I am encrypting some data on one server and now I am attempting to decrypt on another
server using mcrypt_encrypt and mycrypt_decrypt (using same key and initialzation
vector). It is almost working but I seem to still have a little problem, that data is
missing the last character which still seems to be encrypted. I am putting the data in
the database with addslashes, and retrieving with stripslashes, but I get things like
this;
45221141¤Þ,]¹9Ñ
77777775ÿåZ|z
while($arrEncInfo = mysql_fetch_array($dbGetSub)){
$stripDataA = stripslashes($arrEncInfo['dataA']);
$stripIV = stripslashes($arrEncInfo['iv']);
$dataA = mcrypt_decrypt($encAlg, $encKey, $stripDataA, $encMode, $stripIV);
echo $dataA . "\n";
}
Has anyone seen this? Could there be a difference between the PHP installs? Both are
version 4.3.7.

I found the problem on the field in question. I had left the column in the database
the same length as it was prior to encrypting the data. This, as it turns out, is a
BAD THING [tm]. Make sure that database columns are large enough to hold the whole of
the encrypted data.
