Tilman Hausherr commented on PDFBOX-5092:
-----------------------------------------
I don't see how this is a "task". It sounds like a how-to question, which
should be asked in the users mailing list. Please do so and include the code
you used.
AES encryption is used if you set the key length to 256.
> Used PDFbox for document download but for encryption it is currently pointing
> to MD5. I want to avoid using of MD5 and use only AES. Can you suggest what
> changes I need to follow to achieve the AES encryption
