Constructor & Destructor Documentation

◆ jrand() [1/2]

ProtocolPP::jrand::jrand ( )

Standard constructor for the jrand class. Seeded with 0x5489UL, RandomPool seeded from hardware global use_crypto is set to false (use_crypto can be set on a function by function basis)

◆ jrand() [2/2]

ProtocolPP::jrand::jrand	(	uint64_t	myseed,
		bool	use_crypto = `false`
	)

explicit

Constructor for jrand that accepts an uint64_t for the seed

Parameters

myseed	- seed to initialize psuedo-random number generator
use_crypto	- Use cryptographic quality random numbers Sets use in the randomizer globally, overrides use_crytpo in individual functions if set to true
