Overview ¶

Package rand implements a cryptographically secure random number generator.

Variables

var Reader io.Reader

Reader is a global, shared instance of a cryptographically secure random number generator.

Functions ¶

func Int ¶

func Int(rand io.Reader, max *big.Int) (n *big.Int, err error)

Int returns a uniform random value in [0, max). It panics if max <= 0.

func Prime ¶

func Prime(rand io.Reader, bits int) (p *big.Int, err error)

Prime returns a number, p, of the given size, such that p is prime with high probability. Prime will return error for any error returned by rand.Read or if bits < 2.

func Read ¶

func Read(b []byte) (n int, err error)

Read is a helper function that calls Reader.Read using io.ReadFull. On return, n == len(b) if and only if err == nil.
