Function Documentation

void randpool_add	(	EntropyPool *	pool,
		void *	data,
		size_t	entropy
	)

Add.

Parameters:

	entropy	bits from
	data	buffer to the entropy
	pool

Definition at line 121 of file randpool.c.

void randpool_get	(	EntropyPool *	pool,
		void *	_data,
		size_t	n_byte
	)

Get.

Parameters:

	n_byte	from entropy pool. If n_byte is larger than number byte of entropy in entropy pool, randpool_get continue to generate pseudocasual value from previous state of pool.
	n_byte	number fo bytes to read.
	pool	is the pool entropy context.
	_data	is the pointer to write the random data to.

Definition at line 206 of file randpool.c.

void randpool_init	(	EntropyPool *	pool,
		void *	_data,
		size_t	len
	)

Randpool function initialization.

The entropy pool can be initialize also with a previous entropy pool.
