phpass0.1版本对应的javascript版本重写
司徒隐水
最近涉及到一个数据库移植时用户的密码是使用phpass0.1版本的php语言进行加密的，该加密算法是不可逆的，同样的字符串在不同的时候加密得到的加密字符串是不一样的，而且不可逆。所以必须要使用该类库所提供的解密接口来进行解密。
首先附上php版本的算法：PasswordHash.php
<?php
#
# Portable PHP password hashing framework.
#
# Version 0.1 / genuine.
#
# Written by Solar Designer <solar at openwall.com> in 2004-2006 and placed in
# the public domain.
#
# There's absolutely no warranty.
#
# The homepage URL for this framework is:
#
# http://www.openwall.com/phpass/
#
# Please be sure to update the Version line if you edit this file in any way.
# It is suggested that you leave the main version number intact, but indicate
# your project name (after the slash) and add your own revision information.
#
# Please do not change the "private" password hashing method implemented in
# here, thereby making your hashes incompatible. However, if you must, please
# change the hash type identifier (the "$P$") to something different.
#
# Obviously, since this code is in the public domain, the above are not
# requirements (there can be none), but merely suggestions.

大致说一下接口:
// Include phpass 库
require_once('phpass-03/PasswordHash.php')
// 初始化散列器为不可移植(这样更安全)
$hasher = new PasswordHash(8, false);
// 计算密码的哈希值。$hashedPassword 是一个长度为 60 个字符的字符串.
$hashedPassword = $hasher->HashPassword('123456'); //进行加密
// 你现在可以安全地将 $hashedPassword 保存到数据库中!// 通过比较用户输入内容（产生的哈希值）和我们之前计算出的哈希值，来判断用户是否输入了正确的密码
$hasher->CheckPassword('the wrong password', $hashedPassword); // false //进行解密
下面是使用js重写的该加密算法，使用js的版本接口能够解密php中的加密语言（毕竟只是语言不同，原理是一样的）PasswordHash.js
