Hi there,
I can confirm that in the 5.22 version there was a bug affecting document with normal PDF encryption :-(

Hi Marian,

I don't know what a dictionary is, as it relates to a PDF file. From what I posted, do you think this may be the cause of what I'm seeing?

If you can send me a DLL binary, I will test what you have. The binary I currently have is 5.22. (I'm not sure from your post if you mean you have something more recent than what is in the public download page.)

Guys, in 5.22 I have solved a huge bug with the decryption of PageTree dictionary. Because of a strange caching of Page references overwritten with some access optimization it was impossible to decrypt dictionaries although the document had all the information needed.

Can you please test the last version in an attemt to confirm my sollution.
 
Thank you, Marian

I am having a problem with decryption as well, though I don't know if it's the same problem or different.

My encryption is performed by QuickPDF, at 128bits, with both an owner and user password. When the saved file is opened in Acrobat Reader (6.0), it accepts both passwords and properly handles the document, along with the permissions I set from within QuickPDF.... so it appears there is no problem with encryption.

When I decrypt from within QuickPDF I don't get an error back -- the return value is proper according to owner or user password as provided. There are two glaring problems that I can see though. My document consists of a background image, and 68 form fields.

When decrypted by QuickPDF, it still agrees that there are 68 form fields. For each of them, it seems to also know the proper bounds. (I haven't checked to see if these things would be seen if I did not decrypt the document.)

Problem 1: the background graphic will not display from QuickPDF's rendering anymore.

Problem 2: the field titles are all scrambled. I haven't checked Acrobat Pro to make sure it can interpret them correctly still, but since Reader displays the background graphic properly still, I suspect it may.

I actually tested this function with a PDF that is at 1.6, is encrypted with 40bit RC and the Unencrypt did not seem to work.]]> Fri, 09 Mar 2007 14:30:46 +0000 http://www.quickpdf.org/forum/problems-with-encrypted-pdfs_topic558_post3162.html#3162 <![CDATA[problems with encrypted PDFs : I fear it&#039;s not included:...]]> http://www.quickpdf.org/forum/problems-with-encrypted-pdfs_topic558_post3161.html#3161 Author: ukobsa

I fear it's not included: I just have looked on the source (5.21) and only the second change is included as a comment. Maybe Marian has found another solution so that my original code is obsolete.
