the minimum value in the import record. Set the value in the import record to zero to turn off the security version check.

UniqueOrAuthorID[IMAGE_ENCLAVE_LONG_ID_LENGTH]

The unique identifier of the primary module for the enclave, if the MatchType member is IMAGE_ENCLAVE_IMPORT_MATCH_UNIQUE_ID. Otherwise, the author identifier of the primary module for the enclave..

FamilyID[IMAGE_ENCLAVE_SHORT_ID_LENGTH]

The family identifier of the primary module for the enclave.

ImageID[IMAGE_ENCLAVE_SHORT_ID_LENGTH]

The image identifier of the primary module for the enclave.

ImportName

The relative virtual address of a NULL-terminated string that contains the same value found in the import directory for the image.

Reserved

Reserved.
