> When writing a PDF using AES 256 bit encryption, the field names / values from the Acroform are not being persisted correctly. If I encrypt using RC4 128 bit, they are persisted correctly. I am using snapshot pdfbox:2.0.0-20141023.180319-636.
> I dug into this, and it looks to me the problem is with COSWriter.visitFromString, which invokes  SecurityHandler.decryptString (there is no SecurityHandler.encryptString).
