function GenerateRandomString($Length) {
 $Length /= 2;
 $cstrong = false;
 while ($cstrong != TRUE){
    $bytes = openssl_random_pseudo_bytes($Length, $cstrong);
 }
 $hex = bin2hex($bytes);
 return $hex;
}

Is this a good function for generating a cryptographically secure random string? Is there a chance, that it'll get into an infinite loop, because $cstrong$cstrong stays 'False'?
