Bug description: Mcrypt decrypt output bug in Firefox
Description:
------------
Following an MCRYPT example on php.net, when decrypting a string that is
less than 8 characters, will output in firefox and appended with ? marks to
fill the other characters.
Example: ecrypted string is 4 characters long (abcd), when decrypting the
string and outputting to firefox displays: abcd????
This was tested with Firefox 2.0.13. This does not appear to affect
Internet Explorer 7.
Reproduce code:
---------------
$key = "d9Qg%R*";
$text = "abcd";
$iv_size = mcrypt_get_iv_size(MCRYPT_XTEA, MCRYPT_MODE_ECB);
$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
$enc = mcrypt_encrypt(MCRYPT_XTEA, $key, $text, MCRYPT_MODE_ECB, $iv);
$crypttext = mcrypt_decrypt(MCRYPT_XTEA, $key, $enc, MCRYPT_MODE_ECB,
$iv);
echo $crypttext;
Expected result:
----------------
echo output should be: abcd
Actual result:
--------------
echo output is actually: abcd????
