Detailed Description

Encrypt and decrypt data with AES-256 in CTR mode using different implementations.

Function Documentation

EXPORT_DLL void salmon_expandKey	(	const unsigned char *	key,
		unsigned char *	expandedKey )

extern

Expand an AES-256 32-byte key to a 240-byte set of round keys.

Parameters

key	The AES-256 (32-byte) key to expand.
expandedKey	The expanded key (240-bytes).

EXPORT_DLL void salmon_init ( int aesImplType )

extern

Initialize the transformer.

Parameters

aesImplType The AES implementation: see: AES_IMPL_AES_INTR, AES_IMPL_TINY_AES, AES_IMPL_AES_GPU

EXPORT_DLL int salmon_transform	(	const unsigned char *	expandedKey,
		unsigned char *	counter,
		const unsigned char *	srcBuffer,
		int	srcOffset,
		unsigned char *	destBuffer,
		int	destOffset,
		int	count )

extern

Transform the data using AES-256 CTR mode.

Parameters

expandedKey	The expanded AES-256 key (240 bytes), see aes_key_expand
counter	The counter to use.
srcBuffer	The source byte array.
srcOffset	The source byte offset.
destBuffer	The destination byte array.
destOffset	The destination byte offset.
count	The number of bytes to transform.
