It seems that the
code that encrypted it reads the PDF file right-side up, but retains the
rotation value of the old PDF file. Here’s the code if you would like to
look. It just seems so odd to me too:

Upside-down? This is
a novelty! I would like to see the pdf and the program used to encrypt
it.

Subject: [iText-questions] Encrypting
PDFs makes the encrypted version upside down.
I have a problem encrypting
PDFs. It creates the encrypted PDF upside down. Is this a bug
with iText? The PDF was created with the version 1.2
specification.
