Watermarking and encrypting a PDF

PDF files have some interesting security measures to limit the distribution of a document. We can encrypt the content, making it necessary to know a password in order to be able to read it. We'll see as well how to add a watermark to label the document clearly as not for public distribution and, if leaked, to know its origin.

Getting ready

We'll use the pdf2image module to transform PDF documents to PIL images. Pillow is a prerequisite. We'll also use PyPDF2:

$ echo "pdf2image==0.1.14" >> requirements.txt
$ echo "Pillow==5.1.0" >> requirements.txt
$ echo "PyPDF2==1.26.0" >> requirements.txt
$ pip install -r requirements.txt

For pdf2image...
