Exported Values

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(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(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.
var Reader io.Reader Reader is a global, shared instance of a cryptographically secure random number generator. On Linux and FreeBSD, Reader uses getrandom(2) if available, /dev/urandom otherwise. On OpenBSD, Reader uses getentropy(2). On other Unix-like systems, Reader reads from /dev/urandom. On Windows systems, Reader uses the CryptGenRandom API. On Wasm, Reader uses the Web Crypto API.
