如何在Golang中实现用户密码加密_Golang 用户密码加密实践

package main

import (
    "fmt"
    "golang.org/x/crypto/bcrypt"
)

func hashPassword(password string) (string, error) {
    // 使用默认成本（DefaultCost）生成哈希，通常为10
    hashedBytes, err := bcrypt.GenerateFromPassword([]byte(password), bcrypt.DefaultCost)
    if err != nil {
        return "", err
    }
    return string(hashedBytes), nil
}

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

func main() {
    password := "mysecretpassword"

    // 加密密码
    hashed, err := hashPassword(password)
    if err != nil {
        panic(err)
    }
    fmt.Println("Hashed:", hashed)

    // 验证密码
    matched := checkPassword(hashed, "mysecretpassword")
    fmt.Println("Matched:", matched) // true

    matched = checkPassword(hashed, "wrongpassword")
    fmt.Println("Matched:", matched) // false
}

hashed, err := bcrypt.GenerateFromPassword([]byte(password), 12)
