Password encrypt

[thestars]

I used the following function to encrypt password.

 

function encrypt($text){

 

    $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CFB);

    $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);

    $key = "Secret";

    return base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $text, MCRYPT_MODE_CFB, $iv));

 

}

 

 

But an error occurred saying that the function mcrypt_get_iv_size is undefined.Please help me.

Do you have the mcrypt extension installed?
