How to apply an open password to a PDF file using advanced pdf tools command line software?

I just downloaded advanced pdf tools command line 3.0.

I ran the test-encryption.bat.

As expected, it created a pdf test-encryption.pdf

But the PDF did not require an open password.

Does the trial version correctly work to apply an open password?


Thanks for your message, yes, the trial version does able to apply an open password to a PDF file.

You may run following command lines to apply an open password or only owner password to a PDF file,

pdftools.exe -S openpwd=123 -S ownerpwd=456 -S keylen=2 -S permission=129 -i test.pdf -o _test-encryption-with-open-password.pdf

pdftools.exe -S ownerpwd=456 -S keylen=2 -S permission=129 -i test.pdf -o _test-encryption-without-open-password.pdf
