如何programmaticaly建立一个APR1-MD5使用PHP [英] How to programmaticaly build an APR1-MD5 using PHP

问题描述

就像我想生成一个PHP的htpasswd文件条目href=\"http://stackoverflow.com/questions/39916/programmaticly-building-htpasswd/\">这个问题。然而，它需要是APR1（Apache）的样式，如在原来的答案上述（答案没有显示如何实现APR1样式），以mod_dav_svn的工作

Much like this question I want to generate an htpasswd file entry from PHP. However it needs to be the APR1 (Apache) style, as mentioned in the original answer (The answer did not show how to implement the APR1 style), to work with mod_dav_svn.

我似乎无法找到工作的实施，将创建的密码。

I can't seem to find a working implementation that will create the password.

我发现这个（我忘了现在的地方）：

I found this (I forget where now):

function crypt_apr1_md5($plainpasswd) {
    $salt = substr(str_shuffle("abcdefghijklmnopqrstuvwxyz0123456789"), 0, 8);
    $len = strlen($plainpasswd);
    $text = $plainpasswd.'$apr1$'.$salt;
    $bin = pack("H32", md5($plainpasswd.$salt.$plainpasswd));
    for($i = $len; $i > 0; $i -= 16) { $text .= substr($bin, 0, min(16, $i)); }
    for($i = $len; $i > 0; $i >>= 1) { $text .= ($i & 1) ? chr(0) : $plainpasswd{0}; }
    $bin = pack("H32", md5($text));
    for($i = 0; $i < 1000; $i++) {
        $new = ($i & 1) ? $plainpasswd : $bin;
        if ($i % 3) $new .= $salt;
        if ($i % 7) $new .= $plainpasswd;
        $new .= ($i & 1) ? $bin : $plainpasswd;
        $bin = pack("H32", md5($new));
    }
    for ($i = 0; $i < 5; $i++) {
        $k = $i + 6;
        $j = $i + 12;
        if ($j == 16) $j = 5;
        $tmp = $bin[$i].$bin[$k].$bin[$j].$tmp;
    }
    $tmp = chr(0).chr(0).$bin[11].$tmp;
    $tmp = strtr(strrev(substr(base64_encode($tmp), 2)),
    "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/",
    "./0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz");
    return "$"."apr1"."$".$salt."$".$tmp;
}

不过，这并不产生一个工作密码。我认为这可能是是与Apache的版本，但我不知道。 （我在CentOS 5上运行）

But it doesn't generate a working password. I think this might be something to do with the version of apache but am not sure. (I am running on CENTOS 5)

推荐答案

原来我犯了一个错误，此功能对事实上创建工作APR1 HTPASSWD条目。他们这样做看起来不同的部分之外的Apache的创造，但他们做的工作。

It turns out I made a mistake and this function does in fact create working APR1 htpasswd entries. They do look different to the ones Apache creates but they do work.
