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.
Am sorry if my question is too confusing, what I mean is, when a password filled encrypted file using the trial version of encryptpdf via the command line, it can be opened using the pdf vista viewer without asking for the password of the file. Do you have a newer version of the encryptpdf in command line which supports the password filed option? Or do we really have to buy the version that would support the said problem?
You can run following command line to encrypt your PDF file without "open" password, you can view output PDF file without password,
EncryptPDF -i c:\sample.pdf -o C:\out.pdf -w owner -e 40 -p
You can also encrypt your PDF file with "open" password, you will be prompted by a password when you open this PDF file,
EncryptPDF -i c:\sample.pdf -o C:\out.pdf -w owner -u user -e 40 -p
