Constants

const BlockSize = 64

The blocksize of MD5 in bytes.

const Size = 16

The size of an MD5 checksum in bytes.

func New Uses

func New() hash.Hash

New returns a new hash.Hash computing the MD5 checksum.

Code:play 

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:

Code:play 

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 Uses

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

Sum returns the MD5 checksum of the data.

Code:play 

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

Output:
