Encrypt PDF

At first, select PDF file to encrypt. Then input user password and/or owner password ( N.B. Password should not contain quotes. If your version is less than 0.1.9, it also should not contain spaces ). Then select encryption method and features that will be allowed/forbidden. Features to be allowed should be checked, features to be forbidden should be unchecked.

From version 0.1.6-1 you can overwrite input file with encrypted one.
To do so, select 'No' when asked whether you want to create new file.
