      Description

      Adobe 9 added support for AES 256 encryption. This should also be implemented for public key encryption, currently it is only implemented for symmetric key encryption.

      Further information is available at http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/adobe_supplement_iso32000.pdf.

      I suspect that much of it is already available in the base class, but PublicKeySecurityHandler.prepareDocumentForEncryption() is definitively old stuff.
