package md5

import "crypto/md5"

Package md5 implements the MD5 hash algorithm as defined in RFC 1321.

MD5 is cryptographically broken and should not be used for secure applications.

Examples

Constants 

const BlockSize = 64

The blocksize of MD5 in bytes. 

const Size = 16

The size of an MD5 checksum in bytes.

Functions

func New 

func New() hash.Hash

New returns a new hash.Hash computing the MD5 checksum. The Hash also implements encoding.BinaryMarshaler, encoding.BinaryAppender and encoding.BinaryUnmarshaler to marshal and unmarshal the internal state of the hash.

Example

Code:play  

package main

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

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

Output:

e2c569be17396eca2a2e3c11578123ed
Example (File)

Code:play  

package main

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

func main() {
	f, err := os.Open("file.txt")
	if err != nil {
		log.Fatal(err)
	}
	defer f.Close()

	h := md5.New()
	if _, err := io.Copy(h, f); err != nil {
		log.Fatal(err)
	}

	fmt.Printf("%x", h.Sum(nil))
}

func Sum 

func Sum(data []byte) [Size]byte

Sum returns the MD5 checksum of the data.

Example

Code:play  

package main

import (
	"crypto/md5"
	"fmt"
)

func main() {
	data := []byte("These pretzels are making me thirsty.")
	fmt.Printf("%x", md5.Sum(data))
}

Output:
