I'm interested in adding strong encryption to PDF files on iOS (128-bit AES or higher). Is this supported? If not, when will it be supported?
Apologies for the previous response.
The Acrobat mobile application do not support adding the strong encryption you are referring to.
Let me know if you need any more help.
Thanks for replying. That is literally the only feature that I need Please consider adding the functionality in the future. I'd be happy to pay $10 for it.
