I'm having a problem with reading the encrpyted cookie. Debugging revealed that Security::cipher() on server is somehow broken. Is there anyway I could solve it?

下面是细分.

$key = Configure::read('Security.salt');

$val = Security::cipher($value, $key);
debug($val);
$ret = Security::cipher($val, $key);
debug($ret);

本地

appviewspageshome.ctp (line 17)
�J��WtJ0�

appviewspageshome.ctp (line 19)
Hello World

服务器

app/views/pages/home.ctp (line 17)

推荐答案

Security::cipher() 正在使用 srand() 函数，该函数被 suhosin 模块禁用，该模块默认用于许多 Apache、PHP 服务器.

Security::cipher() is using srand() function which is disabled by suhosin module which comes as default for many Apache, PHP servers.

禁用 suhosin 和 Security::cipher() 将正常工作.

Disable suhosin and Security::cipher() will work fine.
