Can't decrypt file because of wrong padding

What steps will reproduce the problem?
1. pdf = Origami::PDF.read('144swan.pdf')
2. pdf.decrypt

I get: Origami::EncryptionError: Data must be 16-bytes padded (data size = 5 
bytes)

What is the expected output? What do you see instead?

I expect the file to be decrypted, as it works fine with qpdf.

What version of the product are you using? On what operating system?

1.2.5, OS X 10.8

Any hints?

Linearized document causes error: Cannot remove last revision

1. Read in a linearized document
2. Write out the linearized document to a new file
3. Error

I'm using the latest gem version 1.2.4.

I've tried adding delinearize => false but the resulting PDF is invalid.

I can't attach the file here as it's a commercial document but I'd be happy to 
send it via email.

Setting EDITOR environment variable?

What steps will reproduce the problem?
1. Load .pdf file: pdf = PDF.read 'sample.pdf'
2. Try to edit: pdf.pages[2].edit

What version of the product are you using? On what operating system?
Ruby 1.9.2-p290, Origami 1.2.3, Windows 7 Enterprise x64

Please provide any additional information below.
In GettingStarted guide said that "the EDITOR environment variable may need to 
be set up", but I don't know how to do that. I'm new to Ruby...
I tried to read all ReadMe-like files in ORIGAMI folder, but there is no 
information about setting EDITOR environment variable. Internet searh also 
doesn't help, Origami's PDF "origami-cheatsheet-1.0.0-beta2.pdf" too... I 
assuming that this feature is un-documented. :(
Can I ask for help here, please?

Thanks in advance.

Kind regards,
Stole

Not able to parse XRef streams

What steps will reproduce the problem?
1. open a pdf that contains an xref stream (see attached script and pdf)

What is the expected output? What do you see instead?
It should just parse the xref table, even if it is in an xref stream, when it 
is in an xref stream you see: 
[info ] Warning: Unable to parse xref table! Xrefs might be stored into an XRef 
stream.

What version of the product are you using? On what operating system?
origami 1.2.3, ruby 1.9.2-p0

Please provide any additional information below.

I believe that the cairo library (http://cairographics.org), which is 
responsible for doing the heavy lifting of pdf generation for a lot of 
different applications does this.

Do not change the operands when to_s is called as it causes debug messages to 
break programs in odd ways.

Walker improvement: show reference number of objects in tree view

This is not an issue but an idea:
Why not improve Walker by adding the reference number of each object in the 
tree view on the left?

For example we could have "5 0 Dictionary" instead of just "Dictionary".

That would be much easier to understand the structure of a PDF when analyzing 
references.

ccittfaxdecode issue when rows > 1

hi,

I was porting your ccitt.rb to python, for using in peepdf, I found when 
decoding stream with multi rows, the current_color should be initialized as 
white in the loop, rather than initialize once.

HTH,

Please include tests in releases uploaded to rubygems

I am packaging origami for Debian, and having the tests included in the 
releases lets us run them both during package build and on the Debian CI 
service.

The current build system has a typo that makes the test files not be included 
in the releases (except tc_pdf.rb which is listed in test_file). The attached 
patch fixes that.

It would be really nice if you could make a new release after applying this 
patch.

Support filter abbreviation

Hi,

PDF filter has abbreviation. For example, FlateDecode can be written as Fl, and 
ASCII85Decode can be written as A85. I wrote a patch to support all 
abbreviations, please help to see if this patch is suitable to merge into 
mainline.

For detail of abbreviation, please see the following link.

Cannot compute correct okey in AESv3 R5

Hi,

In step 3 of algorithm 3.2a of [1], the algorithm to computer the intermediate 
owner is described as following:

file_encryption_key = AES256 {
    data: OE
    key: SHA256(owner_password + O[40:48] + U) 
    mode: CBC, no-padding
    IV: 0
}

However, the implementation seems to forget the U key part when calculating 
AES256 key. This patch adds self.U to conform [1].

Issues with using Origami in REMnux

What steps will reproduce the problem?
1. installed the JS dependency therubyracer
2. attempted to create a PDF which went to a URL
3. attempt to create a PDF with Javascript

What is the expected output? What do you see instead?

I followed the instructions on the webpages on the 'Getting Started' under the 
wiki as well as the example on http://esec-lab.sogeti.com/pages/Origami.

For the URL example, it looked like the action (adding the URL) did not take 
place. I save the 'new' PDF and opened with Wireshark running, no request was 
made out. 

For the Javascript, I here is my input and subsequent output:

>>> pdf.onDocumentOpen Action::Javascript.new('app.alert("Hello!")')
NameError: uninitialized constant Origami::Action::Javascript

    from :0

*OS: Remnux v3.0


Please provide any additional information below.
I was having issues with a date format specification in the file 
'therubyracer-0.9.9.gemspec' however found a workaround. Not sure if that is 
the issue, but wanted to address it as it could be part of the problem! I also 
ran 'gem update' and 'update_rubygems'
