Hi joblack,
I was debugging the script, and found that the error was because of the lenght of the book session key in line 1196 (v3 of the script). Maybe there's something wrong in RSA decrypting so that the decryption of the streams does not work.
The RSA decryption is based in the AES key generated by ineptkey script. Maybe is not an AES CBC_MODE key for PDF older versions. i♥cabbages said that uses AES in CBC mode with a random IV... or maybe is not RSA with PKCS#1 v1.5 padding, who knows?
All of these questions influence the dump method, because my "decrypted" PDF has the correct structure.
