Description

The purpose of ParallelHash1 is to support the efficient hashing of very long strings, by taking advantage of the parallelism available in modern processors. ParallelHash supports the 128- and 256-bit security strengths

Function Documentation

parallelHashCompute()

error_t parallelHashCompute	(	uint_t	strength,
		size_t	blockSize,
		const void *	data,
		size_t	dataLen,
		const char_t *	custom,
		size_t	customLen,
		uint8_t *	digest,
		size_t	digestLen
	)

Digest a message using ParallelHash.

Parameters

[in]	strength	Number of bits of security (128 for ParallelHash128 and 256 for ParallelHash256)
[in]	blockSize	Block size in bytes for parallel hashing (B)
[in]	data	Pointer to the input string (X)
[in]	dataLen	Length of the input string
[in]	custom	Customization string (S)
[in]	customLen	Length of the customization string
[out]	digest	Calculated digest
[in]	digestLen	Expected length of the digest (L)

Returns

Error code

parallelHashFinal()

void parallelHashFinal	(	ParallelHashContext *	context,
		uint8_t *	digest,
		size_t	length
	)

Finish the ParallelHash message digest.

Parameters

[in]	context	Pointer to the ParallelHash context
[out]	digest	Calculated digest
[in]	length	Expected length of the digest (L)

Definition at line 225 of file parallel_hash.c.

parallelHashInit()

error_t parallelHashInit	(	ParallelHashContext *	context,
		uint_t	strength,
		size_t	blockSize,
		const char_t *	custom,
		size_t	customLen
	)

Initialize ParallelHash message digest context.

Parameters

[in]	context	Pointer to the ParallelHash context to initialize
[in]	strength	Number of bits of security (128 for ParallelHash128 and 256 for ParallelHash256)
[in]	blockSize	Block size in bytes for parallel hashing (B)
[in]	custom	Customization string (S)
[in]	customLen	Length of the customization string

Returns

parallelHashUpdate()

void parallelHashUpdate	(	ParallelHashContext *	context,
		const void *	data,
		size_t	length
	)

Update the ParallelHash context with a portion of the message being hashed.

Parameters

[in]	context	Pointer to the ParallelHash context
[in]	data	Pointer to the input string
[in]	length	Length of the string
