Problem with mbstring.internal_encoding, mcrypt and php-fpm

[Condor]

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

Hristo,

Try changing the php.ini config:

mbstring.func_overload 0

See if that helps your issue, more on what it does:
