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))
}

@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!
