Package md5

import "crypto/md5"
Overview

Overview

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

New

New (File)

Sum

Package files

md5.go md5block.go md5block_decl.go

Constants

The blocksize of MD5 in bytes.

const BlockSize = 64

The size of an MD5 checksum in bytes.

const Size = 16

func New

func New() hash.Hash

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

Example +

Code:

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:

+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 1.2

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

Sum returns the MD5 checksum of the data.

Example +

Code:

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

Output:

b0804ec967f48520697662a204f5fe72
