Functions
void	get_rand_128 (rng_128_t *rand128)
	Get 128-bit random numberThis method may be safely called from either core or from an IRQ, but be careful in the latter case as the call may block for a number of microseconds waiting on more entropy. More...
uint64_t	get_rand_64 (void)
	Get 64-bit random numberThis method may be safely called from either core or from an IRQ, but be careful in the latter case as the call may block for a number of microseconds waiting on more entropy. More...
uint32_t	get_rand_32 (void)
	Get 32-bit random numberThis method may be safely called from either core or from an IRQ, but be careful in the latter case as the call may block for a number of microseconds waiting on more entropy. More...
