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.

Example

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:

func Sum

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

Sum returns the MD5 checksum of the data.

Example

package main

import (
	"crypto/md5"
	"fmt"
)

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