Best way to convert an MD5 to decimal in Golang?

Question

In Python I can do

int(hashlib.md5('hello world').hexdigest(), 16)

which results in

125893641179230474042701625388361764291L

What's the equivalent in Golang to take an MD5 string and get the decimal representation?

Answer 1

You can do this with math/big .

package main

import (
    "crypto/md5"
    "encoding/hex"
    "fmt"
    "math/big"
)

func main() {
    bi := big.NewInt(0)
    h := md5.New()
    h.Write([]byte("hello world"))
    hexstr := hex.EncodeToString(h.Sum(nil))
    bi.SetString(hexstr, 16)
    fmt.Println(bi.String())
}
