php 5.4的password_hash等价物?

2022-01-22 00:00:00 hash passwords salt php

我使用安装了 php 5.5 的 XAMPP 开发了我的网站.我只是意识到我的主机只有 php 5.4(还不能更新到 5.5).我的问题是我不能使用新的 php 5.5 password_hash() 功能.php 5.4 是否有等效的盐散列方法?

I developed my site using XAMPP with php 5.5 installed. I just realize that my host only has php 5.4 (cannot update to 5.5 yet). My problem is that I cannot use the new php 5.5 password_hash() feature. Is there an equivalent method for hashing with salt for php 5.4?

有没有办法让这个等效代码(如下)在 php 5.4 中工作?

Is there a way to get this equivalent code (below) to work in php 5.4?

$options = [
  'salt' => uniqid(mt_rand(), true),
  'cost' => 12 
];
$hash = password_hash($mypassword, PASSWORD_DEFAULT, $options);

推荐答案

使用password_compat.这是一个向后兼容的库，用于模拟 password_hash() 在旧版本的 PHP (5.3.7+) 中.

Use password_compat. It's a backward compatible library to emulate password_hash() in older versions of PHP (5.3.7+).
