Security and Technology Ramblings…

This is another one of those cases where I am adding something to my blog so that I wont forget it. If it ends up being of use to you also, then cool.

If you have a protected PDF file that you want to remove the password from and decrypyt, here is how to do it.

For debian / Ubuntu installs, add a program called “qpdf”.

sudo apt-get install qpdf

If your pdf is called “file.pdf”, with a password of “blah”, it would go something like this…

qpdf --password=blah --decrypt file.pdf file2.pdf

So, file2 would have the password removed and be decrypted.

Note, also check out pdftops. You can use it to covert a PDF to a Post Script file. Handy to import a pdf into a word or open office doc.
