Elly, try using ineptpdf 2. Is this 1.6pdf?

How well does this clean the file. I have successfully decrypted a few pdf's, but question how clean they are. Is it possible for a decrypted file to lets say tracked back to me.

Strange PDF decrypt issue. Go two books from same source and used python to decrypt the first with no problem. Tried the second with the same v3 script and it appeared to work but would not open. So I tried the v5 script next and it gave me an error that says:
"Dict Required 1804"

What does that mean and how do I fix it.

Probably the well known pdf stream dictionary problem.

Thanks joblack. Would you be kind enough to summerize what the well known pdf stream dictionary problem is -- as it is not well known to me. Thanks.

If you have a pdf with a xref stream directory (means the trailer is in a stream and there is no additional trailer) the script doesn't work as it should.

It's a problem of the python script dump method but without some support from a pdf expert it isn't easy to always create a pdf which is standard conform.

So far no pdf format expert gave some help or suggestions for finding the bug (*wink wink*).

I have a problem with PDF 1.6, and I don't know if you can help me. I think I've used all the ineptpdf I found (2, 3, 5, 6) but they don't work. The program always say OK but the result file is encrypted and corrupt. It looks like the programs don't recognize the encryption (Flat Decode). I don't know if the difference is the structure. In a file ineptpdf treats well:

Code:

<</Length    10 /Filter /FlateDecode>>stream

In the wrong file :

Code:

<</Filter /FlateDecode /Length    3890>>stream

Thanks in advance

Flatdecode just means it's decoded in ASCII Code - there is only a difference in the Length value - the rest is not relevant.

I suggest you read earlier posts about the pdf dump method problem ... which most probably is the root of all evil

I don't get it to work. I was able to generate 300 white pages with this tool

Anyone know what went wrong?

Perhaps if you would be more specific (version, what has been done, ...).

Script is giving me this error message "error decrypting book session key" using ineptkey.pyw version 3 and ineptpdf.pyw version 5. At first the script wouldn't run due to an indentation problem, but I commented out the lines that were giving trouble and finally got to run it (it was some text message). Now I'm getting this and I don't have a clue as to what I should do. If you need anymore information just ask me. I read that you were talking about PDF version, however I don't know how to get that piece of information. If it helps, I got the book from netlibrary.com.

The 'format' of the key in the registry has changed with ADE 1.7.2 - either deregister/deinstall 1.7.2 (check in the epub section for a link and more information) and install 1.7.1 or you have to wait for a solution.

I tried with ADE 1.7.1 but the same happened.
