◆ APPLE_IMG4_VERIFY

typedef EFI_STATUS(EFIAPI * APPLE_IMG4_VERIFY) (IN APPLE_IMG4_VERIFICATION_PROTOCOL *This, IN UINT32 ObjType, IN CONST VOID *ImageBuffer, IN UINTN ImageSize, IN UINT8 SbMode, IN CONST VOID *ManifestBuffer, IN UINTN ManifestSize, OUT UINT8 **HashDigest OPTIONAL, OUT UINTN *DigestSize OPTIONAL)

Verify the signature of ImageBuffer against Type of its IMG4 Manifest.

Parameters

[in]	This	The pointer to the current protocol instance.
[in]	ObjType	The IMG4 object type to validate against.
[in]	ImageBuffer	The buffer to validate.
[in]	ImageSize	The size, in bytes, of ImageBuffer.
[in]	SbMode	The requested IMG4 Secure Boot mode.
[in]	ManifestBuffer	The buffer of the IMG4 Manifest.
[in]	ManifestSize	The size, in bytes, of ManifestBuffer.
[out]	HashDigest	On output, a pointer to ImageBuffer's digest.
[out]	DigestSize	On output, the size, in bytes, of *HashDigest.

Return values

EFI_SUCCESS	ImageBuffer is correctly signed.
EFI_INVALID_PARAMETER	One or more required parameters are NULL.
EFI_OUT_OF_RESOURCES	Not enough resources are available.
EFI_SECURITY_VIOLATION	ImageBuffer's signature is invalid.
