Golang utils for copypasta.

util.go

package main

import (
	"crypto/md5"
	"crypto/rand"
	"encoding/hex"
	"encoding/json"
	"io"
	"net/http"
)

func RandomString() string {
	id := make([]byte, 32)
	_, err := io.ReadFull(rand.Reader, id)
	if err != nil {
		panic(err) // This shouldn't happen
	}
	return hex.EncodeToString(id)
}

func MD5(s string) string {
        h := md5.Sum([]byte(s))
	return string(hex.EncodeToString(h[:]))
}

h := md5.Sum([]byte(s))
return string(hex.EncodeToString(h[:]))

Could be replaced with

return string(hex.EncodeToString(md5.Sum([]byte(s)) [:]))

Well, it doesn't seem to work: http://play.golang.org/p/HyTY4aY87k
