登录-用一个哈希值检查密码 [英] login - check password with hashed one

问题描述

这是我要哈希的代码

This is my code to hash

class hashing {
  private static $algo=''$2a'';
  private static $cost=''$10'';

  public static function unique_salt() {
	return substr(sha1(mt_rand()),0,22);
  }

 function hash($password) {			
	return crypt($password,self::$algo.self::$cost.''$''.self::unique_salt());
 }

 public static function check_password($hash,$password) {
	$full_salt=substr($hash,0,29);
	$new_hash=crypt($password,$full_salt);
	return ($hash==$new_hash);
 }  
}

这是我的登录页面

This is my login page

require("hashing.php");
$password=hashing::hash($_POST['txtPassword']);
$checkPassword=mysql_query("SELECT * from $tbl_name WHERE Password='".$password."'");
$resultPassword=mysql_fetch_row($checkPassword);

if(hashing::check_password($resultPassword['Password'],$_POST['txtPassword'])) {
  echo "login success!";
}
else {
 echo "login failed!";
}

用户输入正确的密码后，登录失败.我在哪里错了?

When the user inputs correct password, it is failing to login. Where am I wrong?

推荐答案

algo =''

2a''; 私人静态

2a''; private static

cost =''
