> Key: PDFBOX-4413
> URL: https://issues.apache.org/jira/browse/PDFBOX-4413
> Project: PDFBox
> Issue Type: Improvement
> Components: Crypto
> Affects Versions: 2.0.13
> Reporter: Tilman Hausherr
> Assignee: Tilman Hausherr
> Priority: Major
> Labels: AES256
> Fix For: 2.0.14, 3.0.0 PDFBox

>
> 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.
