Overview

Package random provides facilities for generating random or pseudorandom cryptographic objects.

Functions

func Bits

func Bits(bitlen uint, exact bool, rand cipher.Stream) []byte

Bits chooses a uniform random BigInt with a given maximum BitLen. If 'exact' is true, choose a BigInt with _exactly_ that BitLen, not less

func Bytes

func Bytes(b []byte, rand cipher.Stream)

Bytes fills a slice with random bytes from rand.

func Int

func Int(mod *big.Int, rand cipher.Stream) *big.Int

Int chooses a uniform random big.Int less than a given modulus

func New

func New() cipher.Stream

New returns a new cipher.Stream that gets random data from Go's crypto/rand package. The resulting cipher.Stream can be used in multiple threads.
