I've just received a PDF that I wanted to convert for my ebook-reader,
but it was protected with a password + was restricted for printing. So I
didn't have a chance to convert it into a suitable format for it. ahm...
aren't there some tools around to decrypt stuff like that...? ;-)
Yes, qpdf seems to be the tool! It can
encrypt/decrypt among other things and runs windows (cygwin) and *nix.
So in my case, it's as simple as that:
{.lang:sh .decode:true}
qpdf --password=password --decrypt encrypted_input.pdf decrypted_output.pdf
Hope somebody finds it as useful as I did :-D
Thanks for reading!
