Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Halo APV PDF Teams,

   I want to ask about encryption or other pdf secure method.  Are there any protection method to secure pdf file except the pdf file with password.

What steps will reproduce the problem?
1. user view in APV viewer, and then
2. user copy the pdf from the storage and crack (bruteforce) the password and 
share with others.

What is the expected output? What do you see instead?
1. user can read using APV viewer
2. even the user can copy the pdf file, but they need more than just crack the 
password.  is there any solution for securing pdf file or is there any way to 
custom how the pdf engine load the pdf file so we can add out custom encryption?

What version of the product are you using? On what operating system?
We using APV 0.3.1dev9 and Android 2.2.

BR,
Limhongwen
