AesCbcDecrypt()

BOOLEAN EFIAPI AesCbcDecrypt	(	IN VOID *	AesContext,
		IN CONST UINT8 *	Input,
		IN UINTN	InputSize,
		IN CONST UINT8 *	Ivec,
		OUT UINT8 *	Output
	)

Performs AES decryption on a data buffer of the specified size in CBC mode.

Return FALSE to indicate this interface is not supported.

Parameters

[in]	AesContext	Pointer to the AES context.
[in]	Input	Pointer to the buffer containing the data to be encrypted.
[in]	InputSize	Size of the Input buffer in bytes.
[in]	Ivec	Pointer to initialization vector.
[out]	Output	Pointer to a buffer that receives the AES encryption output.

Return values

FALSE

This interface is not supported.

AesGetContextSize()

UINTN EFIAPI AesGetContextSize

(

VOID

)

Retrieves the size, in bytes, of the context buffer required for AES operations.

Return zero to indicate this interface is not supported.

Return values

0	This interface is not supported.

AesInit()

BOOLEAN EFIAPI AesInit	(	OUT VOID *	AesContext,
		IN CONST UINT8 *	Key,
		IN UINTN	KeyLength
	)

Initializes user-supplied memory as AES context for subsequent use.

Return FALSE to indicate this interface is not supported.

Parameters

[out]	AesContext	Pointer to AES context being initialized.
[in]	Key	Pointer to the user-supplied AES key.
[in]	KeyLength	Length of AES key in bits.

Return values

FALSE

This interface is not supported.
