func New

func New() hash.Hash

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

Example

func Sum

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

Sum returns the SHA1 checksum of the data.

Example

package main

import (
	"crypto/sha1"
	"fmt"
)

func main() {
	data := []byte("This page intentionally left blank.")
