密码安全最佳实践包括：使用 bcrypt 哈希密码、使用随机 salt、检查密码长度和复杂性、限制登录尝试次数、使用双因素认证、妥善存储哈希密码。实战案例中，注册流程包括验证密码强度、生成随机 salt、哈希密码并将其与 salt 一起存储在数据库中。登录流程涉及从数据库中检索哈希并将其与输入的密码进行比较，验证后实施会话管理。
在 Go 框架中处理密码时，遵循最佳安全实践至关重要。以下是确保密码安全性的关键步骤：
golang.org/x/crypto/bcrypt 包实现 bcrypt：package main
import (
"golang.org/x/crypto/bcrypt"
)
func hashPassword(password string) ([]byte, error) {
return bcrypt.GenerateFromPassword([]byte(password), bcrypt.DefaultCost)
}crypto/rand 包生成随机 salt：func generateSalt() ([]byte, error) {
return rand.Bytes(16)
}func validatePassword(password string) error {
if len(password) < 8 {
return errors.New("Password must be at least 8 characters long")
}
if !regexp.MustCompile(`(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9]).+$`).MatchString(password) {
return errors.New("Password must contain at least one lowercase letter, one uppercase letter, and one digit")
}
return nil
}net/http 包中的 RateLimit 函数或自定义中间件来限制登录请求：func loginHandler(w http.ResponseWriter, r *http.Request) {
if loginAttempts := r.Context().Value("loginAttempts"); loginAttempts > 10 {
http.Error(w, "Too many failed login attempts", http.StatusTooManyRequests)
return
}
}实战案例：
假设我们有一个简单的 Go 应用程序，允许用户注册和登录。以下是如何在应用程序中实施这些最佳实践：
