go標準庫的學習-crypto/sha1

參考:https://studygolang.com/pkgdochtml

導入方式:golang

import "crypto/sha1"

sha1包實現了SHA1哈希算法,參見RFC 3174算法

 

Constants 

const BlockSize = 64

SHA1的塊大小。post

const Size = 20

SHA1校驗和的字節數。學習

func Sum

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

返回數據data的SHA1校驗和。ui

舉例:spa

package main

import (
    "fmt"
    "crypto/sha1"
)

func main() {
    data := []byte("His money is twice tainted: 'taint yours and 'taint mine.")
    fmt.Printf("%x\n", sha1.Sum(data)) //597f6a540010f94c15d71806a99a2c8710e747bd
}

 

func New

func New() hash.Hash

返回一個新的使用SHA1校驗的hash.Hash接口。code

可見go標準庫的學習-hashhtm

舉例:blog

package main

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

func main() {
    h := sha1.New()
    io.WriteString(h, "His money is twice tainted:")
    io.WriteString(h, " 'taint yours and 'taint mine.")
    fmt.Printf("%x\n", h.Sum(nil)) //597f6a540010f94c15d71806a99a2c8710e747bd
}
