Subject: mcrypt

Trying to encrypt then decrypt text with php using mcrypt. The encrypt seems to 
work but when I decrypt it with a different script I get most of it but some 
garbage. Using blowfish. So to test.
Encrypt.php
   $iv_size = mcrypt_get_iv_size(MCRYPT_BLOWFISH, MCRYPT_MODE_ECB);
   $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
   $key = "This is a very secret key";
   $text = "Meet me at 11 o'clock behind the monument.";
   //echo strlen($text) . "\n";

  $crypttext = mcrypt_encrypt(MCRYPT_BLOWFISH, $key, $text, MCRYPT_MODE_ECB, 
$iv);
   echo $crypttext. "\n";

decrypt.php

        $server = $_SERVER['SERVER_NAME'];
        $url = 'http://'.$server.'/encrypt.php';
        $fh = fopen($url,'r') or die ("cant open: $php_errormsg");
        $new_string=""; 
while (! feof($fh))
{
$new_string = $new_string.rtrim(fgets($fh,4096));
}

$enc=$newstring;
   $iv_size = mcrypt_get_iv_size(MCRYPT_BLOWFISH, MCRYPT_MODE_ECB);
$enc=$_POST['text'];
$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
$key = "This is a very secret key";
$text = "Meet me at 11 o'clock behind the monument.";
//echo strlen($text) . "<br>";

$crypttext = mcrypt_decrypt(MCRYPT_BLOWFISH, $key, $enc, MCRYPT_MODE_ECB, $iv);
echo "$crypttext<br>";


I get from decrypt
Meet me at 11 o'clock behind the monumen3ýÚ·n_Ãt<br>
Is it doing some padding or something? When I encrypt/decrypt same script it 
works fine.
Maybe something to do with these?
   $iv_size = mcrypt_get_iv_size(MCRYPT_BLOWFISH, MCRYPT_MODE_ECB);
   $iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);



Thanks,
