Question

我的配置是（来自phpinfo（））：

PHP Version 5.3.10
Registered Stream Filters: convert.iconv.*, mcrypt.*, mdecrypt.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, zlib.*, bzip2.* 

mcrypt support: enable
mcrypt_filter support: enable
Version: 2.5.8
Supported ciphers: cast-128 gost rijndael-128 twofish cast-256 loki97 rijndael-192 saferplus wake blowfish-compat des rijndael-256 serpent xtea blowfish enigma rc2 tripledes arcfour
Supported modes: cbc cfb ctr ecb ncfb nofb ofb stream

所以你看我启用了mcrypt。

我试试

mcrypt_module_open('rijndael-256', '', 'ofb', '');

没关系。

但是当我尝试像

这样的东西时

stream_filter_append($fp, 'mcrypt.rijndael-256', STREAM_FILTER_WRITE, $opts);

我有两个警告

stream_filter_append(): Could not open encryption module in ...
stream_filter_append(): unable to create or locate filter &quot;mcrypt.rijndael-256&quot; in ...

我认为编写

是错误的

stream_filter_append($fp, 'rijndael-256', STREAM_FILTER_WRITE, $opts); // without 'mcrypt.*'

但在这种情况下我只有一个警告

stream_filter_append(): unable to create or locate filter &quot;rijndael-256&quot; in ...

最后一件事。使用＆＃34; rot13＆＃34;进行加密/描述运作良好

stream_filter_append($fp, "string.rot13", STREAM_FILTER_WRITE);

所以问题是如何使用某些mcrypt方法加密/解密？

Answer 1

对不起，我忽略了一些重要的细节。还有一个字符串：

$opts = array('iv' => $iv, 'key' => $key, 'mode' => 'stream');
stream_filter_append($fp, 'mcrypt.rijndael-256', STREAM_FILTER_WRITE, $opts);

当然它失败了，因为在STREAM模式下不支持Rijndael-256。非常感谢您的评论，很抱歉给您带来麻烦。

PHP - stream_filter_append，无法定位过滤器（mcrypt）
