I wonder if there are any plans to enhance the encryption to support 256-bit AES as supported by PDF 1.7 / Acrobat X and above?

Hello Team,
is it possible to implement the 256 bit Encryption in the Output PDF.

Thanks

Is that a question?
It should be possible.

A partial implementation for input PDFs can be found here:

Not on the roadmap for the near future, but I think it would make sense to have it.

We think it would be good to have that new encryption, but we cannot estimate how complicated the implementation will be.
