Hello!
I've problems to decrypt pdf-docs encrypted with Acrobat 7/8. QuickPDF shows me with older pdf-docs 40- or 128-bit-encryption ... working with the new (7/8) pdf-docs the library shows nothing readable. Is here someone with a hint or idea for me? Thanks in advance and ... Best regards and a Happy 2007, Ingo |

Ingo, some months ago I have tested some PDF documents encrypted with Acrobat 7. The problem was that QuickPDF library does not properly read the Acrobat 7 (PDF spec 1.6) metadata fields used for encryption. If this is your case someone must invest some time studying the documentation :-(

Hi!
I think the problem is the new (1.6) encryption standard AES. Before 1.6-specs the encryption standard RC4 was used. Actually QuickPDF can't work properly with AES-files. Are there some hints... some ideas? I don't want to read the whole 1200 pages ;-) Best regards, Ingo Edited by Ingo - 10 Jan 07 at 1:53AM |
