Codeigniter AES decode showing strange chars

i tryed:

$data = array('ip'=>'120.0.3.4','user'=>'robert');

 $this->load->library('encrypt');
    $this->encrypt->set_cipher(MCRYPT_RIJNDAEL_256);
    $this->encrypt->set_mode(MCRYPT_MODE_ECB);
    $key = random_string();
    $o=$this->encrypt->encode($data,$key);
var_dump($o);
$this->encrypt->set_cipher(MCRYPT_RIJNDAEL_256);
    $this->encrypt->set_mode(MCRYPT_MODE_ECB);
    $o = $this->encrypt->decode($o,$key);
    var_dump($o);

it retunrs strange chars in decoding:

string(44) "CVwMzZGkzagW4wHbUZfNpVWACQp2Fx4TeAO2KLqZs3I=" string(32) "��pz��xJx�jʊ8�Kw��mS�Y �1�_�"

any suggestion?

is this caused from the array encryption? i need to encrypt value by value instead of encrypt all the array to use the array of encrypted data?? thx

You are passing an array into $this->encrypt->encode(). The encode() method takes a string. See Encryption Class.

If you had PHP errors enabled you would also see:

A PHP Error was encountered
Severity: Warning
Message: mcrypt_encrypt() expects parameter 3 to be string, array given
Filename: libraries/Encrypt.php

Turn PHP errors on on your development machine to catch these.
