Random number generation with crypto/rand in Go
Random number is useful in many applications. From salting password to enabling secure transactions.
In this tutorial, we will learn how to generate random number in Go with crypto/rand library.
File : crypto-rand.go
package main
import "encoding/binary"
import "crypto/rand"
func main() {
var n int32
binary.Read(rand.Reader, binary.LittleEndian, &n)
println(n)
