encrypt->decode producing blank output - El Forum - 01-22-2010

Hi,
I've used the encryption library with CI before and have not had a problem, however at the moment, something is driving me nuts and I can't figure out why it won't work.
My database has a field which gets encrypted when I post a form. I can view the resulting encryption and it looks fine.
I then do a query, pull out the data and when I try to display the decoded encryption I get a blank. If I don't decode it, I can see the encrypted version of the field. Here is a cut-down version of the code. Can't see what's wrong here and as I say it's working perfectly on another app!
Code:
<?php foreach($query->result() as $item): ?>
...
<input type="text" name="customerName" value="<?=$this->encrypt->decode($item->customerName);?>" />
...
<?php endforeach; ?>The outputted field value is blank!
Can anyone shed any light on this?

Incorrect encryption key in the config?

Thanks noctrum. I just figured it out. I had my fields set as varchar with a length of 35. I had forgotten that the encryption function can make the encrypted fields up to 3 or more times the length after encryption. I changed my fields to TEXT format and now it's working fine,
Just out of interest. Would it be a good idea to MD5 the result to end up with consistent sized results?
cheers,
Wittner

Thanks for pointing that out Demedes. I feel suitably chagrined and I shall change my php tags forthwith!
