Function Documentation

◆ SDL_ROM_Checksum_init()

void SDL_ROM_Checksum_init ( SDL_ROM_Checksum_obj *const md )

This API will Initialize the buffer where hash value to be stored.

◆ SDL_ROM_Checksum_process()

int32_t SDL_ROM_Checksum_process	(	SDL_ROM_Checksum_obj *	md,
		uint8_t *	in,
		uint32_t	inlen
	)

This API is used to process the ROM region data.

Returns: status Success of the ROM Checksum. Success: SDL_PASS. Fail : SDL_EFAIL.

◆ SDL_ROM_Checksum_compress()

void SDL_ROM_Checksum_compress	(	SDL_ROM_Checksum_obj *	md,
		uint8_t *	buf
	)

This API is used to compress the data of ROM region and store the result in md->state.

◆ SDL_ROM_Checksum_done()

int32_t SDL_ROM_Checksum_done ( SDL_ROM_Checksum_obj * md )

This API will increase our data length with the help of padding ( because our algorithm can compress only 1024-bit length of data at a time) and will compress then will store final has value in md->state.

Returns: status Success of the ROM Checksum. Success: SDL_PASS. Fail : SDL_EFAIL.

◆ SDL_ROM_Checksum_compareResult()

int32_t SDL_ROM_Checksum_compareResult	(	uint64_t	buflen,
		SDL_ROM_Checksum_obj *	md,
		uint64_t *	golden_value
	)

This API will compare the resultant hash value of golden value.

Returns: status Success of the ROM Checksum. Success: SDL_PASS. Fail : SDL_EFAIL.

◆ SDL_memcpy()

void SDL_memcpy	(	void *	dest,
		void *	src,
		uint32_t	n
	)

This API will copy source pointer data to destination pointer.
