Variables

var Randomness = rand.New(RandomnessSource{})

Randomness contains an Rand instance of the previously defined RandomnessSource.

Types

type RandomnessSource

type RandomnessSource struct{}

RandomnessSource implements a cryptographically secure randomness source.

func (RandomnessSource) Int63

func (s RandomnessSource) Int63() int64

Int63 returns a non-negative random 63-bit integer as an int64.

func (RandomnessSource) Seed

func (s RandomnessSource) Seed(int64)

Seed is usually used to initialize the generator to a deterministic state but we want real randomness.

func (RandomnessSource) Uint64

func (s RandomnessSource) Uint64() (v uint64)

Uint64 returns a random 64-bit value as a uint64.
