func main() {
    message := []byte("Hello, World!")
    encodedMessage := base64.StdEncoding.EncodeToString(message)
    fmt.Println(encodedMessage)
    // encodedMessage "SGVsbG8sIFdvcmxkIQ=="
    decodedMessage, err := base64.StdEncoding.DecodeString(encodedMessage)
    if err != nil {
        fmt.Println("Error decoding message:", err)
        return
    }
    fmt.Println(string(decodedMessage))
