I can see that we can open password protected pdf with pdf.js express viewer.
but when I compare PDF.JS EXPRESS VIEWER vs PLUS
I can see that
Support for 128 bit AES (Advanced Encryption Standard) encryption include only pdftron.
Then what are the differences with open enrypted pdf?
Can I do that on viewer and plus version?
and the second one related to licenses: can we select and export annotations area in both versions (viewer and plus)?
