SWIFFT_Compact()

void LIBSWIFFT_API() SWIFFT_Compact	(	const BitSequence	output[SWIFFT_OUTPUT_BLOCK_SIZE],
		BitSequence	compact[SWIFFT_COMPACT_BLOCK_SIZE]
	)

Compacts a hash value of SWIFFT. The result is not composable with other compacted hash values.

Parameters

[in]	output	the hash value of SWIFFT, of size 128 bytes (1024 bit).
[out]	compact	the compacted hash value of SWIFFT, of size 64 bytes (512 bit).

SWIFFT_CompactMultiple()

void LIBSWIFFT_API() SWIFFT_CompactMultiple	(	int	nblocks,
		const BitSequence	output[SWIFFT_OUTPUT_BLOCK_SIZE],
		BitSequence	compact[SWIFFT_COMPACT_BLOCK_SIZE]
	)

Compacts a hash value of SWIFFT for multiple blocks. The result is not composable with other compacted hash values.

Parameters

[in]	nblocks	the number of blocks to operate on.
[in]	output	the hash value of SWIFFT, of size 128 bytes (1024 bit).
[out]	compact	the compacted hash value of SWIFFT, of size 64 bytes (512 bit).

SWIFFT_Compute()

void LIBSWIFFT_API() SWIFFT_Compute	(	const BitSequence	input[SWIFFT_INPUT_BLOCK_SIZE],
		BitSequence	output[SWIFFT_OUTPUT_BLOCK_SIZE]
	)

Computes the result of a SWIFFT operation. The result is composable with other hash values.

Parameters

[in]	input	the input of 256 bytes (2048 bit).
[out]	output	the resulting hash value of SWIFFT, of size 128 bytes (1024 bit).

SWIFFT_ComputeMultiple()

void LIBSWIFFT_API() SWIFFT_ComputeMultiple	(	int	nblocks,
		const BitSequence *	input,
		BitSequence *	output
	)

Computes the result of multiple SWIFFT operations. The result is composable with other hash values.

Parameters

[in]	nblocks	the number of blocks to operate on.
[in]	input	the blocks of input, each of 256 bytes (2048 bit).
[out]	output	the resulting blocks of hash values of SWIFFT, each of size 128 bytes (1024 bit).

SWIFFT_ComputeMultipleSigned()

void LIBSWIFFT_API() SWIFFT_ComputeMultipleSigned	(	int	nblocks,
		const BitSequence *	input,
		const BitSequence *	sign,
		BitSequence *	output
	)

Computes the result of multiple SWIFFT operations. The result is composable with other hash values.

Parameters
