◆ AeadAesGcmDecrypt()

BOOLEAN EFIAPI AeadAesGcmDecrypt	(	IN CONST UINT8 *	Key,
		IN UINTN	KeySize,
		IN CONST UINT8 *	Iv,
		IN UINTN	IvSize,
		IN CONST UINT8 *	AData,
		IN UINTN	ADataSize,
		IN CONST UINT8 *	DataIn,
		IN UINTN	DataInSize,
		IN CONST UINT8 *	Tag,
		IN UINTN	TagSize,
		OUT UINT8 *	DataOut,
		OUT UINTN *	DataOutSize
	)

Performs AEAD AES-GCM authenticated decryption on a data buffer and additional authenticated data (AAD).

IvSize must be 12, otherwise FALSE is returned. KeySize must be 16, 24 or 32, otherwise FALSE is returned. TagSize must be 12, 13, 14, 15, 16, otherwise FALSE is returned. If additional authenticated data verification fails, FALSE is returned.

Parameters

[in]	Key	Pointer to the encryption key.
[in]	KeySize	Size of the encryption key in bytes.
[in]	Iv	Pointer to the IV value.
[in]	IvSize	Size of the IV value in bytes.
[in]	AData	Pointer to the additional authenticated data (AAD).
[in]	ADataSize	Size of the additional authenticated data (AAD) in bytes.
[in]	DataIn	Pointer to the input data buffer to be decrypted.
[in]	DataInSize	Size of the input data buffer in bytes.
[in]	Tag	Pointer to a buffer that contains the authentication tag.
[in]	TagSize	Size of the authentication tag in bytes.
[out]	DataOut	Pointer to a buffer that receives the decryption output.
[out]	DataOutSize	Size of the output data buffer in bytes.

Return values

TRUE	AEAD AES-GCM authenticated decryption succeeded.
FALSE	AEAD AES-GCM authenticated decryption failed.
