Hristo, Try changing the php.ini config: mbstring.func_overload 0 See if that helps your issue, more on what it does: http://php.net/manual/en/mbstring.overload.php [3] Aziz On Mon, Sep 23, 2013 at 8:23 AM, Condor <condor@stz-bg.com> wrote:

Hello, from two days I have strange problem with this param mbstring.internal_encoding on nginx and php-fpm. I use php version 5.4.20 and when I setting mbstring.internal_encoding I have a problem with mcrypt. NOTICE: PHP message: PHP Warning:  mcrypt_generic_init(): Iv size incorrect; supplied length: 12, needed: 8 in file.php I setup php.ini file: zend.multibyte = On default_mimetype = "text/html" default_charset = "UTF-8" mbstring.internal_encoding = UTF-8 and here is function:

 85         private function decrypt($blob)
 86         {
 87                 $deckey = $_SESSION['key'];
 88                 $realkey = sha1($deckey, true);
 89                 $rawblob = hex2bin($blob); /* binary

blob */

 90                 $td =

mcrypt_module_open($this->CIPHER, "", MCRYPT_MODE_CFB, "");

 91                 $iv = mb_substr($rawblob, 0,

mcrypt_enc_get_iv_size($td)); /* IV */

 92                 if (mb_strlen($iv) <

mcrypt_enc_get_iv_size($td)) return FALSE;

 93                 $ct = mb_substr($rawblob,

mcrypt_enc_get_iv_size($td)); /* CipherText */

 94    --->         mcrypt_generic_init($td, $realkey, $iv);
 95                 $unblob = mdecrypt_generic($td, $ct);
 96                 mcrypt_generic_deinit($td);
 97                 $pt = mb_substr($unblob, 20);
 98                 $check = mb_substr($unblob, 0, 20);
 99                 if ($check != sha1($pt, true))
100                 {
101                         return FALSE;
102                 } else {
103                         return $pt;
104                 }
105         }

The same code with the same config options is worked fine with apache httpd. Any one can give me a little help ? Thanks Regards, Hristo S.
