package main

import (
    "encoding/base64"
    "fmt"
)

func main() {

    str := base64.StdEncoding.EncodeToString([]byte("nilpointer.net"))
    fmt.Println("Encode:", str)

    data, err := base64.StdEncoding.DecodeString(str)
    if err != nil {
        fmt.Println("Error:", err)
    }

    fmt.Println("Decode:", string(data))

}    

Output

Encode: bmlscG9pbnRlci5uZXQ=
Decode: nilpointer.net
