Go语言Web: 密码散列

使用bcrypt加密你的密码，需要使用go get安装一个go语言bcrypt库，代码：

$ go get golang.org/x/crypto/bcrypt

使用下面的代码使用bcrypt库，代码：

// passwords.go
package main

import (
    "fmt"

    "golang.org/x/crypto/bcrypt"
)

func HashPassword(password string) (string, error) {
    bytes, err := bcrypt.GenerateFromPassword([]byte(password), 14)
    return string(bytes), err
}

func CheckPasswordHash(password, hash string) bool {
    err := bcrypt.CompareHashAndPassword([]byte(hash), []byte(password))
    return err == nil
}

func main() {
    password := "secret"
    hash, _ := HashPassword(password) // 无视错误

    fmt.Println("Password:", password)
    fmt.Println("Hash:    ", hash)

    match := CheckPasswordHash(password, hash)
    fmt.Println("Match:   ", match)
}

$ go run passwords.go
Password: secret
Hash:     $2a$14$ajq8Q7fbtFRQvXpdCq7Jcuy.Rx1h/L4J60Otx.gyNLbAYctGMJ9tK
Match:    true
