先 go get 安装 golang.org/x/crypto/bcrypt 包来实现。
对用户的密码进行hash处理，可以用下面两个函数实现。
package main
import (
"fmt"
"golang.org/x/crypto/bcrypt"
)
func PasswordHash(password string) (string, error) {
bytes, err := bcrypt.GenerateFromPassword([]byte(password), bcrypt.DefaultCost)
return string(bytes), err
}
func PasswordVerify(password, hash string) bool {
err := bcrypt.CompareHashAndPassword([]byte(hash), []byte(password))
return err == nil
}
func main() {
password := "feishuai.vip"
hash, _ := PasswordHash(password)
fmt.Println("密码:", password)
fmt.Println("hash:", hash)
match := PasswordVerify(password, hash)
fmt.Println("验证:", match)
}
