Dencryption of md5 string in Go

So I came across the following code in Go trying to explain how md5 hashing works.

package main

import (
    "crypto/md5"
    "fmt"
)

func HashFunc(word string) {

    hash := md5.New()
    bytes := []byte(word)

    hash.Write(bytes)
    hashValue := hash.Sum(nil)
    hashSize := hash.Size()

    for n := 0; n < hashSize; n += 4 {
        var val = uint32(hashValue[n])<<24 +
            uint32(hashValue[n+1])<<16 +
            uint32(hashValue[n+2])<<8 +
            uint32(hashValue[n+3])
        fmt.Printf("%x ", val)
    }
    fmt.Println()
}

I would simply like to know how to dencrypt any data that is encrypted by the above function.

>Solution :

You don’t

MD5 is a hash function, not an encryption function. The point of a hash function is that it is impossible to covert the output back into the input
