Function Documentation

SOPC_DJBHash()

uint64_t SOPC_DJBHash	(	const uint8_t *	data,
		size_t	len )

Hashes some data using DJB hash.

Parameters

data	The data to hash.
len	The length of the data, in bytes.

Returns

The resulting hash.

SOPC_DJBHash_Step()

uint64_t SOPC_DJBHash_Step	(	uint64_t	current,
		const uint8_t *	data,
		size_t	len )

Appends some data to a DJB hash.

Parameters

current	The current value of the hash.
data	The data to hash.
len	The length of the data, in bytes.

Returns

The resulting hash.

This interface allows computing a hash over various pieces of data in several calls.
