Go言語でランダムな文字列を生成する

ランダムな64ビットのintを生成して、基数を36に変更することで、英数混合のランダムな文字列が生成できる。

main.go
package main

import (
    "encoding/binary"
    "crypto/rand"
    "strconv"
)

func main() {
    println(random())
    println(random())
    println(random())
}

func random() string {
    var n uint64
    binary.Read(rand.Reader, binary.LittleEndian, &n)
    return strconv.FormatUint(n, 36)
}
