Adobe ADEPT DRM for EPUB circumvented

OK. I uninstalled Python 26. I then installed Python 2.61, and pyrocrypt. I then copied both scripts to my desktop, saved them to a file I created C:\EPub and renamed them to .pwy. When I doubleclicked on the icon, nothing happened. So I ran the script from the command prompt C:/. Here is my screen shot:

Traceback (most recent call last):
File "C:\Python26\adeptkey.pyw", line 197, in main
retrieve_key(keypath)
File "C:\Python26\adeptkey.pyw", line 139, in retrieve_key
vendor = cpuid0()
File "C:\Python26\adeptkey.pyw", line 102, in cpuid0
cpuid0__(buffer)
WindowsError: exception: access violation writing 0x019F79D0

Any help would be greatly appreciated.

1. Create a copy of the adeptkey script right in the root of your C: drive. So you should navigate to your C: drive and see "adeptkey.pyw" right there.
2. Use the Windows "Start" menu (or whatever they call it on Vista) and select the "Run" option.
3. Type "cmd.exe" (without the quotes) and press "enter" or click "ok"
4. In that window, type "cd c:\" (no quotes) and press "enter"
5. Then type "Python26\python.exe adeptkey.pyw" (still no quotes) and press enter.

If it doesn't generate the key, please attach a screenshot of what happens.

I don't know how to do a screen shot of the cmd.exe, but when I did exactly the above, this is what I got

C:\>Python26\python.exe.adeptkey.pyw
File "adeptkey.pyw", line1
SyntaxError: Non-ASCII character '\xff' in file adeptkey.pyw on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

Thanks. I am going to try and check out the python html. Debra

I think I am getting somewhere. If I simply rename the file, and run it from my desktop, it opens a command prompt window, and on top of that I get the following:

Traceback (most recent call last):
File "C:\Users\Debra\Desktop\adeptkey.pyw.txt", line 197, in main
retrieve_key(keypath)
File "C:\Users\Debra\Desktop\adeptkey.pyw.txt", line 139, in retrieve_key
vendor = cpuid0()
File "C:\Users\Debra\Desktop\adeptkey.pyw.txt", line 102, in cpuid0
cpuid0__(buffer)
WindowsError: exception: access violation writing 0x019F1570

PS: Adeptdecrypt.pyw runs fine.

Just click your command prompt window to activate it, then press the keys 'Alt' 'Print Screen'
(like you would press 'shift' 'A').

Now find and launch the MS Paint program or your favourite graphics editor and Paste...

Presto, window screen shot. For the entire screen, press 'Ctrl' 'Print Screen".

If adeptdecrypt.pyw strips the DRM, then you already have a good key, in adeptkey.der, and you don't need to run adeptkey.pyw again. If not, I assume you have adeptkey.pyw version 2?

This looks like it is trying to write the file and can't. I could be wrong but.. what OS are you running? Is it Vista?

Yes, dreaded vista. Adeptdecrypt runs, but I don't have the key, yet. Just need that.

These are two entirely different errors, which is making this harder to diagnose. The first one means that you saved the Python script as something other than ASCII, in this case seemingly UTF-16. Open a new instance of notepad, showing a completely empty file. Copy-paste from the web page again, making certain to copy from the text-box and not from the syntax-colored page content.

The second error means that one of the embedded machine code functions in the Python script attempted to access invalid memory. But (a) I have absolutely no idea in hell what could be causing that and (b) when I simulate generating an access violation I get the exception-trace window I added for adeptkey v2. I'd say that you're still running v1, except the line numbers from the exception traces match v2.

I'm hoping the second error is somehow an artifact of the encoding problem causing the first error. If not, I'm out of ideas.

Turn off UAC. What I am thinking is that adeptkey isn't allowed access to where Adobe Digital Edition stores the key. UAC is nothing more then Microsoft telling you you cannot have access to your system to do what you want. So turn UAC off and never look back. If you don't know how to turn UAC off, look in Help and Support and type in UAC. That will help you turn it off.

Bad advice IMHO. If you're not very computer savvy, you'd better leave UAC on. And it doesn't interfere with the script, I used Vista when uncloaking my key.

BTW, both scripts work in wine as well as I found out later.

But it also depends if the account that is being used on Vista has administrator privileges or not. UAC is best left turned off. It was a bad idea by Microsoft. Besides, I do not enjoy having to authorize everything I want to do on MY system. This is why I turned off UAC on our laptop.

Presumably if you are able to use ADE and it needs to read the Key from somewhere... then your user has rights to read it. So, your user account has rights to read it, so it will when you run this script.

Also, if you were running UAC and the program requested access to something your non-elevated token it should request elevation via the UAC prompt.

Even with running UAC you can start the command window "as administrator" and then any process it spawns will also have full admin rights.

Many people blame UAC for things it isn't responsible for. Although UAC is mostly annoying because many apps still are written properly for Vista and/or to run as "standard user" account.
