How to get a MD5 hash from a string in Golang?

This is how I started to get a md5 hash from a string:

import "crypto/md5"

var original = "my string comes here"
var hash = md5.New(original)

But obvious开发者_高级运维ly this is not how it works. Can someone provide me a working sample for this?

---

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

func GetMD5Hash(text string) string {
   hash := md5.Sum([]byte(text))
   return hex.EncodeToString(hash[:])
}

Reference Sum，For me，following work well：

package main

import (
    "crypto/md5"
    "fmt"
)

func main() {
    data := []byte("hello")
    fmt.Printf("%x", md5.Sum(data))
}

I found this solution to work well

package main

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

func main() {
    var str string = "hello world"

    hasher := md5.New()
    hasher.Write([]byte(str))
    fmt.Println(str)
    fmt.Println(hex.EncodeToString(hasher.Sum(nil)))
}

From crypto/md5 doc:

package main

import (
    "crypto/md5"
    "fmt"
    "io"
)

func main() {
    h := md5.New()
    io.WriteString(h, "The fog is getting thicker!")
    fmt.Printf("%x", h.Sum(nil))
}

---

I use this to MD5 hash my strings:

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

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

Here is a function you could use to generate an MD5 hash:

// MD5 hashes using md5 algorithm
func MD5(text string) string {
    algorithm := md5.New()
    algorithm.Write([]byte(text))
    return hex.EncodeToString(algorithm.Sum(nil))
}

I put together a group of those utility hash functions here: https://github.com/shomali11/util

You will find FNV32, FNV32a, FNV64, FNV65a, MD5, SHA1, SHA256 and SHA512

just another answer

// MD5 hashes using md5 algorithm
func MD5(text string) string {
    data := []byte(text)
    return fmt.Sprintf("%x", md5.Sum(data))
}
