Golang - How to hash a string using MD5.

md5-example.go

import (
    "crypto/md5"
    "encoding/hex"
)

func GetMD5Hash(text string) string {
    hasher := md5.New()
    hasher.Write([]byte(text))
    return hex.EncodeToString(hasher.Sum(nil))
}

cool! merci

Thanks!

Thanks !

for big string I use:

import (
    "crypto/md5"
    "fmt"
)

func DigestString(s *string) string {
    return fmt.Sprintf("%x", md5.Sum([]byte(*s)))
}

Thanks !

I want to convert string to MD5 with base64 encoded string.
As I get that in PHP as like below.
But I need it in Golang

<?php
$str = "hello";
$str2 = mb_convert_encoding($str, "utf-8");
echo base64_encode(md5($str2,true));

Test url for PHP code "http://sandbox.onlinephpfunctions.com/code/e21dd185093817217427b6cd4e58a223e6ca3b27"
I tried many examples in Golang but didn't get success.

Hey Sergio from 2014, you're not using Go anymore for years! You're now on Elixir for three years.

Sergio from 2029, are you an Elixir guru yet? Do you truly grok the Erlang's OTP and all the goodies it gives for free? Keep me posted!

👍 Bueno

@sergiotapia what is the importance of hex.EncodeToString?

@bipin-mi I have the same problem as you

@bipin-mi I have the same problem as you

I get solution with below code snippet

str := "hello"
hasher := md5.New()
hasher.Write([]byte(str))
encodedString := b64.StdEncoding.EncodeToString(hasher.Sum(nil))
fmt.Println(encodedString)

Please see the benchmark of different methods for generating MD5：https://play.golang.org/p/9bAidOZFgFt

func makeMD5(in string) string {
	binHash := md5.Sum([]byte(in))
	return hex.EncodeToString(binHash[:])
}

Really helpful, thanks!
