Constants

const BlockSize = 64

The blocksize of SHA1 in bytes.

const Size = 20

The size of a SHA1 checksum in bytes.

Functions

func New

func New() hash.Hash

New returns a new hash.Hash computing the SHA1 checksum.

Example

package main

import (
	"crypto/sha1"
	"fmt"
	"io"
)

func main() {
	h := sha1.New()
	io.WriteString(h, "His money is twice tainted: 'taint yours and 'taint mine.")
	fmt.Printf("% x", h.Sum(nil))
}

Output:

59 7f 6a 54 00 10 f9 4c 15 d7 18 06 a9 9a 2c 87 10 e7 47 bd

func Sum

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

Sum returns the SHA1 checksum of the data.
