Reader is a global, shared instance of a cryptographically strong pseudo-random generator. On Unix-like systems, Reader reads from /dev/urandom. On Windows systems, Reader uses the CryptGenRandom API.
var Reader io.Reader
func Int
func Int(rand io.Reader, max *big.Int) (n *big.Int, err os.Error)
Int returns a uniform random value in [0, max).
func Prime
func Prime(rand io.Reader, bits int) (p *big.Int, err os.Error)
Prime returns a number, p, of the given size, such that p is prime with high probability.
func Read
func Read(b []byte) (n int, err os.Error)
Read is a helper function that calls Reader.Read.
