Functions

func GenSeed 

func GenSeed() (int64, error)

GenSeed generates a seed value using a cryptographically secure random number generator (CSRNG). Generated seed values should only be used to generate a truly random seed for a pseudo random number generator (PRNG), instead of using the program's initialization time. e.g. generated seed values do not make an arbitrary PRNG cryptographically secure.

Types

type LockedSource 

type LockedSource struct {
	sync.Mutex
	// contains filtered or unexported fields
}

LockedSource implements the rand.Source interface but is safe for usage with goroutines. Inspired by: golang.org/x/exp/rand

func NewLockedSource 

func NewLockedSource(seed int64) *LockedSource

NewLockedSource creates a new LockedSource

func (*LockedSource) Int63 

func (ls *LockedSource) Int63() int64

Int63 wraps the original source Int63 call in a mutex

func (*LockedSource) Seed 

func (ls *LockedSource) Seed(seed int64)

Seed wraps the original source Seed call in a mutex
