Novice users will appreciate the easy-to-use approach offered by this encryption program for PDFs, while more advanced users will like its flexibility.
The program's wizard-like interface walks you through the encryption process step by step. Add the files, choose the encryption level (128 bits or 40 bits), and then apply any permissions for the recipient. For example, you can choose to allow printing, copying, or changing the PDF, or all of the above. You can also select the output folder, so you'll know exactly where to find encrypted files. A status bar displays the encryption progress. Files can be password protected, but the password cannot be changed during the trial. The encryption process was quick and permissions were accurately applied to the file.
