Go hex.EncodeToString: Encode Byte Slice to Hex String

The 'hex.EncodeToString' function in Go is used to encode a byte slice into its hexadecimal representation as a string. The function takes a byte slice as an argument and returns a string.

Here is an example of how to use 'hex.EncodeToString':

package main

import (
    "encoding/hex"
    "fmt"
)

func main() {
    data := []byte('hello world')
    encoded := hex.EncodeToString(data)
    fmt.Println(encoded)
}

The output of this program will be:

68656c6c6f20776f726c64

This is the hexadecimal representation of the string 'hello world'.
