How do I convert [Size]byte to string in Go?

Question

I have a sized byte array that I got after doing md5.Sum().

data := []byte(\"testing\")
var pass string 
var b [16]byte
b = md5.Sum(data)
pass =         


        

Answer 1

A little late but keep in mind that using string(b[:]) will print mostly invalid characters.

If you're trying to get a hex representation of it like php you can use something like:

data := []byte("testing")
b := md5.Sum(data)

//this is mostly invalid characters
fmt.Println(string(b[:]))

pass := hex.EncodeToString(b[:])
fmt.Println(pass)
// or
pass = fmt.Sprintf("%x", b)
fmt.Println(pass)

Answer 2

Make a slice of it:

pass = string(b[:])

Answer 3

it can be solved by this

pass = fmt.Sprintf("%x", b)

or

import "encoding/base64"
pass = base64.StdEncoding.EncodeToString(b[:])

this will encoding it to base64 string

Answer 4

You can refer to it as a slice:

pass = string(b[:])
