what platform or version of PDF viewer does the trial version of your encryptpdf in command line supports

Good day!

I just would like to inquire up to what platform or version of PDF viewer does the trial version of your encryptpdf in command line supports? If we would avail or buy the encryptpdf in command line would it be able to support the password filled option if the user opens the pdf file in pdf vista viewer?

==========================

The PDF file which encrypted by EncryptPDF Command Line product can be viewed by all version of Adobe Reader, from Adobe Reader 1.0 to 9.0, so please don't worry about this matter.
