GoLang replacement for PHP's base64_decode [Golang Play | edit | history]
// Go provides built-in support for [base64
// encoding/decoding](http://en.wikipedia.org/wiki/Base64).

package main

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

func main() {

    // Here's the `string` we'll encode/decode.
    data := "abc123!?$*&()'[email protected]~"

    // Go supports both standard and URL-compatible
    // base64. Here's how to encode using the standard
    // encoder. The encoder requires a `[]byte` so we
    // cast our `string` to that type.
    sEnc := b64.StdEncoding.EncodeToString([]byte(data))
    fmt.Println(sEnc)

    // Decoding may return an error, which you can check
    // if you don't already know the input to be
    // well-formed.
    sDec, _ := b64.StdEncoding.DecodeString(sEnc)
    fmt.Println(string(sDec))
    fmt.Println()

    // This encodes/decodes using a URL-compatible base64
    // format.
    uEnc := b64.URLEncoding.EncodeToString([]byte(data))
    fmt.Println(uEnc)
    uDec, _ := b64.URLEncoding.DecodeString(uEnc)
    fmt.Println(string(uDec))
}
