Yes, I used the same permissions throughout - the only permission allowed was ALLOW_PRINTING (which is our standard setting for this kind of generated PDF). In case it's important, the encryption strength is ENCRYPTION_AES_128 > In that case, I'm going to guess you need to add the > PdfWriter.ALLOW_FILL_IN flag to your setEncryption call.

Ahh, thanks for that, I hadn't realised the permissions would be applied to the itext manipulations done on the PDF, I thought they came into force when the stamper was closed. I also hadn't realised what the ALLOW_FILL_IN permission was for. I've added the new permission to the list and it looks like we're a step closer. ALLOW_FILL_IN does allow our code to fill in the XFA form. However, once secured, the final PDF also allows users to edit the form fields. What I'm hoping to do is open the unsecured PDF, fill in the XFA fields, and produce a filled in, secured PDF, which subsequent viewers cannot edit (or at least cannot save/print those edits). Is there anyway to do that? Or are the options only secure but unfilled XFA fields, or filled but unsecured XFA fields?
