Please can you give us an example of how to use the PDFAESStream code? We are download streaming large unencrypted files, and wanting to encrypt them before saving to the windows phone storage. We will then decrypt them once reading them from the disk before opening.
We haven't yet purchased the product, so want to see how well the encryption can be integrated before purchasing.
The better way to encrypt PDF and protect contents should be to store pdf file with native as encryption.
if you are receiving unencrypted files from your server you might encryptAs() using Premium license.
