I think i've asked this before, but here goes.

I'm trying to remove Adobe Acrobat PDF security.  It's 64 bit encryption.   Passware and pdftools 1.3 can't do it.   Does anyone have any suggestions or methods? or is this a lost cause?

also, would anyone care to take a stab at removing the protections?

Hi,

i have tested the AEBPR tool by Elcomsoft (posted above).
i have the same error as dfc.
in the help of the progg it is explained vaguely *why* this error happens.

i never understood.

A tougher question is how do you remove Zinio security so it doesn't "phone-home" all the time!

(You can't open the file if you block the reader thru a firewall)

Reason i'm asking is cuz it's a drag when you're trying to read a zinio mag for the first time and you don't have Internet access...

a zinio magazine has to be activated the first time, any time after that just disconnect before u open the magazine, an error message will come up > press ok and ther you go

but
the magazine has to be activated (this happens first time you open it)

the activattion info is stored in xml files

It's pointless to share a zinio mag unless you have the XML license file to share as well.  So don't waste your time downloading zinio format mags unless you can see an XML license file accompanying the download.

Back to topic, I've used Elcomsoft's Advanced PDF Password Recovery Professional for some time now, and it's worked every time for copy and print protected files.  I haven't tried it on a PDF file which requires you to enter a password even before you open the file though, so if someone has a test PDF to share, I can test this.

I tried this kind of PDF before, and it doesn't work. It said we need to have user password to remove system password. I am not sure if there is "more advance" option from this software that we can remove user password or other software with similar functionality.

If you know, please let us know :)

The problem with the new 128bit encryption, there is no tool (yet) to decrypt pdf's with those files. Also I am having problems with pdf  1.6 (or Acrobat 7.x) documents.

Any suggestion on how to crack their secutiry

Cheers,

Icosium
