Simple playing with Nuhach's uuid.

nuhatch_uuid.go

package main

import (
	"encoding/base64"
	"fmt"

	uuid "github.com/nu7hatch/gouuid" // It seems that github.com/satori/go.uuid has more advanced functionality.
)

func main() {
	u, e := uuid.NewV4()

	if e != nil {
		panic("Couldn't generate a uuid v4.")
	}
	fmt.Println("uuid is [16]bytes:", u)
	fmt.Println("uuid.String(), which is 36 bytes:", u.String())

	s := base64.StdEncoding.EncodeToString([]byte(u.String()))
	fmt.Println("base64:", s)

	original, _ := base64.StdEncoding.DecodeString(s)
	fmt.Println("Original uuid as bytes:", original)
	fmt.Println("Original uuid:", string(original))
}
