Data Fields
unsigned int	strength
	The required strength of the bits generated.
int	prediction_resistance
	A flag to indicate that prediction resistance code is required.
ITEM	string
	A Byte array that adds additional seeding to provide uniqueness at instantiation or additional input at reseeding and generating time. More...
unsigned int	curve_type
	The type of elliptic curve to use when generating bits.
int( *	hashAlgorithm )(POINTER *)
	The hash algorithm to use during the generation of random data. More...
POINTER	hashAlgParams
	The parameters of the hash algorithm to use during the generation of random data (currently unused).
int	mode
	Operating mode: test/normal see ???

Field Documentation

int( * hashAlgorithm)(POINTER *)

The hash algorithm to use during the generation of random data. Set an AI against this field.

ITEM string

A Byte array that adds additional seeding to provide uniqueness at instantiation or additional input at reseeding and generating time. The array must be less than 1024 Bytes long.
