If it's anything less, you're going to get some garbage at the end of the decrypted ciphertext.

[PHP] occasional mcrypt problems
Hello,
I recently implemented a database using MySQL that is storing selected
fields encrypted. However on a very small number of records the decrypted
result is not correct for some fields, for example for this credit card
number:
-99-ÏF¡hßxø
It appears in fact the same way as the problem I first experienced, when the
database field was not big enough to store the encrypted text (which I
discovered takes a multiple of the blocksize, so it is usually bigger than
the original string). However the blocksize is 8 and to provide a safety
margin all the fields to be encrypted have 10 extra characters in them
(varchar fields).
So far this happens on at most one field in a record, perhaps on less than
5% of the records. At first I was thinking maybe the addslashes() was
adding text but MySQL should be stripping that out before entering it into
the database, right? Also I can't seem to duplicate this by entering the
same values in the form again.
Any suggestions? Here is my encryption code:
$hrkey = '$R^a$nd()M%'; // changed text
$td = mcrypt_module_open(MCRYPT_TRIPLEDES,'', MCRYPT_MODE_ECB, '');
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), 99);
//changed the number
$ks = mcrypt_enc_get_key_size ($td);
$key = substr(md5($hrkey), 0, $ks);
mcrypt_generic_init($td, $key, $iv);
$CreditCardNumber = addslashes(mcrypt_generic($td,
$_POST['Credit_Card_Number']));
(...post to database here...)
mcrypt_module_close($td);
Decryption code:
function mydecrypt($enc) {
global $td;
return rtrim(mdecrypt_generic($td, $enc), \0);
}
Thanks for any insight!

[PHP] Re: mcrypt 2.4.x - trouble with small data fields?
Is there a minimum field size for using mcrypt? Boy I feel dumb now. :) My answer was in my post. Mcrypt returns a string that is usually longer than the original string, since the return has to be a multiple of the block size used. So a 2-character string takes blocksize characters when encrypted. Mcrypt also apparently needs the extra characters when decrypting. - Steve Yates - If at first you don't succeed, lower your standards. ~ Taglines by Taglinator - www.srtware.com ~ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] mcrypt 2.4.x - trouble with small data fields?
On my current project I am saving personal info into a MySQL database
for later retrieval. I have discovered that I have trouble with a few
specific data entries, though the other ~20 work fine. The two I have
trouble with are a char(2) and a varchar(4) field, the smallest ones in the
table, and they return garbage when decrypted. Is there a minimum field
size for using mcrypt? Sample code:
// to encrypt, init once
$mykey = 'keytext';
$td = mcrypt_module_open(MCRYPT_TRIPLEDES,'', MCRYPT_MODE_ECB, '');
$iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), 1234567890);
$ks = mcrypt_enc_get_key_size ($td);
$key = substr(md5($mykey), 0, $ks);
mcrypt_generic_init($td, $key, $iv);
(...)
$CreditCardExpMonth = mcrypt_generic($td, $_POST['Credit_Card_Exp_Month']);
(...)
// then save to database as part of insert query
If I save/retrieve the fields to/from the database w/o encryption they
save retrieve fine. This field is two digits ('02', '11', etc.). The
other is the year (4 digits).
// to decrypt
// I wrote a function to truncate the returned string at the
// first \0 since mcrypt's decrypt pads the result
echo mydecrypt($data['CCExpMonth']);
function mydecrypt($enc) {
global $td;
$str = mdecrypt_generic($td, $enc);
$pos = strpos($str, \0);
if ($pos !== false) {
$str = substr($str, 0, $pos);
}
return $str;
}
Also as long as I'm posting, mcrypt_generic_deinit() seems to be
undefined on my system? Is that an mcrypt issue or an interaction between
PHP 4.1.2 and mcrypt 2.4.x?
