base64 encoding _ golang

This syntax imports the encoding/base64 package with the b64 name instead of the default 64. It'll save us some space below

package main

import (
    b64 "encoding/base64"
    "fmt"
)

func main() {

    data := "abc123!?$*&()'-=@~"

    sEnc := b64.StdEncoding.EncodeToString([]byte(data))
    fmt.Println(sEnc)

    sDec, _ := b64.StdEncoding.DecodeString(sEnc)
    fmt.Println(string(sDec))

    uEnc := b64.URLEncoding.EncodeToString([]byte(data))
    fmt.Println(uEnc)

    uDec, _ := b64.URLEncoding.DecodeString(uEnc)
    fmt.Println(string(uDec))

}
