这种格式的MD5是不是和DZ的MD5不一样的?

我用的是一个ASP以前叫"迷你城市"的社区, 现在想转换到DZ ,我用Navicat for MySQL把用户数据导入到MYSQL里了, 发现这个MD5加密问题, 原社区用的MD5原来的密码是16位的,  看这段代码MD5=LCase(WordToHex(b) & WordToHex(c))应该是取了中间的那段吧, 但是和UC数据库里的对比,却发现完全不一样,  请教下各位老大, 这个到底是怎么回事....

原社区用的MD5文件"md5_inc.asp" 代码如下:

你不是要告诉我准备反编译MD5吧？

貌似DZ7.0的数据是32位MD5加密

5555...不是啊,我原来的数据是用这个MD5加密的,16位的, 我用DV8转换后那个补丁还是无法登陆.

我打开数据库看了密码的字段, 发现完全不一样的,  没有任何相邻4个字母是一样的, 所以绝对不是取中间或者

取两边, 那是不是算法不一样?  我原来论坛的MD5密码在 www.cmd5.com上能够破解得到,

又证明是这个正常的MD5加密了..

((em:01))刚才试了一下...DZ的MD5密码在www.cmd5.com上破解不了....

我靠啊,终于搞定了,
把
md5(substr(md5($password),8,16).$user['salt'])
换成
substr(md5($password),8,16)
后就行了, 可怜我一点都不懂php, 猜了好久才猜到..

还有个问题, 我的数据库会员表里有部分会员的密码是没有用MD5加密的,
我想让他登陆后自动改成DZ的加密方式,我改成下面这个样子, 能够登陆了, 但是却不会把未MD5的密码加密...
错在哪里呢?

$user['salt'])
这是个随即变量
