Instance Property


The seed data that determines the random source’s behavior.


@property(nonatomic, copy) NSData *seed;


Any two random sources initialized with the same seed data will generate the same sequence of random numbers. To replicate the behavior of an existing GKARC4RandomSource instance, read this property and then create a new instance by passing the resulting data to the initWithSeed: initializer.

For a source of high-entropy seed data, see the SecRandomCopyBytes function.
