Some encrypted files don't open

[janxious]

I am generating this PDF via PrinceXML(http://princexml.com): http://dl.dropbox.com/u/599002/DocRaptor/test.pdf

It has no user or owner password set. It is encrypted, however. Based on a brief readthrough of the PDF spec, the trailer seemed correct. It opens without password prompting in Preview and Skim.

The exception trace is:

PDF::Reader::EncryptedPDFError: Invalid password ()

Thoughts?

@3jb can you shed any light on this issue?

I fixed this in the latest commit to my tree 0d1b03cb8. I'm not sure how to create a pull request as it seems to want you to pull an entire set of spurious commits ( 7 - including the original decrypt commits and a set of upstream pulls). How do you deal with that?

Thanks!

To create a clean pull request with just that commit you would have to create a new branch from my master and cherry-pick the single commit, then create the pull request from that branch.

In this case I'll just cherry-pick the commit directly.

Awesome!
